The consumer settings in the setup_consumers
table form a hierarchy from higher levels to lower. For detailed information about the effect of enabling
different consumers, see Section 21.2.3.2.1.4, "Pre-Filtering
by Consumer".
The setup_consumers
table has
these columns:
NAME
The consumer name.
ENABLED
Whether the consumer is enabled. This column can be modified. If you disable a consumer, the server does not spend time adding event information to it.
Modifications to the setup_consumers
table affect monitoring immediately.
