Monitoring domain’s generic gates

Table 73 summarizes the monitoring domain’s generic gates. It shows the level-1 trace point IDs of the modules providing the functions for the gates, the functions provided by the gates, and the generic formats for calls to the gates.

Functions and parameters

In initialization processing, the monitoring domain sets the initial monitoring options:

For a cold start, the information comes from the system initialization parameters; for any other type of start, the information comes from the global catalog, but is then modified by any relevant system initialization parameters.

In addition:

In quiesce processing, the monitoring domain waits for all transactions that it is monitoring to terminate. Then the final data in the performance class buffer and the transaction resource class buffer, if any, is written to SMF.

The monitoring domain does no termination processing.
