C.9 chactl query calibration
Use the chactl query calibration command to view detailed information about the calibration data of a specific target.
Syntax
Note:
Applicable only if GIMR is configured. GIMR is optionally supported in Oracle Database 19c. However, it's desupported in Oracle Database 23ai.chactl query calibration {-cluster|-db db_unique_name} [-timeranges 'start=time_stamp,end=time_stamp,...'] [-kpiset 'name=kpi_name min=val max=val,...' ] [-interval val][-help]Specify the interval in hours.
Specify date and time in the YYYY-MM-DD HH24:MI:SS format.
Note:
If you do not specify a time interval, then the chactl query calibration command displays all the calibration data collected for a specific target.
The following Key Performance Indicators are supported for database:
-
CPUPERCENT- CPU utilization - Percent -
IOREAD- Disk read - Mbyte/sec -
DBTIMEPERCALL- Database time per user call - usec/call -
IOWRITE- Disk write - Mbyte/sec -
IOTHROUGHPUT- Disk throughput - IO/sec

Examples
To view detailed information about the calibration data of the specified target:
$ chactl query calibration -db oltpacdb -timeranges
'start=2016-07-26 01:00:00,end=2016-07-26 02:00:00,start=2016-07-26 03:00:00,end=2016-07-26 04:00:00'
-kpiset 'name=CPUPERCENT min=20 max=40, name=IOTHROUGHPUT min=500 max=9000' -interval 2
