Launches the LDC_LAG_MONITOR background job if it is halted or never started before. The LDC_LAG_MONITOR background job works only in the Kafka mode and when the FRMCARINA034 (ENABLE_LIVE_DATA_CACHING) setting is set to true.
You must manually create the LDC_LAG_MONITOR_JOB_GROUP if it is not already created and then launch the LDC_LAG_MONITOR background job.
When you click the Launch LDC Kafka Lag Monitor Job sub-menu item, N4 displays an appropriate error message if you launch the LDC_LAG_Monitor background job for the following scenarios:
when the N4 is in the AMQ mode.
when the FRMCARINA034 (ENABLE_LIVE_DATA_CACHING) setting is disabled.
when the LDC_LAG_MONITOR_JOB_GROUP is not defined.
