How to calculate the total CPU by top result

New Member

Hi, all, I am a newbie in splunk. I have encounter a problem when play around with *NIX app in Splunk. I am going to calculate the total CPU usage in each minutes

   PID  USER              PR    NI    VIRT     RES     SHR   S  pctCPU  pctMEM       cpuTIME  COMMAND
 32206  root              15     0    298m    129m     10m   S    19.3     0.8      15:46.08  splunkd
 14559  root              15     0   13016    1224     708   R     3.9     0.0       0:00.03  top
     1  root              15     0   10348     684     576   S     0.0     0.0       0:04.85  init
     2  root              RT    -5       0       0       0   S     0.0     0.0       0:00.08  migration/0
     3  root              34    19       0       0       0   S     0.0     0.0       0:00.00  ksoftirqd/0
     4  root              RT    -5       0       0       0   S     0.0     0.0       0:00.00  watchdog/0
     5  root              RT    -5       0       0       0   S     0.0     0.0       0:00.13  migration/1
     6  root              34    19       0       0       0   S     0.0     0.0       0:00.00  ksoftirqd/1
     7  root              RT    -5       0       0       0   S     0.0     0.0       0:00.00  watchdog/1

I don't know how to extract the pctCPU value. Any hint?

Thank you.

Regards, Alister

The multikv command helps you to split the tabular formatted events in to separate ones.

You can use a query like this:

sourcetype=ps | multikv | stats sum(pctCPU) as sumPctCPU by _time,host | timechart span=1m avg(sumPctCPU) by host
