How to create a pie chart after applying math on column values extracted?

[sjs]

Hey people, my requirement is as such

I have extracted these columns from my data using the query 

my query | rex "filterExecutionTime=(?<FET>[^,]+)" | rex "ddbWriteExecutionTime=(?<ddbET>[^)]+)" | rex "EXECUTION_TIME : (?<totalTime>[^ ms]+)" | eval buildAndTearDowTime=(tonumber(FET)) + (tonumber(ddbET)) |table totalTime FET ddbET buildAndTearDownTime

I want to have buildAndTearDown as totalTime - (FET+ ddbET)

once I have all the three values required (FET, ddbET, buildAndTearDown) I want to put these values in a pie chart.

Thanks 😊

Hi @sjs ,

You have a typo in your eval , you are missing n in buildAndTearDown, please try below;

my query 
| rex "filterExecutionTime=(?<FET>[^,]+)" 
| rex "ddbWriteExecutionTime=(?<ddbET>[^)]+)" 
| rex "EXECUTION_TIME : (?<totalTime>[^ ms]+)" 
| eval buildAndTearDownTime=(tonumber(FET)) + (tonumber(ddbET)) 
| table totalTime FET ddbET buildAndTearDownTime

[sjs]

Hey people, Can I get some help

[sjs]

This statement 

eval buildAndTearDowTime=(tonumber(FET)) + (tonumber(ddbET))

is giving me null value
