Abstract
A network management application provides notification of events on network devices using prepopulated notification rules. The notification rule is prepopulated by the network management application using conditions that represent the present state of the device being monitored. An associated notification action is executed when an event on a network device satisfies the conditions of the prepopulated notification rule. The notification action can be tested without actually creating a set of conditions for a device that satisfies the conditions of the notification rule.

BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to computer network management and more particularly to automatically defining conditions under which a user is notified of network activity.




2. Description of the Related Art




Network management has experienced explosive growth and become a fundamental part of network infrastructure. Network management is essentially a set of tools and processes that enables one to control, monitor, and troubleshoot a network. A network manager typically uses standalone or integrated network management software to collect and process management data from the network.




One of the functions served by network management software is the monitoring (or health polling) and notification of the state of various network devices. The state of a monitored device is reported, for example, as an entry in an event log dialog. As the use of network systems has grown, so too has the size of the networks. As such, many network systems are very complex. Likewise, network management for these large systems can be very complex. To provide a manageable interface, the network management software may be configured to report only changes in the state of a device. To further streamline reporting performed by network management software, a notification rule may be created to report only certain instances or severities of particular network changes.




A notification rule is a description of a type of event, or set of conditions, that triggers a notification. The notification rule tells the network management software when to notify a user or an administrator of an event. Generally, a notification rule is defined by a set of conditions relating to the device being monitored. These conditions may describe the present state of a device. Some event information that has been used to define notification rules are device types, alarm event types and alarm severity classes.




For example, a notification rule can be based in whole or in part on an alarm threshold condition to indicate when a network device, monitored by the network management software, exceeds or exits a certain operating state for that device. A rule for a network router device can be triggered using an alarm threshold set for monitoring the number of dropped or lost data packets. The alarm and subsequently the notification rule, is triggered when the number of dropped data packets exceeds the preset threshold. In addition, a corresponding alarm severity class can be set to limit triggering of the notification rule based on the extent to which the threshold had been exceeded. Alarm severity classes, for example, have included cleared (or informational), indeterminate, minor, major and critical alarm classes. For example, a number of dropped data packets only slightly exceeding the alarm event threshold is represented by a “minor” alarm, while a number of dropped data packets greatly exceeding the threshold is represented by a “critical” alarm. In addition, an “informational” alarm severity class has been established to provide information for devices not exceeding normal operating conditions.




Typically these notification rules have been created by a user or a network administrator. Much like the network systems they were designed to monitor, the notification rules have become increasing complex. Specifically, the user must step through a number of procedures to properly configure a notification rule for a particular device or a particular state of a device. Specifically, each of the event conditions included in a notification rule required that a user first retrieve the information describing the condition from somewhere within the network management software application. Next the user was required to manually enter in the relevant information into the notification rule. Finally, to complete the notification process, the user was required to specify a particular notification action that would be performed when the conditions defining the notification rule had been satisfied.




To further complicate the process, a number of alarm event and alarm severity combinations can be used. Typically, the combination of conditions for a particular notification rule was selected by taking the present state of a device. Specifically, the network management software would indicate the occurrence of an event for a device on the network and display such on a monitor at its location on the network server. An administrator then would typically desire that he be notified in the future upon subsequent like changes in the state of that particular device. Therefore, the notification rule would be created based on the set of conditions defining the state of the device in question.




The notification rule would include, a notification action specified by the administrator. These notifications actions included, for example, executing a script at the server location, reporting the particular event occurrence on a separate event log saved in the network management software, indicating a change in the state of the device by creating a sound on the host computer, sending an e-mail to a remote e-mail address, and sending a page to a remote receiver, for example the administrator's pager. Any of these notification actions, or any combination thereof, would be performed by the network management software when the state of the monitored device matched the particular state upon which the notification rule conditions were based.




Configuring notification rules was time consuming, requiring a user or an administrator to manually configure all the information needed to define the notification rule. In addition, the administrator was usually left with no real way to test the specified notification action. In this way, upon creation of a notification rule, an administrator was unable to test the action without actually causing the event conditions that triggered the notification action to occur. A network administrator was, forced to either skip testing the notification to see if its effect is what is intended, or forced to attempt to create the event artificially to test the notification. Under many critical situations, creating an actual network problem may be undesirable from a systems standpoint, if not altogether impossible.




SUMMARY OF THE INVENTION




A system according to the present invention provides automatic notification of an event caused by a change in the state of a device connected to a network. A device, such as a network server, is monitored for activity. The present state, at any given time, is reported to a network management application. The application executes a notification action when the device activity satisfies a set of predetermined conditions, collectively termed a notification rule.




