I am doing some email cleanup and got a request to write a post about how to use the HTTPERR logs.
I thought long and hard about what I could write that would add value. There is a really good KB article on the topic http://support.microsoft.com/default.aspx?scid=kb;en-us;820729 that goes through how to set it up properly and what all the error codes mean, and there is another good article from asp alliance on how to use LogParser to perform queries against the http error logs to sift through the data.
Since these are already out there and cover a lot of the questions I could see arise about the http error logs I will leave it at that. Feel free to comment on if you have specific questions about the HTTPERR logs that isn’t covered by those articles though…
