Hi,
What is this field pctIdle which automatically gets extracted when we use multikv command?
Is it the avg cpu load?
Is it the percentage of time when CPU was idle?
If i need to calculate the CPU utilisation % of my 2 host, which query and sourcetype should i use from the below 2 queries?
1. index=os sourcetype=top host="host1" OR host="host2"
| timechart span=5m values(pctCPU) by host
2.index=os sourcetype=cpu host="host1" OR host="host2"
| eval Percent_CPU_Load = 100 - pctIdle
| timechart avg(Percent_CPU_Load) by host
Appreciate if someone can help
pctIdle
or Percent Idle Time is percentage of time that the CPU or CPUs were idle and the system did not have an outstanding disk I/O request. Have a look at this to see a comparison of commands used : https://www.cyberciti.biz/tips/how-do-i-find-out-linux-cpu-utilization.html
If you need to calculate CPU utilisation % of hosts, use eval Percent_CPU_Usage = 100 - pctIdle
, see Percent_CPU_Usage
On another note, do you have pctCPU
field? As far as I have seen, the headers for CPU utilization are
CPU pctUser pctNice pctSystem pctIowait pctIdle
Which are
CPU : CPU number
%user: Percentage of CPU utilization that occurred while executing at the user level (application).
%nice: Percentage of CPU utilization that occurred while executing at the user level with nice priority.
%system: Percentage of CPU utilization that occurred while executing at the system level (kernel).
%iowait: Percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request.
%idle: Percentage of time that the CPU or CPUs were idle and the system did not have an outstanding disk I/O request.

Brilliant Thank you
