SMFINTERVAL

The SMFINTERVAL configuration parameter identifies the frequency that the monitor service calls the SMF exit to report active subscription processing metrics.

Description

The SMFINTERVAL configuration is used in conjunction with the SMFEXIT configuration parameter to collect subscription processing metrics for historical analysis. The sample exit (CECSXSMF) produces SMF records.

The SMFINTERVAL configuration parameter identifies how frequently the monitor service calls the exit specified on the monitor service SMFEXIT configuration parameter definition. The monitor service calls the SMFEXIT for each subscription that is replicating changes when an interval expires.

This is a semi-dynamic configuration parameter and new values take effect after the next interval expires. Changing the SMFINTERVAL parameter from a non-zero value to zero, deactivates calling the SMFEXIT to report metrics and subsequently updating the SMFINTERVAL to a non-zero value does not take effect until the server is restarted.

To enable calling the SMFEXIT by the monitoring service, a non-zero value needs to be specified for the SMFINTERVAL configuration parameter, the exit-name (and other required parameters) has to be provided on the SMFEXIT configuration parameter, and the data server must be stopped and restarted.

Upon restart, the monitor service loads the specified exit-name and calls the exit to perform initialization processing. Assuming the load succeeds, and the exit does not report any errors during initialization processing, the monitor service schedules an internal process to run at the interval specified at which time the exit is called for any replicating subscriptions, after which the next schedule interval is determined based on the current SMFINTERVAL value.
