20150227408
The present invention relates to an information processing unit and program and is suited for use in an information processing unit and program for monitoring various devices and various jobs operated on the devices.
Recently, with respect to operation and management of a computer system, there is a demand for not only management and monitoring on the basis of units of devices (computer equipment such as servers, storage equipment, network equipment, and databases), but also for management and monitoring on the basis of units of jobs operating on the devices.
So, upon the occurrence of a failure in a computer system for executing a plurality of jobs, Patent Literature 1 discloses a technique that not only specifies the location of the failure on a device basis, but also efficiently recognize the details of the failure and the range of influence caused by the failure. In the case of the occurrence of a failure, Patent Literature 1 can specify the failure and easily recognize the range of influence caused by the failure by displaying job configuration information, logical configuration information, and physical configuration information related to jobs to a job administrator who manages each job.
[Patent Literature 1] U.S. Pat. No. 4,804,139
However, Patent Literature 1 displays only the configuration information about a target to which the job administrator can refer. Therefore, if a failure occurs at a device which the job administrator cannot refer, the problem is that the job administrator cannot recognize the failure of the device even if the failure has an influence on a job of the management target.
The present invention was devised in consideration of the above-described circumstances and aims at suggesting an information processing unit and program capable of specifying a device related to an management target of an administrator and elements constituting the device and providing status information about the management target in consideration of the status of the above-mentioned device and elements.
In order to solve the above-described problem, provided according to the present invention is an information processing unit for monitoring a plurality of monitoring target devices, the information processing unit including: a memory unit for storing configuration information and status information about each of the monitoring target devices; a control unit for monitoring status information about the monitoring target device and a component including a function and part constituting the monitoring target device; and a display unit for displaying status information about the component; wherein the control unit defines one monitoring target group including the monitoring target device or the component of the monitoring target device as input by a monitoring user; and wherein when a first component is included in the monitoring target group and there is a specified relationship between the first component and the second component and if a failure occurs at a second component, and if a status of the first component is to be displayed via the monitoring target group, the control unit displays that the first component is in a critical state; and if the status of the first component is to be displayed without intermediary of the monitoring target group, the control unit displays that the first component is in a normal state and the first monitoring target device or the second component is in a critical state.
When the above-described configuration is employed and if the monitoring target device or the first component is added to the monitoring target group and a failure occurs at the second component, and if the status of the first component is to be displayed via the monitoring target group, the control unit displays that the first component is in a critical state; and if the status of the first component is to be displayed without intermediary of the monitoring target group, the control unit displays that the first component is in a normal state and the monitoring target device or the second component is in the critical state. As a result, it is possible to efficiently recognize influences on the management target at the time of the occurrence of a failure by specifying a device related to the management target of the administrator and elements constituting the device and providing status information about the management target in consideration of the status of the above-mentioned device and elements.
According to the present invention, it is possible to efficiently recognize influences on a management target at the time of the occurrence of a failure by specifying a device related to the management target of the administrator and elements constituting the device and providing status information about the management target in consideration of the status of the above-mentioned device and elements.
An embodiment of the present invention will be explained below in detail with reference to drawings.
Incidentally, information about this invention will be explained in the description below, using expressions such as “aaa tables,” “aaa lists,” “aaa DBs,” and “aaa queues,” but these pieces of information may be expressed by means of other data structures such as tables, lists, DBs, and queues. Accordingly, information such as “aaa tables,” “aaa lists,” “aaa DBs,” and “aaa queues,” may be sometimes called “aaa information” in order to indicate that such information does not depend on the data structures. Moreover, expressions such as “identification information,” “identifier,” “name,” and “ID” are used when explaining the content of each piece of information, but they can be replaced with each other.
The following explanation may be given by using the word “program” as a subject. However, since a program is executed by execution of specified processing by a processor using a memory and a communication port (communication control device), the processor may be used as a subject in the explanation. Also, the processing disclosed by using a program as a subject may be processing executed by a computer such as a management computer or an information processing unit. Moreover, part or all programs may be implemented by dedicated hardware.
