I am trying to parse the IIS Log files to get some pertinent information about my ASP.NET application. I am trying to get some performance data by looking at the time-taken field in the logs. I can read these in and group them by page/query-string, etc. and get min, max, avg times for each page. However, the data is being skewed by the inclusion of the ASP "postback" loads of pages, which tend to be very quick compared to the "real" load times for each page. Does anyone have any idea how to distinguish between these "types" of page loads? I cannot just include only GET's, because I have some pages that use POST.
I am using IIS 5.1 with .NET Framework 1.1. I can change my logs to include any of the extended properties supported by IIS 5.
