How to rank data based on field value?

s20071035 — Thu, 26 Mar 2020 13:06:44 GMT

I've got data say in following format (*there may be more than three types of exception)

     Name,Exception,count
     Jack,Null Pointer Exception,10
     Jack,Number Format Exception,10
     Jack,Other Exception,10
     Tom,Null Pointer Exception,20
     Tom,Number Format Exception,20
     Tom,Other Exception,20
     Dave,Null Pointer Exception,30
     Dave,Number Format Exception,30
     Dave,Other Exception,30

Required output is something like:

Name, Rank for Null Pointer Exception, Rank for Number format Exception...
Jack , 3 , 3 , 3
Tom , 2 , 2 , 2
Dave , 1 , 1 , 1

Any simple SPL can you suggest? Thank you.

Like this:

|makeresults | eval _raw="Name,Exception,count
Jack,Null Pointer Exception,10
Jack,Number Format Exception,10
Jack,Other Exception,10
Tom,Null Pointer Exception,20
Tom,Number Format Exception,20
Tom,Other Exception,20
Dave,Null Pointer Exception,30
Dave,Number Format Exception,30
Dave,Other Exception,30"
| multikv forceheader=1

| rename COMMENT AS "Everything above generates sample event data; everything below is your solution"

| stats sum(count) AS count BY Name Exception
| sort 0 - count
| streamstats count AS rank BY Exception
| rename COMMENT AS "Handle ties"
| eventstats first(rank) AS rank BY count
| chart first(rank) BY Name Exception
| rename *Exception AS "rank for *Exception"
