How to efficiently calculate max events per second (eps) by hour over long timeranges, like 30 days?

I could count against the raw data but it takes a long time. How can I more efficiently count on such stats?

Use tstats and specify the variables:

  • index=main
  • earliest=-30d
  • groupby (_time, sourcetype)
  • span=1s

    | tstats count as COUNT where index=main earliest=-30d by _time,sourcetype span=1s | timechart span=1h max(COUNT) as eps by sourcetype

might suggest a reformat (note in my search i do index=*😞

| tstats count as COUNT where index=* earliest=-30d by _time, sourcetype span=1s
  | timechart span=1h max(COUNT) as eps by sourcetype

FYI -
earliest=-30d and span=1s will produce 1 day = 86400 seconds * 30 days = 2,592,000 

tstats will limit results to 50,000 hence the output of the search will truncate results.
