How to perfom math calculations

I am trying to figure out how to take two searches and divide their results to create a dial chart showing the percentage of breached records.

index=itsm sourcetype=sm9_incident | dedup NUMBER | search assignmentGroup="WG1555" AND isBreached="t" AND status="Closed" |stats count

index=itsm sourcetype=sm9_incident | dedup NUMBER | search assignmentGroup="WG1555" AND status="Closed" | stats count

Hi bvenom28,

try something like this:

index=itsm sourcetype=sm9_incident assignmentGroup="WG1555" | dedup NUMBER | eventstats count(eval(isBreached="t" AND status="Closed")) as isBreachedCount count(eval(status="Closed")) as ClosedCount | eval myPrec=isBreachedCount*100/ClosedCount | table myPrec

cheers, MuS

bvenom28,

your searches where really not well formed:

index=itsm sourcetype=sm9_incident | dedup NUMBER | search assignmentGroup="WG1555" AND isBreached="t" AND status="Closed" |stats count

The search terms should always be places at the beginning of the search, unless you really need to filter out results based on same valued calculated in a stats or eval statement.

As correctly MuS wrote, the assignmentGroup="WG1555" condition has been placed right at the beginning, and he wisely used the "count(eval('condition')) trick to summarize values of events matching a certain condition.