Furthermore, various programs may be installed in each computer by means of storage media which can be read by a program distribution server and the computer.
(1) Outlines of this Embodiment
The outlines of this embodiment will be firstly explained. Conventionally, the operation of nodes which constitute a network, such as servers, storage apparatuses, and network equipment, has been monitored on a node basis. Also, the operation of devices such as the servers and the storage apparatuses has been monitored on a device basis and the operation of jobs including the servers and elements constituting the servers such as logical volumes and ports (hereinafter referred to as the components) has been monitored on a job basis.
However, the conventional technology allows a job administrator to monitor only the status of nodes and components to which they can refer, so that the job administrator cannot recognize the status of components which are not related to a job group which is a management target. Therefore, if a failure occurs at a component that does not belong to the job group which is the management target, it is impossible to judge whether or not that failure will have an influence on the job group which is the management target.
For example, according to the conventional technology as illustrated in
Accordingly, in this embodiment, when the job administrator adds a component(s) constituting a job group, a component(s) which serves as the basis for the relevant component(s) (hereinafter sometimes referred to as the base component(s)) is specified. Then, the status of the component constituting the job group is provided in consideration of the status of the base component.
For example, in the case of the above-described example, let us assume that the job administrator adds Server 1 and the logical volume LU1 as components constituting a job group. In this embodiment, base components such as a power source and a controller which will have an influence on the status of Server 1 and the logical volume LU1 are specified. Then, the status of the components is decided in consideration of the status of the specified base components, that is, the status of the power source and the controller.
As a result, devices related to the administrator's management target (components) and elements which will have an influence on the devices (base components) are specified, the status of the components can be decided in consideration of the status of the base components. Moreover, it is possible to efficiently recognize the influence on the management target at the time of the occurrence of a failure by displaying status information about the component(s) depending on the status of the administration such as the device administrator or the job administrator.

Moreover, the display 206 is a display device for displaying the display configuration information 221 and the display status and performance information 222 by means of texts or images.
Next, the configuration of the server 400 and the storage apparatus 500 will be explained with reference to
The server 400A includes a CPU 401, a memory 402, a first disk drive 403A, a second disk drive 403B, a third disk drive 403C, a power supply unit 404, and an agent 401 as illustrated in
The CPU 401 serves as an arithmetic processing unit and control device and controls the entire operation in the first server 400A in accordance with various programs stored in the storage device 402. Moreover, the CPU 401 may be a microprocessor. The memory 402 is composed of, for example, a ROM (Read Only Memory) or a RAM (Random Access Memory).

The power supply unit 404 is a device for supplying power to the first server 400A. Moreover, the agent 401 monitors the status information about the server 400A and provides it to the management computer 100.
Since the second server 400B has the same configuration as that of the first server 400A, any detailed explanation about it has been omitted.
Moreover, the storage apparatus 500 includes, for example, parity groups 501A and 501B, a first controller 503A, a second controller 503B, a first power supply unit 504A, and a second power supply unit 504B.
The parity groups 501A and 501 B are groups of hard disk drives to implement RAID configurations. A RAID group is defined with a plurality of storage devices and one or more volumes are defined in storage areas provided by one or more storage devices constituting one RAID group. Referring to
The first controller 503A and the second controller 503B have a function that manages volumes in hard disks; and the first controller 503A manages the first volume 502A and the second volume 502B and the second controller 503B manages the third volume 502C and the fourth volume 502D.

Furthermore, as illustrated in
In this embodiment, CPU 1 (the CPU 401), Memory 1 (the memory 402), and Disk 1 (the first disk drive 403A) are automatically added as components which constitute Server 1. Moreover, Parity Group 1 (the parity group 501A) and Controller 1 (the first controller 503A), which are upper components of Volume 1, are automatically added as components which constitute Volume 1. Furthermore, Power Unit 1 (the first power supply unit 504A) and Power Unit 2 (the second power supply unit 504B), which are base components of Parity Group 1, are automatically added.
