Viewing a historical statistics trace

The Historical Statistics Trace panel displays hourly trace information. Monitoring transaction throughput can help you establish a transaction threshold for the WorkLoad Governor. For more information about the WorkLoad Governor, see Using-the-Workload-Governor.

The first panel displays datastores and exits for which trace data is available. The ALL line references totals that include all datastores and exits. The DataStor - none line includes messages that did not get sent to a DataStore, possibly because of an error. All messages that are sent to that IPRCMDS0 exit are included in this category because the messages are Energizer commands that are processed in IMS Connect.

The Avg Resp. Time column shows the average response time for CM0 and CM1 messages that are processed by a datastore. Response time starts when the first message is received by the READ exit and ends when the first response from the datastore is received by the XMIT exit.

Note

The following response times are not included in the average:

  • Response time for confirmation (ACK/NAK) message
  • Response time that is greater than an hour
  • Response time for SENDONLY, RESUME TPIPE, and SYNCH CALLOUT RESPONSE messages

To filter a display type

Enter the filtering criteria on the line below the column headings.

For example, to filter on exits, type a unique portion of the word exit, such as EX, under the Type heading and press Enter. Only exit information is displayed.

Note

Filtering criteria remain in effect until you delete the criteria.

To display intervals for one of the types

Type S next to the messages that you want displayed in the report, and press Enter. The following figure shows a sample Statistics Trace Interval panel:

To display a report

  1. Position the cursor in the action field Statistics Trace Interval panel next to the Timestamp heading.

  2. Type S next to the timestamps that you want displayed in the report, and press Enter.You can scroll and select multiple rows to include in a single report. The following figure shows a sample Query Report for exit HWSSMPL:
