STATS function

Hi, Is there a way to find out the max response time during a 30-minute bucket and its associated url from the web server log?

I tried to use the search string below but seems to be not working. Please advise. Thanks!

sourcetype="access_log" | bucket _time span=30m | STATS max(TotalResponseTime), url by _time

Does .... STATS max(TotalResponseTime) by _time url work for you?
I think its trying to use 'url' as an argument?

Unfortunately, this is not something I need. I only care about the url with max response time.
I have various types of urls in the web access log. If I add the url at the end of the search string, I will have too many results.

Use eventstats to preserve the url and then grab only those urls where the response time equals the max. If there are multiple urls with the same TotalResponseTime, then you could still get multiple urls for the same time range, but that would seem unlikely.

sourcetype="access_log" | bucket _time span=30m | eventstats max(TotalResponseTime) as maxtim by _time | where TotalResponseTime=maxtim |table _time,TotalResponseTime,url
