The application rule manager collects information from selected virtual machines for a given period. The resultant set of flows is then analyzed by the NSX Manager, which provides you with a list of recommended firewall rules for insertion in the distributed firewall based on the flow information it gathered.
The following configuration parameters should be noted when working with the application rule manager:
- Multiple ARM sessions can be configured up to a maximum of five
- ARM can monitor up to 30 virtual machines in one session
- A session can last a maximum of seven days
