CRM Diagnostics Page

When troubleshooting CRM performance issues everyone typically wants to point fingers at the servers – whether it be SQL, CRM, or even SSRS – but a commonly overlooked factor is the network. Not known to everyone is a tool built into CRM called the CRM Diagnostics Page. It is basically a very simple way to check network performance. To access the CRM Diagnostics Page simply go to:


This will land you at a page that looks like the following:

On this page, you can clearly see the series of tests available but what are they?

1. Latency Test
This calculates the average time taken to download a small text file 20 times. The file downloaded from the CRM server is /_static/Tools/Diagnostics/smallfile.txt. CRM is designed to work best with latency under 150 milliseconds. Latency can be a huge factor in performance for offices far away the CRM server’s location.

2. Bandwidth Test
The bandwidth test downloads image files and records the speeds. The recorded speeds are averaged together and provided in the results summary. Bandwidth should ideally be higher than 50 KB/sec. This test, along with the Latency Test, are the most helpful on this page.

3. Browser Info
This is a JavaScript pull of the local browser details such as browser name, version, cookie status, operating system and the user-agent string.

4. IP Address
This is the IP address of the client computer as known to the server. The IP address is server-side dynamic and represents the IP address which was used to contact the server.

5. JavaScript tests
The series of JavaScript tests times loops and returns their execution time. They are essentially just memory/CPU stress tests on the client machine.

6. Organization Info
Provides general server information- organization name, time on server and client and URL.

This is also a neat little secret: http(s)://<YourCRMServerURL>/home/home_debug.aspx.
It has some of the same information as the diagnostics page - Not overly helpful but can possibly come in handy troubleshooting. I find it just to be a nice, concise page for deployment information to help with documentation.
