chactl query calibration

Use the chactl query calibration command to view detailed information about the calibration data of a specific target.

Syntax

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

The following Key Performance Indicators are supported for cluster:

  • CPUPERCENT - CPU utilization - Percent

  • IOREAD - Disk read - Mbyte/sec

  • 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
