Splunk Search

How to edit my search to calculate failure percentage through Splunk logs?

I have logs like:
"The request failed"
"The request succeeded"
"The request failed"
"The request failed"
"The request succeeded"

I want to calculate failure % every day on the basis of the string ("failed" or "succeeded")

please help me correct this search (marked in ***):

...base search... | timechart span=1d ***eval((count("failed"))/((count("failed"))+(count ("succeeded"))))*** as failureRate

Try this:

your base search | rex "The request (?<status>\w+)" 
| timechart span=1d count(eval(status="failed")) as failed,  count(eval(status="succeeded")) as success
| eval failureRate=(failed/(failed+success))*100

Try like this

your base search | rex "The request (?<status>\w+)" | timechart span=1d count by status | eval "%failed"=round(failed*100/(failed+succeeded),1)

try something like this:

...| timechart span=1d count("failed") as failed count("succeeded") as succeeded|eval failureRate=failed/(failed+succeeded)|fields - failed - succeeded

you might need to add something like count(match(x,"failed")) into the timechart command instead of the count("failed")
