How to edit my Apdex calculation search to prevent warning "'stats command: limit for values of field 'utt' reached."?

New Member


I'm creating an Apdex SLA report on "user response time" performance in my application. I am aware about the "ApDex Add-on", but I prefer to create my own.
I've run in to a problem with using lists and need some advice.

The SLA values are stored in a lookup table containing the threshold for each user interaction and the file is called performanceApdex.csv, here is a sample:

uea=UserEventAction T=threshold


utt = UserTotalTime

This is my search:

index=prod_index sourcetype=apache_access "/collectStats*" | table uea, utt | inputlookup append=t performanceApdex.csv | stats list(utt) as UTT, first(T) as T by uea | mvexpand UTT | stats count(eval(UTT<=T)) as Satisfied, count(eval((UTT>T) AND (UTT<4*T))) as Tolerated, count(eval(UTT>4*T)) as Frustrated | eval Total=(Satisfied+Tolerated+Frustrated) | eval ApdexScore=round((Satisfied+(Tolerated/2))/Total,2) | eval %Satisfied = round(((Satisfied/Total)*100),1) | eval %Tolerated = round(((Tolerated/Total)*100),1) | eval %Frustrated = round(((Frustrated/Total)*100),1) | fields - Satisfied, Tolerated, Frustrated, Total

When I run the search, I get the warning message in the Job drop-down located under the search field:

"'stats' command: limit for values of field 'utt' reached. Some values may have been truncated or ignored."

I need to get ALL user response times (utt), but the order is not important. Is there a better way to do this search?

Best regards Patrik

You could alter the size of the list returned in limits.conf.