Accordingly, in this embodiment, for example, upper components and base components which will have an influence on a node or component added to a job group by the job administrator are automatically added in accordance with a specified rule. Furthermore, the status information about the added component is acquired and the status of the nodes and components necessary for a job is presented to the job administrator in consideration of the status of the base components which will have an influence on them.
For example, if Volume 1 and Server 1 are added to group Gr by the job administrator as illustrated in
On the other hand, regarding devices registered in the device management group Gr of the device administrator, it is only necessary to know whether or not the status is normal on a device basis. So, if the power of Power Unit 1 goes off, it is determined that the status of Power Unit 1 is not normal and the status of Volume 1 is normal.
Accordingly, in this embodiment, the status of the components can be changed and displayed depending on the status of the administrator, so that it is possible to effectively provide information which is required by the device administrator or the job administrator to manage the devices and the components.

A component table 602 is a table for managing the configuration of the components; and is constituted from a node ID column 6021, a component ID column 6022, a component type column 6023, and a status column 6024 as illustrated in
The node ID column 6021 stores information for identifying the relevant node. The component ID column 6022 stores information for identifying the relevant component. The component means a function or part of the node as described earlier. The component type column 6023 stores information indicating the type of the component. The component type can be, for example, a CPU, a memory, a disk drive, or a logical volume. The status column 6024 stores information indicating the status of the component. When the component is in a normal state, “Normal” indicating the normal state is stored; and when the component is not in a normal state, “Critical” indicating the critical state is stored.
Next, the dependence relationship of components will be explained. A component relation table 603 is a table for managing the dependence relationship of each component; and is constituted from a node ID column 6031, a component ID column 6032, a relationship column 6033, and a related component ID column 6034 as illustrated in
The node ID column 6031 stores information for identifying the relevant node. The component ID column 6032 stores information for identifying the relevant component. The relationship column 6033 stores information indicating the relationship with a related component described later. The related component ID column 6034 stores information for identifying a component on which the component stored in the component ID column 6032 depends, or in which that component is included.

The member component ID column 6043 stores identification information about components constituting each node.
Next, the status management information about components will be explained. A component status management table 605 is a table for managing the status of components; and is constituted from a group ID column 6051, a node ID column 6052, a component ID column 6053, a rule ID column 6054, a parent path name column 6055, a quantification quantifier column 6056, a general column 6057, a base component status 6058, and a status column 6059 as illustrated in

The parent path name column 6055 stores information indicating a path name of an upper component of each component in a tree structure of the relevant management group. When there are a plurality of base components on which the component depends, the quantification quantifier column 6056 stores information indicating a standard for deciding a general status of the base components. For example, if there is at least one component, which is not normal, among the plurality of base components, the quantification quantifier column 6056 stores “Any” indicating that the general status of the base components is not normal (critical). Moreover, if all the plurality of base components are not normal, the quantification quantifier column 6056 stores “All” indicating that the general status of the base components is not normal (critical). Moreover, if n pieces of components are not normal among the plurality of base components, the quantification quantifier column 6056 stores “+n” indicating that the general status of the base components is not general (critical).
Furthermore, the general column 6057 stores information indicating the general status of the base components as decided by the aforementioned quantification quantifier. The status column 6059 stores information indicating the status of each component.

The additional component type column 6063 stores information indicating the type of an additional component as a base component of the relevant component according to the type of the component. The quantification quantifier column 6064 stores information indicating the aforementioned quantification quantifier.
