Client-side monitoring tools collect data from an application at the client side and send that data to a server for analysis. The breadth and depth of information collected by a client-side monitoring tool may be limited due to the amount of bandwidth consumed by the tool, the toll that the tool takes on the battery life of the client device and/or on other ways in which the tool negatively impacts the performance of the client device.
The following detailed description references the drawings, wherein:
The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several examples are described in this document, modifications, adaptations, and other implementations are possible. Accordingly, the following detailed description does not limit the disclosed examples. Instead, the proper scope of the disclosed examples may be defined by the appended claims.
As detailed above, application owners, application developers, and other interested parties often want to analyze their application. To that end, these parties often rely on client-side monitoring tools to collect data from an application at the client side and send that data to a server for analysis. Example monitoring tools may collect all traffic and data being processed in relation to an application and pass the collected information to a server for analysis. The data collected by a monitoring tool may be identical across client devices for a particular application. For instance, an example monitoring tool may collect the same information from an application running on a first client device as from a second client device. The type and amount of data may be restricted, as mentioned above, based on the amount of bandwidth consuming by the example monitoring tool, the battery life toll of the example monitoring tool, and/or other issues related to the tool.
Example embodiments disclosed herein address these issues by instrumenting an application running on a client device to monitor application flow of that application. Upon launch of a new session of the application, the client device may request a monitoring mode from a server and may monitor application flow based on the received monitoring mode. The server may be a predetermined server made available by the application, a server from which the application was procured, and/or another server communicably coupled to the client device via the application.
The monitoring mode may be one of several monitoring modes. For example, the monitoring mode may be a regular mode, an extended mode, and/or other monitoring mode. The regular mode may be a default mode by which application flow is monitored. The extended mode may be a special mode by which application flow is monitored. For example, the extended mode may be customized such that the extended mode is entered based on one or more predetermined conditions being met. In another example, the extended mode may be entered based on random selection by the server of a client device requesting a mode indication.
The client device may monitor application flow based on the received mode from the server. The client device may send information related to the application flow to the server, which may then analyze the received information to determine and optimize user experience.
Referring now to the drawings,
Processor 120 may be one or more central processing units (CPUs), microprocessors, and/or other hardware devices suitable for retrieval and execution of instructions stored in machine-readable storage medium 110. Processor 120 may fetch, decode, and execute program instructions 112, 113, and/or other instructions to enable monitoring of applications running on the client computing device 100, as described below. As an alternative or in addition to retrieving and executing instructions, processor 110 may include one or more electronic circuits comprising a number of electronic components for performing the functionality of one or more of instructions 112, 113, and/or other instructions.
In one example, the program instructions 112, 113, and/or other instructions can be part of an installation package that can be executed by processor 120 to implement the functionality described herein. In this case, memory 110 may be a portable medium such as a CD, DVD, or flash drive or a memory maintained by the server computing device 200 from which the installation package can be downloaded and installed. In another example, the program instructions may be part of an application or applications already installed on client computing device 100.
Machine-readable storage medium 110 may be any hardware storage device for maintaining data accessible to client computing device 100. For example, machine-readable storage medium 110 may include one or more hard disk drives, solid state drives, tape drives, and/or any other storage devices. The storage devices may be located in client computing device 100 and/or in another device in communication with server 200. As detailed below, storage medium 110 may maintain and/or store the data and information described herein.
For example, machine-readable storage medium 110 may be any electronic, magnetic, optical, or other physical storage device that stores executable instructions. Thus, machine-readable storage medium 110 may be, for example, Random Access Memory (RAM), an Electrically-Erasable Programmable Read-Only Memory (EEPROM), a storage drive, an optical disc, and the like. As described in detail below, machine-readable storage medium 110 may be encoded with executable instructions for monitoring application flow to determine user experience of an application.
Machine-readable storage medium 110 may store mode information 111, described in further detail below. The mode information may be used by the client computing device 100 to monitor applications running on the client computing device 100.
