This parameter controls the collection of activity metrics
on the entire database and affects activities submitted by connections
associated with any DB2® workload
definitions.

Note: If you modify the mon_act_metrics parameter
online, only the new activities use the updated value. The existing
activities are not affected.
- Default [range]
- BASE [NONE, BASE, EXTENDED]
- Upgrade Note
- On
databases created before V9.7 and
then upgraded to V9.7 or
higher, the mon_act_metrics parameter is set
to NONE by default.
- If you are upgrading from a DB2 Version 9.8 Fix Pack 4 pureScale
environment or earlier, the value of mon_req_metrics is
set to the value on member 0.
If you set this configuration
parameter to BASE,
activity metrics are collected for all activities executed on the
data server regardless of the DB2 workload
the connection that submitted the activity is associated with.
If
you set this configuration parameter to
EXTENDED,
the same metrics are collected as under the BASE setting. In addition,
the values reported for the following monitor elements are determined
with more granularity:
- total_section_time
- total_section_proc_time
- total_routine_user_code_time
- total_routine_user_code_proc_time
- total_routine_time
For information about how the EXTENDED setting affects these
monitor elements, see the detailed monitor element descriptions.
If
you set this configuration parameter to NONE, activity
metrics are collected only for the subset of activities submitted
by a connection that is associated with a DB2 workload whose COLLECT ACTIVITY METRICS clause
has been set to BASE
The
following monitor interfaces report activity metrics:
- MON_GET_PKG_CACHE_STMT_DETAILS
- MON_GET_ACTIVITY
- MON_GET_ACTIVITY_DETAILS
- MON_GET_PKG_CACHE_STMT
- WLM_GET_WORKLOAD_OCCURRENCE_ACTIVITIES
- Package cache event monitor
- Activity event monitor
If you use these interfaces, consider setting
mon_act_metrics to
a value other than
NONE. Each interface topic contains
a list of the monitor elements that are reported and the details on
whether a monitor element is controlled by the
mon_act_metrics database
configuration parameter.