The search method column 6065 stores information indicating a search method, that is, “Order” or “Reverse.” The relationship column 6066 stores information indicating the relationship between the component and the additional component. If the component depends on the additional component, the relationship column 6066 stores “Depend”; and if the component is included in the additional component, the relationship column 6066 stores “On.” The whether-to-add-or-not column 6067 stores information indicating whether or not to add the additional component to the target component. For example, if the additional component is to be added, the whether-to-add-or-not column 6067 stores “Y”; and if the additional component is not to be added, the whether-to-add-or-not column 6067 stores “N.”
Next, component addition processing by the management computer 100 will be explained. Firstly, the entire processing will be explained with reference to
Firstly, the details of the configuration information acquisition processing in step S13 will be explained. The configuration information acquisition processing for adding a node or a component to a device management group or a job management group is executed by the configuration information acquisition unit 111. The configuration information acquisition unit 111 firstly executes element addition processing A for adding an element to a group as illustrated in
The configuration information acquisition unit 111 selects a group as input by the user (S101). Then, a member addition button is selected as input by the user (S102) and node N and component C of the node, which are targets to be added to the group selected in step S101, are selected (S103).
Then, the configuration information acquisition unit 111 receives node N and component C which are elements to be added to group G selected in step S103 (S104). Subsequently, the configuration information acquisition unit 111 registers the group ID of group G, the node ID of node N, and the component ID of component C in the group member table 604 (S105).
Then, the configuration information acquisition unit 111 judges whether the value of component C registered in step S105 is set or not (S106). If it is determined in step S105 that the value of component C is set, the configuration information acquisition unit 111 executes element addition processing B for adding the element to a group (S107). On the other hand, if it is determined in step S105 that the value of component C is not set, the relevant element is not the component and the configuration information acquisition unit 111 terminates the element addition processing A.
The element addition processing B in step S107 is processing for adding a base component to the added component when the component is added to the relevant group by the element addition processing A. The base component is added to each group based on the base component addition rule definition table 606.
The configuration information acquisition unit 111 receives information about the element to be added to the group (S121) as illustrated in
Subsequently, the configuration information acquisition unit 111 judges whether the parent path received in step S121 includes its own component ID or not (S122). Furthermore, in step S122, the configuration information acquisition unit 111 judges whether or not the component status management table 605 includes those matching the received group ID, node ID, and component ID.
If it is determined in step S122 that the parent path includes its own component ID, the configuration information acquisition unit 111 terminates the element addition processing B. On the other hand, if it is determined in step S122 that the parent path does not include its own component ID, the configuration information acquisition unit 111 updates the component information management table (S123). Specifically speaking, the configuration information acquisition unit 111 stores the information received in step S121 about the elements to be added to the group (the group (GID), the node (NID), the component (CID), the parent path or the quantification quantifier) in the component status management table 605.
Subsequently, the configuration information acquisition unit 111 loops the processing from step S124 to step S133 with respect to each row R of the base component addition rule definition table 606.
The configuration information acquisition unit 111 judges whether the component type of component CID stored in the component status management table 605 in step S123 matches the component type of row R (S125). The component type of the component CID can be acquired by referring to the component table 602. For example, the component table 602 shows that the component type of the node “Storage 1” and the component “Volume 1” is “STORAGE_VOLUME.” Then, the configuration information acquisition unit 111 judges whether or not there is any component type, which matches this component type (STORAGE_VOLUME), in the base component addition rule definition table 606.
If it is determined in step S125 that there is a matching component type, the configuration information acquisition unit 111 loops the processing from step S126 to step S132. On the other hand, if it is determined in step S125 that there is no matching component type, the configuration information acquisition unit 111 terminates the loop processing from step S126 to step S132.
The configuration information acquisition unit 111 loops the processing from step S127 to step S132 with respect to each row C of the component relation table 603.