Mode determination instructions 112, when executed by processor 120, may determine a monitoring mode by which the application flow of an application may be monitored. The mode determination instructions 112, when executed by processor 120, may determine a monitoring mode by requesting a monitoring mode from a server communicably coupled to the client computing device 100. For example, the mode determination instructions 112, when executed by processor 120, may request a monitoring mode from the server responsive to a new session of the application being launched.
In some examples, the request to the server 200 may comprise information related to previous application flow information monitored by the client computing device 100. In some examples, the request to the server may include state data of the application, characteristics of the application, characteristics of the client computing device 100, and/or other information relating to the application running on the client computing device 100.
Responsive to requesting the monitoring mode, the mode determination instructions 112, when executed by processor 120, may receive an indication of a monitoring mode. The indication of the monitoring mode may comprise, for example, an indication to monitor the application in regular mode, an indication to monitor the application in extended mode, and/or another type of indication related to monitoring the application.
In some examples, the mode determination instructions 112, when executed by processor 120, may receive information related to how to monitor application flow in the manner of the indicated monitoring mode. For example, the mode determination instructions 112, when executed by processor 120, may also receive current mode information, and/or other information related to monitoring application flow from the server. Mode information 111, as described in further detail below, may comprise information related to each of the modes by which the application may be monitored, as well as parameters to monitor for an individual mode, conditions based on which a monitoring mode may be determined, and/or other information related to monitoring modes.
Type of monitoring modes may include, for example, a regular mode, an extended mode, and/or other mode by which application flow of an application may be monitored. A regular mode may be a default mode by which application flow of an application is monitored. An extended mode may be a special mode by which application flow of an application is monitored. The extended mode may be used responsive to the client computing device 100 determining that the application flow of the application should be monitored in an extended mode. Other modes may be used responsive to determining that another mode should be used.
Monitoring an application in extended mode may comprise obtaining different information than the information obtained by monitoring an application in standard mode. For example, monitoring an application in extended mode may comprise obtaining additional information along with the information obtained by monitoring an application in standard mode. In another example, the amount of information obtained by monitoring an application in extended mode and standard mode may be the same, but the information monitored may be different. In some examples, monitoring an application in extended mode may obtain more depth of information in a certain area and less depth of information in another area as compared to monitoring an application in standard mode.
In some examples responsive to receiving current mode information from the server computing device 200, the mode determination instructions 112, when executed by processor 120, may store the current mode information. The mode determination instructions 112, when executed by processor 120, may use the current mode information to determine whether to monitor an application associated with the current mode information in regular mode, extended mode, and/or another mode. In some of these examples, the mode determination instructions 112, when executed by processor 120, may determine the mode by which to monitor the application and check the determined mode against the indicated mode received by the server computing device 200. In some of these examples, the server computing device 200 may send the current mode information but may not send the indication of a monitoring mode. In these examples, the mode determination instructions 112, when executed by processor 120, may use the determined monitoring mode as the monitoring mode by which to monitor the application.
Application monitoring instructions 113, when executed by processor 120, may monitor the application flow of the application. The application monitoring instructions 113, when executed by processor 120, may monitor the first application responsive to receiving the indicated monitoring mode. For example, the application monitoring instructions 113, when executed by processor 120, may monitor the application in a regular mode by obtaining predetermined information related to application flow of the application, wherein the predetermined information is associated with the regular mode. In another example, the application monitoring instructions 113, when executed by processor 120, may monitor the application in an extended mode by obtaining a different predetermined set of information related to application flow of the application, wherein the different predetermined set of information may be associated with the extended mode and/or any information received with the indication to monitor the application in extended mode.
The information obtained by monitoring an application in standard mode may be based on a predetermined set of information associated with standard mode. The predetermined set of information associated with standard mode may be stored at the machine-readable storage medium 120, may be obtained from another computing device (e.g., server 200), may be obtained by an application owner and/or other interested party, and/or may be otherwise determined.
The information obtained by monitoring an application in extended mode may be determined in various ways. In some examples, there may be a default predetermined set of information associated with extended mode. In some of these examples, the default predetermined set of information associated with extended mode may be used responsive to no additional information being received with the indication of extended mode. In other examples, the information to be obtained during extended mode may be determined based on mode information 111 (as described below).