A system according to the present invention allows automatic prepopulating of the conditions comprising notification rule with the present state or set of conditions of a network device, as reported by the monitoring function. This simplified procedure avoids time-consuming manual searching of present device conditions and subsequent manual entry of these conditions into a notification rule. The notification rule functions as the trigger mechanism for a notification action. The notification action reports the occurrence of the event to the user in a manner specified by the user.




In addition, the present invention allows the notification feature to be easily tested by simulating the trigger for the notification action. The testing capability is performed without actually creating an event on the monitored device to trigger the conditions of the notification rule.

FIG. 1

illustrates a network management system according to the invention. The system N allows an administrator


20


to receive notifications that report the present state of a particular network device


18


. The network devices


18


are monitored via network interconnections


16


by a network management software


14


residing in the memory


12


of a host computer system


10


. The network management software


14


most generally monitors the status of the various network devices


18


connected to the network. In addition, however, network management software


14


is capable of receiving requests from the network and responding thereto. The network management software


14


is further capable of receiving and responding to requests from a network administrator


20


. Specifically, an administrator


20


is able to configure the notification function provided by the management software to limit notification, or device status reporting, to only those instances in which a network event occurs. Most generally, a network event represents a change in status of a device being monitored. Therefore, the administrator


20


is able to request the network management software


14


to execute a notification action only when a preselected event occurs. To achieve this notification for specific network occurrences, the network administrator


20


configures the network management software


14


by defining a set of event conditions that describe the particular state upon which notification will occur. Therefore, the network management software


14


allows the user or network administrator


20


to receive notification of certain preselected events that occur on the network. Specifically, these events are tied to network devices. The trigger that causes a notification to take place is generally called a “notification rule.”




The action performed when a notification rule is triggered is called a “notification action.” Examples of notification actions may be paging a users pager, sending email, playing sounds or beeps on a speaker, or logging event messages to a network log, on the network management software. The particular notification action, or combination of notification actions, is typically specified by the administrator.




Turning now to

FIG. 2

, shown is a more detailed block diagram of a network management application as shown in FIG.


1


. Specifically,

FIG. 2

illustrates both the creation of a notification rule and the testing of a notification action. The notification rule


206


is part of the network management software


14


and defines when the network management software


14


will execute a notification action associated with a particular event occurring on the network. Triggering the notification rule


206


triggers the user specified notification action


210


.




Typically, a notification rule


206


is defined by a set of event conditions on a particular device. Typically, these event conditions include the device identification of the device on which the notification rule


206


is to be based, the type of event that triggers the rule and the severity of those events necessary to trigger the rule. A previous event in an event log in the network management software


14


, through its monitoring of a network device


18


, already contains all of this information. The network management software


14


is thus able to automatically prepopulate the various conditions, or fields, of the notification rule


206


when that notification rule is derived from an existing event or device condition. In this way, creation of a notification rule


206


does not require the administrator


20


to first “look up” or consult the network management software (path (


1


)) and then to transpose this information into the notification rule


206


(path (


2


)). Instead, upon an administrator


20


request to create a notification rule for a particular device, the network management software


14


through its normal monitoring of present device states for all network devices, automatically prepopulates the fields of the new notification rule


206


with the present state of the preselected network device or with a device state of an entry stored in an event log. Prepopulating the notification rule


206


is discussed in more detail below with reference to

FIGS. 4-6

.




A reference to a notification action to be performed upon triggering of the notification rule


206


is also included in creation of a notification rule. Specifically, when the set of event conditions describing the present state of the device satisfies the set of predetermined conditions defined by the notification rule, the notification rule causes the preselected notification action to be taken. In addition, the notification action


210


may be tested via the test mode


212


. The test mode


212


causes the notification action


210


to be performed by automatically simulating satisfaction of the set of predetermined conditions defined by the notification rule. The test mode


212


is discussed in more detail below with respect to

FIGS. 7 and 8

.




Turning now to

FIG. 3

shown is a flow diagram for automatically prepopulating a new notification rule and testing a specified notification action. As part of normal operation network management software


14


, monitors the present state for each of the network devices


18


connected to the network N a stop


302


. The Create New Notification Rule function


306


is then initiated after the administrator


20


requests that the network management software


14


create a new notification rule for the selected device


304


. A common circumstance under which a user may request creation of a new notification rule is where the network management software, through its device monitoring, displays or otherwise indicates on the host computer system


10


that a change in the state of a network device has occurred. Such a occurrence, for example, may be indicated by a change in the color of a icon representing the state of the particular network device. Typically, the administrator will then wish to track or otherwise be notified of subsequent like changes in the device state. In this instance, the notification rule


206


is based on the event conditions that describe the state presently monitored by the network management software


14


.




An administrator may also wish to be notified of subsequent occurrences of a particular alarm or error for a particular device. Specifically, after the network manager detects an alarm or an error for a network device, the administrator can create a new notification rule that is based on the conditions that define the particular alarm detected by the network management monitoring function. Subsequent occurrences of that same alarm for the selected device will then trigger the notification rule causing the specified notification action to be performed.




