Information written to tables for an activities event monitor
Information written by an activities event monitor when the WRITE TO TABLE option is specified.
When you choose WRITE TO TABLE as the ouput type for an activities
event monitor, by default, five tables are produced, each containing
monitor elements from one or more logical data groups:
To restrict the output of the event monitor to specific tables,
specify the names of the logical groups for which you want tables
produced in the CREATE EVENT MONITOR or ALTER EVENT MONITOR statements.
Refer to the reference topics for those statements for details.
Default table name | Logical data groups reported |
---|---|
ACTIVITY_evmon-name | Refer to event_activity in
Event monitor logical data groups and monitor elements |
ACTIVITYSTMT_evmon-name | Refer to event_activitystmt in
Event monitor logical data groups and monitor elements |
ACTIVITYVALS_evmon-name | Refer to event_activityvals in
Event monitor logical data groups and monitor elements |
ACTIVITYMETRICS_evmon-name | Refer to event_activitymetrics in
Event monitor logical data groups and monitor elements |
CONTROL_evmon-name | The CONTROL logical group consists of selected elements from one or more of the event_dbheader, event_start and event_overflow logical data groups. |
Control table
Column Name | Data Type | Description |
---|---|---|
PARTITION_KEY | INTEGER | partition_key - Partitioning key |
EVENT_MONITOR_NAME | VARCHAR(128) | event_monitor_name - Event monitor name |
MESSAGE | VARCHAR(128) | message - Control table message |
MESSAGE_TIME | TIMESTAMP | message_time - Timestamp control table message |
PARTITION_NUMBER | SMALLINT | partition_number - Partition number |
1 Some columns
returned in the ACTIVITY_evmon-name are dependent on the snapshot monitoring
infrastructure. The snapshot statement switch must be enabled (using the DBM parameter DFT_MON_STMT)
to return activity information for them. The metrics returned in these columns do not always align
strictly with activity boundaries. To get more accurate activity metrics, use the corresponding
columns with the same names that are returned in the ACTIVITYMETRICS_evmon-name
table, except for ROWS_READ, now called ROWS_FETCHED, and USER_CPU_TIME and SYSTEM_CPU_TIME, which
are now combined into TOTAL_CPU_TIME.