In some examples, when the mode determination instructions 112, executed by processor 120, receive an indication to monitor the application in extended mode, information related to the extended mode may also be received. Information related to the extended mode may comprise, for example, a rationale as to why the application should be monitored in extended mode, a set of conditions associated with extended mode, customer criteria associated with extended mode, mode information, and/or other information related to monitoring the application in extended mode. The application monitoring instructions 113, when executed by processor 120, may use the received information related to extended mode to determine what information to obtain during monitoring of application flow. For example, the application monitoring instructions 113, when executed by processor 120, may use the mode information to determine what information to obtain during monitoring of application flow.
In some examples, the mode information may comprise additional predetermined sets of information. For example, an additional predetermined set of information may be associated with each condition in the set of conditions based on which the application would be monitored in the extended mode. In another example, an additional predetermined set of information may be associated with each set of criteria received by a customer. A customer may be, for example, an application owner, an application developer, an entity authorized by an application owner, and/or other third party with an interest in the application being monitored.
In another example, additional predetermined sets of information may each be associated with customer criteria obtained from customers, where the application may be monitored in extended mode based on a set of customer criteria being met. The received information may include information related to a particular set of customer criteria, which may be correlated and/or otherwise associated with the additional predetermined sets of information, to determine what information to obtain during monitoring of application flow. Other ways of determining what information to obtain from the application during extended mode may also be used.
A predetermined set of information may comprise, for example, a set of parameters for which values may be obtained during monitoring of the application flow. The predetermined set of information may also comprise, for example, any other information to be obtained during monitoring of the application, time periods during which information is to be monitored, actions that precipitate the obtaining of information, and/or other information related to monitoring application flow.
The application monitoring instructions 113, when executed by processor 120, may send the obtained information (e.g., the monitored information of the application flow) to the server computing device 200. In some examples, along with the obtained information, the application monitoring instructions 113, when executed by processor 120, may send a mode indication, client computing device characteristics, application characteristics, and/or other information relevant to the running of the application on the client computing device 100. The application monitoring instructions 113, when executed by processor 120, may also store the obtained information (e.g., the monitored information) locally at the machine-readable storage medium 110).
In some examples, the application monitoring instructions 113, when executed by processor 120, may compare the information obtained during monitoring with the set of conditions, customer criteria, and/or other information based on which the application may be monitored in extended mode. Responsive to the application being monitored in regular mode and determining that the application may be monitored in extended mode based on the obtained information, the application monitoring instructions 113, when executed by processor 120, may monitor the application in extended mode, may send an indication to the server computing device 200 that the application may be monitored in extended mode, may send a request for a monitoring mode to the server computing device 200 with the obtained information, and/or may otherwise attempt to monitor the application in extended mode.
Responsive to the application being monitored in extended mode, the application monitoring instructions 113, when executed by processor 120, may determine whether the obtained information meets an end condition associated with extended mode. Responsive to the end condition being met, the application monitoring instructions 113, when executed by processor 120, may monitor the application in regular mode. For example, each condition of the set of conditions based on which the application is monitored in extended mode may be associated with an end condition which, when met, indicates that the application should no longer be monitored in extended mode. In another example, the application monitoring instructions 113, when executed by processor 120, may receive the end condition as an indication from the server computing device 200. In another example, the end condition may be received with the current mode information and/or indication of monitoring mode from the server computing device 200. The end condition may be determined in other ways as well and is not limited to the examples described herein.
In some examples, the application monitoring instructions 113, when executed by processor 120, may end monitoring of the application flow responsive to receiving an indication from the server computing device 200 to end monitoring of the application.
Referring now to the drawings,
Processor 220 may be one or more central processing units (CPUs), microprocessors, and/or other hardware devices suitable for retrieval and execution of instructions stored in machine-readable storage medium 210. Processor 220 may fetch, decode, and execute program instructions 211, 212, and/or other instructions to enable monitoring of applications running on the server computing device 200, as described below. As an alternative or in addition to retrieving and executing instructions, processor 220 may include one or more electronic circuits comprising a number of electronic components for performing the functionality of one or more of instructions 211, 212, and/or other instructions.
