The trace alert system notifies you when your specified threshold for network, host, or user response time has been exceeded. When it is determined that the response time is higher for a transaction than the threshold specified on the TRACENET, TRACEHST, or TRACEUSR parameter, an exception trace entry is created. It displays the statistics online at your request.
You can specify the TRACENET, TRACEHST, and TRACEUSR parameters globally or at an individual application level on an APPL statement.
You can create resource lists through the Default Resource List Initialization Menu or the RLIST explicit command.
Note: The resources for which data appears on Trace Alert System Display depend on whether you create a FORAPPL or LU resource list. Resource lists contain specific resource names to include in or exclude from graphic and trace alert displays. Resource lists can also contain the names of one or more files that contain specific resource names. If there are no FORAPPL or LU resource lists, data on all known APPLs and LUs appears in the display.
The Trace Alert System Display shows exception and transaction-all transaction trace alerts. The display lists trace alerts for various terminals, providing host and network response times.

The top line displays the current date and time. This screen is refreshed every 30 seconds.
You have 5–10 minutes of data on your screen at a time. If you have more, set the TRACENET, TRACEHST, and TRACEUSR thresholds higher and check for possible network problems. Statistics are displayed only when thresholds are exceeded.
Note: Periodically, old entries are purged (keeping only the number of entries determined by MAXTRACE x 2) to make space for new entries. This feature explains why old entries are erased from the trace alert display.