Firstly, the configuration information acquisition unit 111 judges whether the search method which is the rule for the target row R of the base component addition rule definition table 606 is “Order” or “Reverse” (S127). If the search method is “Order” in step S127, the configuration information acquisition unit 111 executes processing in step S128 and subsequent steps from the left to the right of the tree structure of the group. On the other hand, if the search method is “Reverse” in step S127, the configuration information acquisition unit 111 executes processing in step S129 and subsequent steps from the right to the left of the tree structure of the group.
In step S128, the configuration information acquisition unit 111 judges whether or not the component type and relationship of the component relation table which matches the target component ID are the same as the component type and relationship of the base component addition rule definition table 606 (S128). If they match each other in step S128, the configuration information acquisition unit 111 executes the element addition processing B (S130). In step S130, the configuration information acquisition unit 111 recursively calls the element addition processing B by specifying the group ID, the node ID, the related component ID, the parent path, and the quantification quantifier as information about the element to be added to the group.
In step S129, the configuration information acquisition unit 111 judges whether or not the component type and relationship of the component relation table which matches the target component ID are the same as the component type and relationship of the base component addition rule definition table 606 (S129). If they match each other in step S129, the configuration information acquisition unit 111 executes the element addition processing B (S131). In step S131, the configuration information acquisition unit 111 recursively calls the element addition processing B by specifying the group ID, the node ID, the related component ID, the parent path, and the quantification quantifier as information about the element to be added to the group.
For example, assuming that Volume 1 is added to a “Business” group by the user, “Business, Storage 1, Volume 1, /, -” is received in step S121. Then, since the parent path is “/,” “NO” is selected as the judgment for step S122. Then, (Business, Storage 1, Volume 1, /, -) is stored in the component status management table 605 in step S123.
Furthermore, reference is made to the rule ID=1 of the base component addition rule definition table 606 in step S125. Since the component type “STORAGE_VOLUME” of the rule ID=1 matches the component type “STORAGE_VOLUME” in the component status management table 605, “YES” is selected for the judgment of step S125. Then, since the search method for the rule ID=1 is “Order,” the judgment of step S128 is performed. In step S128, whether the component ID of the component relation table 603 matches the component ID of the base component addition rule definition table 606 or not, whether the related component type matches the additional component type or not, and whether the relationships match each other or not are judged. Since the component ID is Volume 1, the component type is “STORAGE— VOLUME,” and the relationship is “Depend,” and they match each other, “Business, Storage 1, Parity Group 1, /Volume 1, Any” is delivered to the group element addition processing B in step S130.
Then, as “Business, Storage 1, Parity Group 1, /Volume 1, Any” is received in step S121, “Parity Group” is not included in the parent path “/Volume 1” in step S122, and the component status management table 605 does not include any matching GID, NID, or CID, “NO” is selected for the judgment. Then, in step S123, “Business, Storage 1, Parity Group 1, /Volume 1, Any” is stored in the component status management table 605.
The element addition processing B is repeated by referring to the base component addition rule definition table 606 and the component relation table 603 as described above until no more base component to be added to the management group is found, thereby updating the component status management table 605.
Next, the details of the status update processing in step S14 of
Firstly, the status and performance information acquisition unit 112 acquires the status information about components constituting node N from node N and updates the status information about the components regarding node N in the component table 602 (S22).
Then, the status and performance information acquisition unit 112 sets the worst value of the status of the same node N in the component table 602 to the node table 601 as the status information about node N.
Next, the status and performance information acquisition unit 112 loops the status update processing A in step S26 on each row GM of the group member table 604 (S26). If the loop processing in step S26 is completed (S27), the status and performance information acquisition unit 112 terminates the status and performance information processing.
The status update processing A in step S26 will be explained. The status and performance information acquisition unit 112 receives information about a member added to a group as illustrated in
Then, the status and performance information acquisition unit 112 judges whether the component ID (CID), among the member information received in step S201, is a null value or not (S202). If the component ID is a null value in step S202, it means that the element added to the group is a node. In other words, whether the element to be added to the group is a node or a component is judged in step S202.
If it is determined in step S202 that the component ID (CID) is a null value, the status and performance information acquisition unit 112 terminates the status update processing A. On the other hand, if it is determined in step S202 that the component ID (CID) is not a null value, the status and performance information acquisition unit 112 executes the status update processing B (S203). In other words, if the element to be added to the group is a component, the status and performance information acquisition unit 112 executes the processing for recognizing the status of base component of that component (the status update processing B).
The status and performance information acquisition unit 112 receives information about the element to be added to the group as illustrated in
Then, the status and performance information acquisition unit 112 loops the processing from step S213 to step S222 with respect to component C whose parent path name in the component status management table 605 is a value equivalent to “parent path/CID” received in step S211.
In step S213, the status and performance information acquisition unit 112 recursively calls the status update processing B with respect to component C of the component information management table corresponding to the parent path name “parent path/CID” after the loop processing.
Firstly, the status and performance information acquisition unit 112 refers to the component status management table 605 and judges the quantification quantifier of component C (S214). If the quantification quantifier of component C is “Any” in step S214, the status and performance information acquisition unit 112 executes processing in step S215 and subsequent steps. On the other hand, if the quantification quantifier of component C is “All” in step S214, the status and performance information acquisition unit 112 executes step S216 and subsequent steps.
In step S215, the status and performance information acquisition unit 112 acquires element W with matching My Path and rule from a work table 607 illustrated in
The work table 607 is a work table temporarily stored in the storage device of the management computer 100. The work table 607 is constituted from a My Path column 6071, a rule ID column 6072, and a value column 6073 as illustrated in
If it is determined in step S217 that element W exists in the work table 607, the status and performance information acquisition unit 112 compares the status of the target component with the value of the work table and updates the value of the value column 6073 in the work table 607 with the worse value.
On the other hand, if it is determined in step S217 that element W does not exist in the work table 607, the status and performance information acquisition unit 112 registers element W in the work table 607 (S219). Specifically speaking, the status and performance information acquisition unit 112 stores the value of the parent path name column 605 of the target component of the component status management table 605 in the My Path column 6071 of the work table 607. The status and performance information acquisition unit 112 also stores the value of the rule ID column 6054 of the component status management table 605 in the rule ID column 6072 of the work table 607. Moreover, the status and performance information acquisition unit 112 stores the value of the status column 6059 of the component status management table 605 in the value column 6073 of the work table 607.
Furthermore, in step S216, the status and performance information acquisition unit 112 acquires element W with matching My Path and rule from the work table 607 illustrated in
If it is determined in step S218 that element W exists in the work table 607, the status and performance information acquisition unit 112 compares the status of the target component with the value of the work table and updates the value of the value column 6073 in the work table 607 with the worse value.
On the other hand, if it is determined in step S218 that element W does not exist in the work table 607, the status and performance information acquisition unit 112 registers element W in the work table 607 (S219).
After the loop processing from step S212 to step S222 is completed, the status and performance information acquisition unit 112 sets the worst value of values in each row, whose value of the My Path column 6071 of the work table 607 matches the “parent path/component ID,” as a value of the base component status (S223). Specifically speaking, the status and performance information acquisition unit 112 stores the worst value of values in each row, whose value of the My Path column 6071 of the work table 607 matches the “parent path/component ID,” in the base component status column 6058 of a row which matches the group ID, the node ID, and the component ID in the component status management table 605.
Then, the status and performance information acquisition unit 112 deletes the row whose My Path matches the “parent path/CID” from the work table 607 (S224).
For example, if information about the element of the management group “Business, Storage 1, Volume 1, /” is received in step S211, the processing from step S212 to step S222 is looped with respect to “Parity Group 1” having the same “parent path name” value as the parent path / component ID “/Volume 1” in the component status management table 605. Furthermore, the processing from step S212 to step S222 is looped with respect to “Power Unit 1” having the same “parent path name” value as “/Volume 1/Parity Group 1.” As a result of the above-described loop processing, it is possible to store the status of all the base components of the component, the status of the component itself, and the general status of the component in consideration of the status of all the base components in the component status management table 605.