In one example, the instructions 211, 212, and/or other instructions can be part of an installation package that can be executed by processor 220 to implement the functionality described herein. In this case, memory 210 may be a portable medium such as a CD, DVD, or flash drive or a memory maintained by another server computing device from which the installation package can be downloaded and installed. In another example, the program instructions may be part of an application or applications already installed on server computing device 200.
Machine-readable storage medium 210 may be any hardware storage device for maintaining data accessible to server computing device 200. For example, machine-readable storage medium 210 may include one or more hard disk drives, solid state drives, tape drives, and/or any other storage devices. The storage devices may be located in server computing device 200 and/or in another device in communication with server 200. As detailed below, storage medium 210 may maintain and/or store the data and information described herein.
For example, machine-readable storage medium 210 may be any electronic, magnetic, optical, or other physical storage device that stores executable instructions. Thus, machine-readable storage medium 210 may be, for example, Random Access Memory (RAM), an Electrically-Erasable Programmable Read-Only Memory (EEPROM), a storage drive, an optical disc, and the like. As described in detail below, machine-readable storage medium 210 may be encoded with executable instructions for determining user experience of an application.
Machine-readable storage medium 210 may store mode information 211 as well as first mode determination instructions 212, first mode determination instructions 213, and/or other instructions that may be used to carry out the functionality of the invention.
First mode determination instructions 212, when executed by processor 210, may determine a first monitoring mode by which application flow for a first application on a first client computing device 100 is monitored, wherein the first monitoring mode is one of a regular mode, an extended mode, and/or other monitoring mode. The first mode determination instructions 212, when executed by processor 210, may determine a first monitoring mode for a first application running on a first client computing device 100 responsive to receiving a request from the first client computing device 100 for a monitoring mode.
In some examples, the request may comprise monitoring information related to application flow for the first application running on the first client computing device 100. In some examples, the request may not comprise additional information.
The first mode determination instructions 212, when executed by processor 210, may determine a monitoring mode for the first application in various manners. The first mode determination instructions 212, when executed by processor 210, may determine the monitoring mode for the first application based on mode information 211 stored at the server computing device 200, based on received customer preferences, based on random selection, and/or based on other manners of determination.
For example, the first mode determination instructions 212, when executed by processor 210, may determine that the first monitoring mode comprises the extended mode based on random selection of the first client computing device 100 to be monitored in extended mode. In another example, the first mode determination instructions 212, when executed by processor 210, may determine that the first monitoring mode comprises the regular mode based on random selection of the first client computing device 100 to be monitored in regular mode.
In another example, the first mode determination instructions 212, when executed by processor 210, may determine that the first monitoring mode comprises the extended mode based on at least a portion of the received monitoring information meeting a predetermined condition of a set of conditions associated with the extended mode. An individual condition may comprise, for example, a set of information that may match a portion of the received monitoring information, characteristics of the first application running on the first client computing device 100, characteristics of the first client computing device 100, and/or other information related to the first application. In some examples, each individual condition may be associated with a predetermined set of information to be monitored in extended mode responsive to the condition being met.
The first mode determination instructions 212, when executed by processor 210, may send to the requesting first client computing device 100 an indication to monitor the application in extended mode, along with the individual condition that was met, the set of predetermined information associated with the condition, and/or other information related to the condition that was met responsive to an individual condition being met.
In another example, the first mode determination instructions 212, when executed by processor 210, may determine that the first monitoring mode comprises the regular mode based on the received monitoring information not meeting any of the predetermined conditions of the set of conditions associated with the extended mode.
In yet another example, the first mode determination instructions 212, when executed by processor 210, may determine that the first monitoring mode comprises the extended mode based on a portion of the received monitoring information meeting a predetermined set of criteria received from a customer. A customer may comprise, for example, an application owner, an application developer, an entity authorized by the application owner, and/or other third party with an interest in the application.
