Abstract

An apparatus to diagnose a live service includes a processor circuit; and a request handler component executing on the processor circuit to service a process request that generates process data. The request handler component may comprise a process object to receive a query comprising: a property to fetch and a condition. The process object may further comprise a condition evaluator to evaluate the condition against an executing process request; and a data requestor to fetch the property from the process data when the condition is true, and to write the property to a log file.

Claims

1. An apparatus, comprising:

a processor circuit; and

a request handler component for execution on the processor circuit to service a process request, wherein process data is generated, the request handler component comprising;

a process object to receive a query comprising a property name and a condition, the process object further comprising;

a condition evaluator to evaluate the condition against the process request; and

a data requestor to fetch a property associated with the property name from the process data when the condition is true, and write the property to a log file.

2. The apparatus of claim 1, the process to register with a remote procedure call (RPC) server component when the process starts up, the registering including a set of process data that the process is exposing.

3. The apparatus of claim 1, the process object comprising a query parser to parse the query into one or more conditionals and store the one or more conditionals in a conditional cache for evaluation.

4. The apparatus of claim 1, the process object including a pointer to the process data, wherein the data requestor uses the pointer to the process data to fetch the property.

5. The apparatus of claim 1, wherein the process data comprises at least one of diagnostic data and metadata.

6. The apparatus of claim 1, wherein the process prompts the process object to evaluate the condition.

7. The apparatus of claim 1, the query further comprising metadata to modify the condition.

8. The apparatus of claim 1, the process object to register the query with a remote procedure call (RPC) server component and provide an identifier for the query.

9. A computer-implemented method, comprising:

receiving a query with a property name and a condition at a process;

evaluating the condition against an executing process request;

fetching a property with the property name when the condition is true; and

returning the fetched property to a client that sent the query.

10. The computer-implemented method of claim 9, comprising:

registering the request handler component with a remote procedure call (RPC) server component when the process starts; and

receiving the process request from the RPC server component.

11. The computer-implemented method of claim 9, comprising:

writing the fetched property to a log file.

12. The computer-implemented method of claim 11, comprising:

receiving a request to view the log file from the client; and

providing to the client at least one of;

the log file and a link to the log file.

13. The computer-implemented method of claim 9, comprising:

registering an identifier for the query at a remote procedure call (RPC) server component; and

returning the identifier to the client that sent the query.

14. The computer-implemented method of claim 9, comprising:

parsing the query into one or more conditionals; and

storing the conditionals in a conditional cache.

15. At least one computer-readable storage memory unit comprising instructions that, when executed, cause a system to:

receive a query comprising a property to fetch and a condition;

evaluate the condition against a process request;

fetch the property from process data when the condition is true; and

return the fetched property to a client that sent the query.

16. The computer-readable storage medium of claim 15, comprising instructions that when executed cause the system to register the query with a remote procedure call (RPC) server component and provide an identifier for the query.

17. The computer-readable storage medium of claim 15, comprising instructions that when executed cause the system to:

parse the query into one or more conditionals; and

store the one or more conditionals in a conditional cache for evaluation against the process request.

18. The computer-readable storage medium of claim 17, comprising instructions that when executed cause the system to write the fetched property to a log file.

19. The computer-readable storage medium of claim 15, comprising instructions that when executed cause the system to evaluate the condition against the process request while the process request is executing or after the process request is executed.

20. The computer-readable storage medium of claim 15, comprising instructions that when executed cause the system to receive a prompt from the process request to evaluate the condition.
