Whiting a group by query for logparser to look for a pattern

Question

I already asked this on another forum but I didn't get any answers or ideas. What I am looking to do is to look for a patterns in my log files when a specific scenario is occurring.

I would like to know if a user session is getting timed out prior to 10 minutes where the last GET Request is to timeout.aspx I was able to parse out the aspnetsessionid and group by that, but I am missing another part. I need to subtract the time taken from start to end of that session.

Here is how I started

   SELECT  
    TO_STRING(time, 'm') as mins,
        EXTRACT_TOKEN(EXTRACT_TOKEN(cs(Cookie), 1, 'ASP.NET_SessionId='), 0, ';+__ut') as    ASPNETSESSIONID From C:\logs\ex11*.log
    GROUP BY ASPNETSESSIONID, mins

Here is an example of a case where a timeout is ocuring prior to 10 min

Line Number Date    Time    Client-IP   Server IP   Server Port Request Verb    Request URI, ASPNETSessionID

Answer 1

Although there is an accepted answer on the question I would say: This logic is not possible to implement with logparser.