An individual set of customer criteria may comprise, for example, a set of information that may match a portion of the received monitoring information, characteristics of the first application running on the first client computing device 100, characteristics of the first client computing device 100, a ratio of client computing devices to be monitored in extended mode as compared to regular mode, a predetermined number of client computing devices to be monitored in extended mode, a total amount of bandwidth to be used for application flow monitoring across the applications being run on the client computing devices, any combination thereof, and/or other criteria. In some examples, each individual set of criteria may be associated with a predetermined set of information to be monitored in extended mode responsive to the condition being met.
The first mode determination instructions 212, when executed by processor 210, may send to the requesting first client computing device 100 an indication to monitor in extended mode, along with the individual set of criteria that was met, the set of predetermined information associated with the set of criteria, and/or other information related to the set of criteria responsive to an individual set of criteria being met.
In another example, the first mode determination instructions 212, when executed by processor 210, may determine that the first monitoring mode comprises the regular mode based on the received monitoring information not meeting any predetermined set of criteria received from a customer.
In some examples, the first mode determination instructions 212, when executed by processor 210, may determine a monitoring mode based on bandwidth used by the client computing device 100. The amount of bandwidth used by the client computing device 100 may be added to an amount of bandwidth used by other client computing devices that run the first application and from which application flow is monitored to determine a total amount of bandwidth. In some examples, only the amount of bandwidth used to monitor applications in extended mode may be used to calculate the total amount of bandwidth used by other client computing devices.
Bandwidth may exist to monitor the application running on the client computing device 100 responsive to the total amount of bandwidth being less than a predetermined threshold amount. The predetermined threshold amount may be preset by the server computing device 200, by a system administrator, received from a customer, and/or otherwise determined. Other ways of determining whether bandwidth exists may also be used and are not limited to the examples described herein.
In these examples, the first mode determination instructions 212, when executed by processor 210, may compare the received monitoring information with the set of conditions, customer criteria, and/or other information based on which the application would be monitored in extended mode. Responsive to a determining that the application should be monitored in extended mode, the first mode determination instructions 212, when executed by processor 210, may determine whether bandwidth exists for the client computing device 100 to enter extended mode based on the amount of bandwidth that the client computing device would use to monitor in extended mode. For example, the first mode determination instructions 212, when executed by processor 210, may determine the specifications (e.g., characteristics) associated with the client computing device 100, may determine the information to be obtained during extended mode based on the information met, and may calculate an amount of bandwidth that may be used by the client computing device 100 to monitor in extended mode.
In these examples, responsive to the total amount of bandwidth used by all of the client computing devices monitoring the application and the calculated amount of bandwidth being less than the predetermined threshold, the first mode determination instructions 212, when executed by processor 210, may determine that bandwidth exists. Otherwise, the first mode determination instructions 212, when executed by processor 210, may determine that bandwidth does not exist.
In these examples, responsive to bandwidth existing, the first mode determination instructions 212, when executed by processor 210, may send an indication to the client computing device 100 to monitor the application in the determined extended mode.
In these examples, responsive to determining that bandwidth does not exist, the first mode determination instructions 212, when executed by processor 210, may determine whether the server can send an indication to another client computing device to end monitoring in extended mode. Responsive to determining that the server can send an indication to another client computing device to end monitoring in extended mode, the first mode determination instructions 212, when executed by processor 210, may send the end indication to the another client computing device. In some examples, the first mode determination instructions 212, when executed by processor 210, may make this determination based on an amount of time that the another client computing device has been monitoring the application in extended mode, a number of client computing devices monitoring the application in a same type of extended mode, and/or based on other factors related to monitoring the application.
In these examples, responsive to sending an indication to another client computing device to end extended mode monitoring, the first mode determination instructions 212, when executed by processor 210, may send an indication to the client computing device 100 to monitor the application in the determined extended mode.
