Abstract

Techniques for proactively and reactively running diagnostic functions. These diagnostic functions help to improve diagnostics of conditions detected in a monitored system and to limit/quarantine the damages caused by the detected conditions. In one embodiment, a health monitor infrastructure is provided that is configured to perform one or more health checks in a monitored system for diagnosing and/or gathering information related to the system. The one or more health checks may be invoked pro-actively on a scheduled basis, reactively in response to a condition detected in the system, or may even be invoked manually by a user such as a system administrator.

Claims

1. A method for monitoring a system, comprising:

executing a health check to determine information related to the system, wherein the health check is invoked based upon a predefined schedule or in response to one or more conditions detected in the system; and

outputting the information related to the system determined from executing the health check.

2. The method of claim 1 wherein, the health check is invoked based upon a predefined schedule comprises scheduling the health check in a designated maintenance window.

3. The method of claim 1 wherein the one or more conditions detected in the system identify an error in the system and the health check is invoked in response to the error.

4. The method of claim 1 wherein executing the health check comprises:

determining a set of one or more rules configured for the system, each rule specifying one or more conditions and an action to be performed when the one or more conditions are satisfied; and

determining that the one or more conditions associated with a first rule from the set of rules are satisfied by the one or more conditions detected in the system, wherein the action specified by the first rule is the execution of the health check.

5. The method of claim 1 wherein executing the health check comprises:

executing the health check in a first time window;

stopping the execution of the health check at the end of the first time window; and

continuing the execution of the health check at a point of time that is subsequent to and non-contiguous from the end of the first time window using information stored from the execution of the health check in the first time window.

6. The method of claim 1 further comprising detecting one or more errors based upon the information determined from executing the health check.

7. The method of claim 6 further comprising aggregating the one or more errors based upon information associated with the one or more errors.

8. The method of claim 6 further comprising periodically validating the one or more errors.

9. The method of claim 6 further comprising providing a recommendation for at least one error from the one or more errors detected from executing the health check, the recommendation identifying one or more actions to be performed for repairing or mitigating an impact the at least one error.

10. The method of claim 1 further comprising:

determining a set of one or more rules configured for the system, each rule specifying one or more conditions and an action to be performed when the one or more conditions are satisfied; and

determining a first rule from the set of rules whose associated one or more conditions are satisfied based upon the information determined from executing the health check; and

executing an action specified by the first rule, wherein executing the action comprises executing a second health check.

11. The method of claim 1 further comprising generating a report based upon the information determined from executing the health check.

12. A computer-readable storage medium storing a plurality of instructions for controlling a processor to monitor a system, the plurality of instructions comprising:

instructions that cause the processor to execute a health check to determine information related to the system, wherein the health check is invoked based upon a predefined schedule or in response to the one or more conditions detected in the system, and

instructions that cause the processor to output the information related to the system determined from executing the health check.

13. The computer-readable storage medium of claim 12 wherein the instructions that cause the processor to execute the health check comprise:

instructions that cause the processor to determine a set of one or more rules configured for the system, each rule specifying one or more conditions and an action to be performed when the one or more conditions are satisfied; and

instructions that cause the processor to determine that the one or more conditions associated with a first rule from the set of rules are satisfied by the one or more conditions detected in the system, wherein the action specified by the first rule is the execution of the health check.

14. The computer-readable storage medium of claim 12 wherein the instructions that cause the processor to execute the health check comprise:

instructions that cause the processor to execute the health check in a first time window;

instructions that cause the processor to stop the execution of the health check at the end of the first time window; and

instructions that cause the processor to continue the execution of the health check at a point of time that is subsequent to and non-contiguous from the end of the first time window using information stored from the execution of the health check in the first time window.

15. The computer-readable storage medium of claim 12 wherein the plurality of instructions further comprises instructions that cause the processor to detect one or more errors based upon the information determined from executing the health check.

16. The computer-readable storage medium of claim 15 wherein the plurality of instructions further comprises instructions that cause the processor to aggregate the one or more errors based upon information associated with the one or more errors.

17. The computer-readable storage medium of claim 15 wherein the plurality of instructions further comprises instructions that cause the processor to periodically validate the one or more errors.

18. The computer-readable storage medium of claim 15 wherein the plurality of instructions further comprises instructions that cause the processor to provide a recommendation for at least one error from the one or more errors detected from executing the health check, the recommendation identifying one or more actions to be performed for repairing or mitigating an impact the at least one error.

19. The computer-readable storage medium of claim 12 wherein the plurality of instructions further comprises instructions that cause the processor to generate a report based upon the information determined from executing the health check.

20. A system for monitoring a system, the system comprising:

a memory; and

a processor coupled to the memory;

wherein the processor is configured to;

execute a health check to determine information related to the system, wherein the health check is invoked based upon a predefined schedule or in response to one or more conditions detected in the system; and

output the information related to the system determined from executing the health check.