In a like manner, a new notification rule may be based on the conditions that define a particular alarm or an event stored in an event log. In such an instance, the conditions for the new notification rule are taken from the conditions of a preexisting event or alarm contained in a entry in the event log.




Once a new notification rule is requested, the new notification rule is then prepopulated with a set of conditions representing the specified state of a monitored network device, such as the present state, a specified alarm state or a prior state stored on an event log. The prepopulation feature will be discussed in more detail below with reference of FIG.


4


. At step


308


the administrator can make modifications to the rule. For example, the administrator can modify one of those fields prepopulated by the Create New Notification Rule function


306


. The function continues at step


310


by requesting a particular notification action from the user to be performed upon triggering of the notification rule. Specifically, the notification action will be performed when the set of event conditions representing the present state of the monitored device satisfies the predetermined conditions defined by the notification rule for that device.




At step


310


, the notification action may be created as a new action or may be selected from a list of preexisting notification actions. For example, according to one embodiment of the present invention, an action table can store in memory a number of user created notification actions. Within the notification rule, an administrator or user is able to select one of these predefined actions. The notification rule is then assigned a pointer to that action in the action table.




At step


312


, it is determined whether the user or administrator has selected the test mode


212


to test the notification action. According to one embodiment, the notification action may be tested either when the notification action is first created or later edited. Alternatively, the notification action may be tested at any time after the action has been created. The test function


314


will be discussed in more detail below with reference to FIG.


7


.




The notification rule is then saved at step


316


after the test mode


212


, if selected, has tested the notification action. If the test mode


212


has not been selected , the notification rule is saved without calling the test function


314


. The function returns to the calling function at step


318


.




Turning now to

FIG. 4

, shown is a flow diagram for the Create New Notification Rule function


306


according to one embodiment of the present invention. The Create New Notification Rule


306


begins by retrieving from the network management software


14


the device ID for the monitored device


404


, the alarm severity


406


, and the alarm event type for the monitored device


408


. As mentioned above, when the notification rule


306


is based on the present state of a selected device, this information is already known by the network management software


14


via its normal operation of monitoring the present states of network devices. Further, this retrieval is performed internally and automatically without user assistance. Specifically, once an administrator


20


requests that a new notification rule be created for a particular device, the set of event conditions known by the network management software


14


pertaining to the present state of the selected device is retrieved by the Create New Notification Rule function


306


. It should be understood that while alarm severity conditions and an alarm event type conditions are used for exemplary purposes to create the new notification rule, other conditions that relate to the state of the device on the network may be retrieved and subsequently prepopulated. Furthermore, although a device ID is used for exemplary purposes, the notification rule may be defined to key off of a group or class of devices. For example, a device map can be used to define a class of devices that are associated in some way. In addition, a device type can be used to define a class of devices that share a common characteristics, for example all routers.




The Create New Notification Rule


306


continues at step


410


by creating a new blank rule. The conditions retrieved from the network management software


14


are then populated into the new blank rule at step


412


. At this point, the conditions known by the network management software are also contained in the new notification rule for the selected device. At step


414


the create new notification rule


306


returns to its calling function.




Turning now to

FIG. 5

, shown is an exemplary implementation for automatically creating a new notification rule according to one embodiment of the present invention. Specifically, the administrator


20


selects a network device


552


, monitored by the network management software


14


, by clicking the right button on a mouse device connected to the host system


10


. In so doing, a notification feature may be selected from a menu of options


554


. The notification option further contains the options of either creating a new notification rule or editing an existing a device notification rule


556


.




Once the administrator


20


has requested the network management software


14


to create a new notification rule for a particular device, the create new notification dialog window appears with the prepopulated information preselected.

FIG. 6

shows an exemplary create new notification dialog


600


for one embodiment of the present invention. Upon an administrator request to create a new notification rule for a selected device


552


, the event information for the selected device


552


, including the device identification


602


, the event class information


604


, and the alarm severity information


606


is automatically prepopulated into the dialog


600


.




In this case, the administrator


30


has selected the device identified by “Fiber 1:198.100.1.47” 552. According to one embodiment of the present invention, this is done by right clicking a mouse device on the icon corresponding to that device in the main network management display from FIG.


5


. The event class information


604


and the alarm severity information


606


prepopulated or loaded into the notification rule dialog


600


describes the state of the device monitored by the network management software


14


at the time the user selected the device. In this way, the administrator is saved the trouble of manually filling in redundant information that the network management software already knows. All the information that is already known by the network management software is automatically prepopulated into the notification rule dialog at the time the user requests that a new notification rule be created. Specifically, when a notification rule is based on a set of conditions describing the present state of a device, the administrator is not required to first track down the event conditions defining the present state of the device and second to then transpose this information into the create new notification dialog


600


. All that remains for the administrator is to specify the particular notification action


608


to be performed when the conditions of the notification rule are satisfied.




