Configuring IIS agent with more than one app pool
Hi,
We have a web application with front end running in IIS and has two application pools (main website and one for mobile version of the site). UEM is enabled in the profile and ISAPI filter is applied only on the main app pool (we dont want UEM on the mobile website). We see that all requests come through the IIS agent for the main app pool where as the requests to mobile app pool is coming directly to the .net agent. Should that also come through the IIS agent? We use basic settings for the IIS agent (changed the default name and provided the right collector:port in the ini file). How can we configure the IIS agent so that the request to all app pools come through the IIS agent and then go to the .net agent? Also we dont want UEM injection in all app pools.
Thanks,

Sreerag,
If you want to collect web tier statistics, then you need the web tier module. Since you are talking about the ISAPI filter I assume you have IIS 6. For IIS 7 you would use the native HTTP module. Install whichever is appropriate (ISAPI filter in your case) and this will then be collecting data for that tier. See the doc for this HERE.
As for UEM: define the appropriate dynaTrace "Applications". In your UEM configuration in the system profile, create a UEM configuration for the main site that enables UEM, and a separate UEM configuration for the mobile site that does not enable UEM. See the doc for these topics HERE (Applications) and HERE (UEM configuration).

Hi Rob,
We have the UEM and applications configured for the website. The part not clear is why the requests to two app pools in the same IIS server is not coming through the dynatrace IIS agent. Now for one app pool we see the response time from the IIS and for the other one we see only from the .Net side and we dont know how much time it takes in the IIS for those requests.
Thanks,

Have you checked your Agents Overview? Do both Agents show up? Do you have enough licenses for both?
Hi Sreerag,
You need the ISAPI module on each site. You said you have it on one site but not the other. That's why you're seeing one PP start at the WebServer tier (where you have the module) and in the .NET tier (where you do not have the module). When you install the ISAPI iflter on the other site you will start to see it pick up the PP at the Web tier.

Thanks Rob, that seems to be the solution i was looking for. I thought of applying the ISAPI filter to both sites but wanted to make sure i dont inject the UEM javascript on the mobile site pages. I need to try this out.
Thanks,

The solution of adding ISAPI filter worked, now we see the IIS layer for both app pool requests.
