Abstract

A multi-mainframe system problem determination method includes receiving, in a first computing system, a data collection trigger, coordinating, in the first computing system, synchronized diagnostic data collection with a second computing system, and delivering the diagnostic data to a storage medium.

Claims

1. A multi-mainframe system problem determination method, comprising:

recording, in a first computing system, diagnostic data;

receiving, in the first computing system, a data collection trigger;

coordinating, in the first computing system, synchronized diagnostic data collection with a second computing system; and

delivering the diagnostic data to a storage medium.

2. The method as claimed in claim 1 further comprising establishing a trace data channel to record the diagnostic data.

3. The method as claimed in claim 2 further comprising establishing a session identifier.

4. The method as claimed in claim 3 further comprising in response to the trigger, retrieving the trace data associated with the session identifier.

5. The method as claimed in claim 3 further comprising filtering the diagnostic data via the session identifier.

6. The method as claimed in claim 1 wherein the diagnostic data is at least one of trace records, log records and core dumps

7. The method as claimed in claim 1 further comprising collecting clock offset information for combining with trace data.

8. The method as claimed in claim 7 further comprising viewing a sequence of events across multiple components of the multi-mainframe system via the clock offset information to localize problems.

9. A computer program product including a non-transitory computer readable medium storing instructions for causing a computer to implement a multi-mainframe system problem determination method, the method comprising:

recording, in a first computing system, diagnostic data;

receiving, in the first computing system, a data collection trigger;

coordinating, in the first computing system, synchronized diagnostic data collection with a second computing system; and

delivering the diagnostic data to a storage medium.

10. The computer program product as claimed in claim 9 further comprising establishing a trace data channel to collect the diagnostic data.

11. The computer program product as claimed in claim 10 further comprising establishing a session identifier.

12. The computer program product as claimed in claim 11 further comprising in response to the trigger, retrieving the trace data associated with the session identifier.

13. The computer program product as claimed in claim 11 further comprising filtering the diagnostic data via the session identifier.

14. The computer program product as claimed in claim 9 wherein the diagnostic data is at least one of trace records, log records and core dumps

15. The computer program product as claimed in claim 9 further comprising collecting clock offset information for combining with trace data.

16. The computer program product as claimed in claim 15 further comprising viewing a sequence of events across multiple components of the multi-mainframe system via the clock offset information to localize problems.
