Client Network Traffic tests
These postings are provided "AS IS" with no warranties, and confer no rights.
The following information is for example purposes only. Do not rely on this information for a production deployment. These are meant to show the areas you should test for when evaluating ConfigMgr client activity impact on your network before going into production. The results are specific to the below ConfigMgr configuration and will vary from environment to environment.
UPDATE (22/04/2013): The System Center 2012 Configuration Manager version of this post can be found here: https://aka.ms/pwlunk
To perform this sort of testing you can use NetMon 3.3, and the Top Users Netmon Expert. Basically, the process is:
- Start Capture (easiest in Mixed Mode)
- Perform Activity
- Stop Capture
- Run the Top Users expert
