CPU Utilization Query

I am using this query to Fetch CPU Utilization details

index=os sourcetype="cpu" | multikv forceheader=1 | eval human_readable_time=strftime(_time, "%Y-%d-%m %H:%M:%S") | eval percentageCPUUtil = 100 - pctIdle | table human_readable_time,host,percentageCPUUtil,pctIdle

But for particular time and for the same host , we are getting multiple rows, Below is the ouput

human_readable_time,host,percentageCPUUtil,pctIdle

If we notice the output, for the same time and same host, we are getting multiple Rows. So which row should be assume is the Percentage CPU Utilization.

But if we add | search CPU=all | in the query, then output we are getting is fine.

Kindly Suggest.

Use Monitoring Console builtin since Splunk 6.5. It is a great feature.

Probably your host has a multicore CPU or several CPUs so in this case you have utilization for each core. Like a solution you can add core number to output and calculate utilization for each core or calculate average value of all rows or use just CPU=all
