From the agents overview snapshot I don't see the IIS agent, AFAIK IIS and .NET agents will show separately in the agents overview. Have you followed these steps in instrumenting the IIS server
From the agent overview snapshot which you have provided I could see the purepaths are getting captured on one of the secondary agent - the purepath count is 49. so you can see the data.
I believe you are selecting the proper system profile under the Monitoring default Dashboard, if it is so then you need to make sure the time frame which you have selected as well. Paste me the snapshot on which you are looking for the data, if it's not helpful.
