Hi,
I have an ASP.NET 4.5 (Web API) web application hosted in IIS on Windows Server 2008 R2. This web application is hosted in it's own application pool using the Integrated pipeline.
I am trying to use Performance Monitor to capture the ammount of memory and IO pressure of the application.
eg:
- How much memory (managed or otherwise) is the application consuming
- How much IO work (request data in / response data out - not writing to disk) is the application performing at any given second.
I with to capture these metrics so that I can gauge performance benefits of various enhancements we have to our system.
I am not interested in requests per second style load testing - this will be handled separately.
Problem: I am struggling to identify the correct performance counters to use to capture the above metrics.
There are many different counters that relate to memory usage and all of the ones I have tried do not seem change... even when I upload a 1GB file to my application.
For IO pressure I am using IO Read / Write (sec) counters under the Process object... but if I'm honest I'm only guessing.
Can anyone point me in the right direction?
