Analyzing thread history


The HTLOGS view provides access to detailed thread accounting data in any of the trace data sources.

Accessing and analyzing a large number of detail records can be very time consuming, but HTLOGS provides two methods for choosing only the threads you need to analyze. This feature is especially useful when working with a large BMC AMI Ops Monitor for Db2 Data Collector active trace data set.

You can use either of the following methods, or a combination of them, based on what you need to analyze:

  • A thread history drill down of interval summary data–from 15 to 5 to 1 minute intervals of data–can help you identify problem threads in a particular time period, or detect a time period with problems.
  • A thread query with extensive filtering options can help you find specific conditions or workload qualifiers in threads that might be distributed throughout all of the records traced.
