Abstract

A system manager tests, administers and monitors, and/or diagnoses problems with a distributed system having a plurality of computing machines. Each machine includes an event monitoring agent and the system manager comprises a data collection module (DCM), a data management module (DMM), a data storing module (DSM), and a user interface module (UIM). The DCM receives a request from the DMM describing performance data to be collected from each agent, and based on the request the DCM then collects such performance data from each agent and sends same to the DMM. The DMM stores the performance data at the DSM along with metadata corresponding to the request for current and future usage, including monitoring, analyzing and evaluation. The UIM receives requests from a user and forwards same to the DMM, and formats data from the DSM and represents the formatted data to the user.

Claims

1. A system manager for testing, administering and monitoring, and/or diagnosing problems with a distributed system having a plurality of computing machines, each machine including an event monitoring agent for monitoring for one or more pre-defined events occurring on the machine and/or for collecting usage statistics with respect to the machine, the system manager comprising a data collection module (DCM), a data management module (DMM), a data storing module (DSM), and a user interface module (UIM),

the DCM for receiving a request from the DMM describing performance data to be collected from each of one or more of the machines of the system by way of the agent thereof, and based on the request for collecting such performance data from each agent and sending same to the DMM,

the DMM for receiving the sent performance data from the DCM and storing the received performance data at the DSM along with metadata corresponding to the request for current and future usage, including monitoring, analyzing and evaluation,

the UIM for receiving requests from a user and forwarding each received request to the DMM, and for formatting data from the DSM and representing the formatted data to the user,

the DSM for storing performance data and corresponding metadata, the performance data comprising data as received from each agent in the system including raw values of a specific performance counter, the metadata comprising a description relating to circumstances of collecting the performance data, including data description information, data environment information, and a rule requiring performance of an action in response to a detection of a condition from performance data,

the DMM for enforcing each rule by reviewing the performance data as received to determine if the condition thereof is met, and if so taking the corresponding action.

2. The system manager of claim 1 wherein the DCM receives a request from the DMM describing performance data to be collected from each of multiple ones of the machines of the system in a coordinated and collated fashion, whereby performance data from a first one of the machines may be compared against performance data from a second one of the machines.

3. The system manager of claim 1 wherein the DCM collects performance data from each agent by contacting each relevant agent based on the request, directing the contacted agent to send the requested performance data to the DCM, and collecting the requested performance data from the directed agent.

4. The system manager of claim 1 wherein the DMM transforms the received performance data as necessary prior to storing same at the DSM.

5. The system manager of claim 1 wherein the DSM is implemented as a relational database that can be queried.

6. The system manager of claim 1 wherein the condition is an instantaneous condition and the DMM determines whether the instantaneous condition is met based on reviewing the performance data as received.

7. The system manager of claim 1 wherein the condition is a trend condition and the DMM determines whether the trend condition is met based on reviewing the performance data as received and also the performance data as stored at the DSM.

8. The system manager of claim 1 wherein the DMM reviews the performance data in an ongoing manner to determine if the condition is met such that the condition is detected and the action is taken in real- or near-real-time.

9. The system manager of claim 1 wherein the UIM accesses an object model of the DMM to assist the user in setting up the same and an object model of the DSM to assist the user in retrieving and analyzing data from the DSM.

10. The system manager of claim 9 wherein the UIM accesses representation logic for representing the DMM and DSM to the user based on the object models thereof, and for representing the retrieved and analyzed data to the user.

11. The system manager of claim 9 wherein the UIM accesses a library available to the user, the library having pre-defined requests for the DMM, queries for data from the DSM, and data representation formats for the UIM.

12. The system manager of claim 9 wherein the UIM accesses a tool available to the user to assist in creating requests for the DMM, queries for data from the DSM, and data representation formats for the UIM.

13. A method for testing, administering and monitoring, and/or diagnosing problems with a distributed system having a plurality of computing machines, each machine including an event monitoring agent for monitoring for one or more pre-defined events occurring on the machine and/or for collecting usage statistics with respect to the machine, the method employing a system manager including a data collection module (DCM), a data management module (DMM), and a data storing module (DSM), the method comprising:

receiving, by the DCM, a request from the DMM describing performance data to be collected from each of one or more of the machines of the system by way of the agent thereof;

collecting, by the DCM and based on the request, such performance data from each agent;

sending, by the DCM, the collected performance data to the DMM;

receiving, by the DMM, the sent performance data from the DCM; and

storing, by the DMM, the received performance data at the DSM along with metadata corresponding to the request for current and future usage, including monitoring, analyzing and evaluation,

the DSM storing performance data and corresponding metadata, the performance data comprising data as received from each agent in the system including raw values of a specific performance counter, the metadata comprising a description relating to circumstances of collecting the performance data, including data description information, data environment information, and a rule requiring performance of an action in response to a detection of a condition from performance data,

the DMM enforcing each rule by reviewing the performance data as received to determine if the condition thereof is met, and if so taking the corresponding action.

14. The method of claim 13 comprising the DCM receiving a request from the DMM describing performance data to be collected from each of multiple ones of the machines of the system in a coordinated and collated fashion, whereby performance data from a first one of the machines may be compared against performance data from a second one of the machines.

15. The method of claim 13 comprising the DCM collecting performance data from each agent by contacting each relevant agent based on the request, directing the contacted agent to send the requested performance data to the DCM, and collecting the requested performance data from the directed agent.

16. The method of claim 13 further comprising the DMM transforming the received performance data as necessary prior to storing same at the DSM.

17. The method of claim 13 comprising the DMM storing the received performance data and corresponding metadata in a relational database at the DSM.

18. The method of claim 13 wherein the condition is an instantaneous condition and comprising the DMM determining whether the instantaneous condition is met based on reviewing the performance data as received.

19. The method of claim 13 wherein the condition is a trend condition and comprising the DMM determining whether the trend condition is met based on reviewing the performance data as received and also the performance data as stored at the DSM.

20. The method of claim 13 comprising the DMM reviewing the performance data in an ongoing manner to determine if the condition is met such that the condition is detected and the action is taken in real- or near-real-time.

21. The method of claim 13 employing a system manager further including a user interface module (UIM) having access to an object model of the DMM and an object model of the DSM, the method further comprising employing the DMM object model by the UIM to set up the DMM and employing the DSM object model by the UIM to retrieve and analyze data from the DSM.
