Monitoring Capacity Entitlement in Applications Manager
Applications Manager is equipped to monitor processor capacity entitlement issues. To measure the average entitlement value during peak production times with a higher workload, you can use the following command:
- lparstat 1 20 > /tmp/apm_physc.txt && awk '/^..[0-9]/{sum+=$5}END{printf "UtilizationCPUCore: %.2f\n" ,sum/20}' /tmp/apm_physc.txt && awk '/^..[0-9]/{sum+=$6}END{printf "EntitledCPUUtilization: %.2f\n" ,sum/20}' /tmp/apm_physc.txt
This command captures processor statistics every second for 20 seconds and then calculates the average values. The output will look similar to the example below:
- System configuration: type=Shared mode=Uncapped smt=4 Icpu=49 mem=49960MB ent=8.00
- user %sys Xwait %idle physc %entc lbusy vcsw phint %hypv
- 72.3 9.6 0.3 47.8 8.64 108.0 25.2 16113 3996 23.4
- 50.4 18.3 0.5 30.8 11.16 139.5 17.6 25445 2763 39.9
- 40.5 20.7 0.4 38.5 7.81 97.6 12.6 15097 1234 45.7
- 39.0 24.0 0.3 36.7 8.89 411.1 44.7 15619 1394 47.5
- 40.1 23.5 0.3 36.1 10.26 128.3 14.3 16801 1612 44.9
- 39.4 23.7 0.3 36.6 7.81 97.6 13.9 18254 1450 45.7
- 48.6 14.4 0.3 36.6 9.89 123.6 12.9 15123 1581 43.7
From this output, you can extract the average CPU core utilization and the percentage of physical processor consumption. These statistics are relevant only when the partition type is shared.
In the Applications Manager GUI, click on the monitor details under the CPU tab to find the entitlement and utilization details, along with the corresponding graph.
