Using a stats avg function after an eval case command to categorise

Hi,

I have a requirement where we need to categorise events based on the url into 4 separate categories, then calculate the average response time for each category. Finally we want to display all the averages by category together in a stats table, is there an easy way to do this?

Hi @ebs,

the problem is to find a rule to categorize urls, if e.g. you have this rule:

in the uri field you have

localhost/* --> Cat. A

community/* --> Cat. B

splunk.com/ --> Cat. C

others--> Cat. D

you can try something like this:

index=your_index
| eventstats count As total
| eval type="D"
| eval type=case(match(uri,"localhost"),"A",match(uri,"community"),"B", match(uri,"splunk.com"),"C")
| stats avg(response_time) AS response_time count values(total) AS total BY type
| eval perc=round(count/total*100,2)
| table type response_time perc

Ciao.

Giuseppe