In these examples, responsive to no condition, customer criteria, or other information being met based on which the application would be monitored in extended mode, the first mode determination instructions 212, when executed by processor 210, may determine whether bandwidth exists to monitor the application running on the client computing device 100 in extended mode. Responsive to bandwidth existing, the first mode determination instructions 212, when executed by processor 210, may randomly select a client computing device requesting a mode indication and send an indication to that randomly selected client computing device to monitor the application in extended mode. In some examples, the first mode determination instructions 212, when executed by processor 210, may also send information related to a set of conditions, customer criteria, and/or other information which may or may not have been met by the selected client computing device.
In some examples, the first mode determination instructions 212, when executed by processor 210, may determine a monitoring mode based on whether a predetermined number of client computing devices are monitoring applications in extended mode. For example, responsive to determining that less than the predetermined number of client computing devices are being monitored in extended mode, the first mode determination instructions 212, when executed by processor 210, may randomly select a client computing device (e.g., client computing device 100) and may send the client computing device an indication to monitor the application running thereon in extended mode.
In some examples, the first mode determination instructions 212, when executed by processor 210, may determine a monitoring mode based solely on random selection. For example, for each client computing device that requests a monitoring mode, the first mode determination instructions 212, when executed by processor 210, may randomly determine whether to send an indication to the requesting client computing device to monitor the application running thereon in extended mode or regular mode.
Second mode determination instructions 122, when executed by processor 210, may determine a second monitoring mode by which application flow for the first application on a second client computing device is monitored, wherein the second monitoring mode is one of the regular mode or the extended mode. The second mode determination instructions 122, when executed by processor 210, may determine the second monitoring mode in a manner the same as or similar to the determination of the first monitoring mode by the first mode determination instructions 121.

For regular mode, the mode nformation may comprise a set of values associated with a respective set of parameters. The predetermined set of information for regular mode may comprise other information as well, and is not limited to the examples described herein.
For extended mode, the mode information 111 may comprise a default predetermined set of information. In some examples, the mode information 111 may also comprise a plurality of predetermined sets of information related to the set of conditions, customer criteria, and/or other information based on which the application may be monitored in extended mode. For example, the mode information 111 may comprise a predetermined set of information for each condition of a set of conditions based on which an application may be monitored in extended mode. In another example, the mode information 111 may comprise a predetermined set of information for each set of criteria supplied by a customer. In another example, the mode information 111 may comprise the combined predetermined sets of information of the previous examples, and/or other information. The predetermined set of information for extended mode is not limited to the examples described herein.

Mode management engine 450 may manage the modes by which application flow is monitored. The mode management engine 450 may maintain mode information for the modes by which application flow is monitored. For example, the mode management engine 450 may maintain a set of conditions whereby an application is monitored in extended mode responsive to an individual condition being met. In some examples, the mode management engine 450 may determine new conditions based on received application monitoring information from client computing devices. The mode management engine 450 may also update mode information with new conditions for extended mode based on the determined new conditions.
In some examples, the mode management engine 450 may aggregate the stored monitoring information received from the client computing devices running the application and monitoring application flow thereon. The mode management engine 450 may determine new conditions based on the aggregated data, may remove or make inactive existing conditions based on the aggregated data, and/or may otherwise manage information related to the modes by which the application is monitored.
In some examples, and as depicted in
Customer mode management engine 452 may receive a new condition to include in the set of conditions from a customer associated with the application. As discussed above, a customer may be an application developer, application owner, entity delineated by an application owner, and/or other third party with an interest in the application.
Condition management engine 454 may determine a new condition to include in the set of conditions based on the received monitoring information from the client computing devices running the application and monitoring application flow. The condition management engine 454 may compare received monitoring information for an application from the client computing device 100 with stored monitoring information received from the client computing devices running the application.
Responsive to a difference between a set of parameters of the received monitoring information and the saved information exceeding a predetermined threshold, the condition management engine 454 may determine whether a condition exists to monitor that set of parameters.
Responsive to determining that no condition exists, the condition management engine 454 may create a new condition. The condition management engine 454 may determine an environment in which the received monitoring information was received. The condition management engine 454 may then determine whether to create a new condition.