Turning now to

FIG. 7

, shown is a flow diagram of the test function


314


. The test function begins by first retrieving at step


504


and validating at step


506


the notification action information entered by the administrator or user. In the event the test function


314


detects erroneous notification action information at step


508


, the function informs the user of the erroneous entry at step


510


and then returns to the main function at step


310


. Although for exemplary purposes, the validation process is part of the test mode function, the validation process may be performed independent of selection of the test mode. Specifically, according to one embodiment of the present invention, this validation process is performed for every notification action upon its creation or modification.




In the event the notification action information is okay at step


508


, the test function calls the corresponding function to perform the selected action


512


. Although a number of actions may be selected, for exemplary purposes a notification action may cause a predefined script to be executed


514


, may result in an audible sound


516


, the network management software may send a page to a pager


518


, or may log the particular event in an event log


552


and may send an e-mail to an email address


520


. It will be understood that these actions are common actions for notifying a user of any number of different occurrences in a computer system and implementation thereof will be understood by one skilled in the art. In addition, the notification action may result in an combination of a number of notification actions. When all actions have been performed, the test mode function


314


returns to the calling function at step


526


.




Turning now to

FIGS. 8A and 8B

, shown are exemplary implementations of the test mode function


314


.

FIG. 8A

illustrates an exemplary screen shot of the notification action dialog


800


according to one embodiment of the present invention. The notification action dialog


800


illustrates the various options of notification actions available. Examples of the notification actions performed by the network management software


14


may be the execution of a predefined script


802


, logging the event in an event log


804


, creating an audible noise


806


, sending an e-mail to an email address


808


, or paging a pager


810


. Further included in the notification action dialog


800


is a test button


812


for initiating the test mode feature. By clicking on the test button using a mouse device, an administrator or user is able to test the selected notification action or actions by simulating satisfaction of the notification rule. Therefore, notification is performed without requiring the user to actually recreate or emulate the set of event conditions that trigger the notification rule. In this way, according to one embodiment of the present invention, testing of the notification action is performed without actually triggering the notification rule. Although, for exemplary purposes, simulating satisfaction of the notification rule is accomplished by the test mode directly calling those functions that direct the host computer to perform the specified action, the notification action may be tested using other methods of simulating satisfaction of the conditions of the notification rule. Specifically, testing may be accomplished by supplying the notification rule with artificial input conditions that satisfy the predetermined conditions defined in the notification rule. In this way, the notification action is tested directly by the notification rule but without creating an actual network event to satisfy the conditions of the notification rule. Satisfaction of the condition of the notification rule is simulated.




Using the notification item


822


from the notification action log dialog window


820


shown in

FIG. 8B

, an exemplary test mode application will be described. Specifically, the action named “wreak havoc”


822


lists a number of notification actions to be performed upon satisfaction of the set of event conditions defined by the appropriate notification rule. However, the test button


812


initiates the test mode feature to test the specified notification actions by simulating satisfaction of the conditions defined in the notification rule. According to one embodiment, the notification action is executed without triggering the conditions of the notification rule. According to another embodiment, the notification action is performed when the conditions of the notification rule have been triggered but without recreating the network event defined by the event conditions. Using the wreak havoc example, triggering of the notification rule causes the detected event to first be logged in an event log, typically controlled by the network management software, will cause a user defined script to be executed and will cause an audible noise of three beeps at 2,000 Hz frequency to be played. These notification actions will be performed in one of two ways. First, triggering of the notification rule to which the notification action wreak havoc is assigned will cause each of the notification actions specified to be performed. Triggering of the notification rule occurs when a network event takes place that matches the event defined by the notification rule. Second, the notification action specified may be tested using the test mode which merely simulates satisfaction of the notification rule. Therefore, testing of the notification action specified by the user does not require that the user create an event that satisfies the conditions defined in the notification rule.




Further, the creation of a notification rule does not require an administrator to manually configure all the information needed to define the notification rule. Such manual configuration is both time consuming, error prone and redundant since all the information is already available to the network management software. Specifically, the notification rule is prepopulated with the information that is already known by the network management software for a selected device. Therefore, a notification rule is automatically created when the administrator right clicks on a mouse device on a icon corresponding to the device at issue.




The foregoing disclosure and description of the preferred embodiment are illustrative and explanatory thereof, and various changes in the number of variables, number of parameters, order of steps, field sizes, data types, code elements, code size, connections, components, color object types, and circuitry, as well as in the details of the illustrated hardware and software and construction and method of operation may be made without departing from the spirit of the invention.