Next, display processing by the management computer 100 will be explained. The display processing for displaying the status information about nodes and components of a device management group or a job management group on the display computer 200 is executed by the display unit 114.
Group display processing will be firstly explained. The display unit 114 receives group selection information (group ID: GID) as input by the user (S301).
Then, the display unit 114 executes loop processing from step S302 to step S306 on an element group member (GM) in the group member table 604, which matches the group ID received in step S301.
The display unit 114 firstly judges whether the member component ID column 6043 of the group member table 604 is a null value or not (S303). If the member component ID column 6043 is a null value, it means that the member element is a node.
If it is determined in step S303 that the member component ID column 6043 is a null value, the display unit 114 acquires row N of the node table 601, which matches the value of the member node ID column 6042 in the group member table 604, and displays the value of the status column 6013 of row N in a status column and a general (Status) column of a display screen (S304).
On the other hand, if it is determined in step S303 that the member component ID column 6043 is not a null value, the display unit 114 acquires row C of the component status management table 605, which matches the group ID, the group member node ID, the group member component ID, and “/,” and displays the acquired information on the display screen (S305).
Next, group member display processing will be explained. The display unit 114 receives member selection information as input by the user as illustrated in
Then, the display unit 114 judges whether the content ID (CID), among the information received in step S311, is a null value or not (S312). If the content ID is a null value, it means that the element is a node.
If it is determined in step S312 that the content ID (CID) is a null value, the display unit 114 executes loop processing from step S313 to step S315 with respect to component C with the node ID selected by the user.
The display unit 114 displays the status information of component C of the component table 602 of the selected component in the general status column and the status column on the display screen (S314).
On the other hand, if it is determined in step S312 that the component ID (CID) is not a null value, the display unit 114 executes base component expansion display processing on the target component (S316).
The details of the base component expansion display processing in step S316 described above will be explained. The display unit 114 receives the component selection information (the group ID, the node ID, the component ID, and the parent path) selected as input by the user (S321).
Then, the display unit 114 loops the processing in step S323 with respect to row F whose group ID and node ID in the component status management table 605 match each other and whose parent path is identical to the “parent path/CID.”
In step S323, the display unit 114 displays the status information, which is stored in the general column 6057, the base component status column 6058, and the status column 6059 of row F of the component status management table 605, as the general status, the status of the base component, and the status respectively on the display screen.
Next, the content of the display screen by the above-described display processing by the display unit 114 will be explained.
For example, if “Business” which is a job management group is selected by the user from among the resource groups (RG) on the component display screen 500 illustrated in
Furthermore, if “Storage 1/Volume 1” is selected on the component display screen 500 in
Furthermore, if “Device” which is a device management group is selected by the user from among the resource groups (RG) as illustrated in
Furthermore, if “Storage 1” is selected on the component display screen 520 in
Accordingly, the status of components can be changed and displayed depending on the status of the administrator such as the job administrator or the device administrator. For example, the component display screen 510 in
(5) Advantageous Effects of this Embodiment
According to this embodiment, when a node (monitoring target device) or a component is added to a job management group or a device management group (monitoring target group) as input by the job administrator or the device administrator and a failure occurs at a base component of the component: and if the status of the component is to be displayed via the monitoring target group, information indicating that the component is in a critical state is displayed; and if the status of the component is to be displayed without intermediary of the monitoring target group, information indicating that the component is in a normal state and the node or the base component is in a critical state is displayed. As a result, it is possible to efficiently recognize influences on the management target at the time of the occurrence of a failure by specifying a device related to the management target of the administrator and elements constituting the device and providing the status information about the management target in consideration of the status of the above-mentioned related device and elements.
