How do you divide a count of events in timechart?

[mark_groenveld]

We would like to count the number of error events in 15 minute intervals and show that number as the number of errors per minute for the previous 15 minutes. How would I do that using the timechart command?

Sample search: index=main loglevel=error earliest=-15m | timechart span=15m

What would the rest be?

See if this gives you what you're looking for

index=_internal error  | timechart span=15m count | eval min=count/15 

OR

 index=_internal error  earliest=-15m@m | timechart span=1m count
