Abstract

Techniques for gathering information during runtime of a monitored system such that the information is available for facilitating diagnostics for the monitored system. In one embodiment, upon detection of a condition (such as an error condition) in the monitored system, a portion of the gathered information provides contextual information that facilitates gathering of diagnostic data that is relevant for the detected condition. This facilitates capturing of diagnostic data that is relevant for diagnosing the detected condition. The information gathered and stored during runtime may include information related to local variables, information related to tagged information (e.g., tagged functions/processes) executing in the monitored system, information related to potential impacts to the monitored system due to failures, metadata information, and other information.

Claims

1. A method for gathering and storing information for use in diagnostic data dumping in a monitored system, comprising:

gathering information related to the monitored system during runtime of the monitored system;

storing the gathered information during runtime of the monitored system;

retrieving a portion of the stored information in response to a condition detected in the monitored system; and

wherein the retrieved information is used for determining one or more diagnostic actions to be performed in response to the detected condition.

2. The method of claim 1 wherein gathering the information related to the monitored system during runtime comprises gathering information related to one or more local variables used in a function that is executed by the monitored system.

3. The method of claim 2 wherein gathering the information related to one or more local variables comprises gathering one or more attributes associated with the local variable.

4. The method of claim 3 wherein gathering one or more attributes associated with the local variable comprises gathering an identifier associated with the local variable, a type associated with the local variable, a size of the local variable, a callback function associated with the local variable, or combinations thereof.

5. The method of claim 1 wherein gathering the information related to the monitored system comprises gathering information related to a function or process that is tagged as relevant for diagnosis.

6. The method of claim 1 wherein gathering the information related to the monitored system comprises gathering information related to a probable impact related to the condition detected in the monitored system.

7. The method of claim 1 wherein gathering the information related to the monitored system comprises gathering metadata information, the metadata information comprising one or more correlation keys.

8. The method of claim 1 wherein storing the gathered information during runtime comprising pushing the gathered information into a stack.

9. The method of claim 1 further comprising dumping the retrieved information to a disk.

10. The method of claim 1 wherein the retrieved information is used for determining a diagnostic action to be performed that gathers diagnostic data relevant for the detected condition.

11. The method of claim 1 further comprising receiving information identifying information related to the monitored system to be gathered and stored during runtime of the monitored system.

12. The method of claim 11 wherein the information identifying information to be gathered and stored during runtime is received during runtime of the monitored system.

13. A computer readable storage medium storing a plurality of instructions for controlling a processor to gather and store information for use in diagnostic data dumping in a monitored system, the plurality of instructions comprising:

instructions that cause the processor to gather information related to the monitored system during runtime of the monitored system;

instructions that cause the processor to store the gathered information during runtime of the monitored system;

instructions that cause the processor to retrieve a portion of the stored information in response to a condition detected in the monitored system; and

instructions that cause the processor to use the retrieved information for determining one or more diagnostic actions to be performed in response to the detected condition.

14. The computer readable storage medium of claim 13 wherein the instructions that cause the processor to gather information related to the monitored system during runtime of the monitored system comprise instructions that cause the processor to gather information related to one or more local variables used in a function that is executed by the monitored system.

15. The computer readable storage medium of claim 14 wherein the instructions that cause the processor to gather the information related to one or more local variables comprise instructions that cause the processor to gather one or more attributes associated with the local variable.

16. The computer readable storage medium of claim 15 wherein the instructions that cause the processor to gather one or more attributes associated with the local variable comprise instructions that cause the processor to gather an identifier associated with the local variable, a type associated with the local variable, a size of the local variable, a callback function associated with the local variable, or combinations thereof.

17. The computer readable storage medium of claim 13 wherein the instructions that cause the processor to gather information related to the monitored system during runtime of the monitored system comprise instructions that cause the processor to gather information related to a function or process that is tagged as relevant for diagnosis.

18. The computer readable storage medium of claim 13 wherein the instructions that cause the processor to gather information related to the monitored system during runtime of the monitored system comprise instructions that cause the processor to gather information related to a probable impact related to the condition detected in the monitored system.

19. The computer readable storage medium of claim 13 wherein the instructions that cause the processor to gather information related to the monitored system during runtime of the monitored system comprise instructions that cause the processor to gather metadata information, the metadata information including one or more correlation keys.

20. A system for gathering and storing information for use in diagnostic data dumping in a monitored system, the system comprising:

a memory; and

a processor coupled to the memory;

wherein the processor is configured to;

gather information related to the monitored system during runtime of the monitored system;

store the gathered information during runtime of the monitored system;

retrieve a portion of the stored information in response to a condition detected in the monitored system; and

wherein the retrieved information is used for determining one or more diagnostic actions to be performed in response to the detected condition.
