Activity monitoring provides visibility into the applications that are in use on the Windows desktop virtual machines that are managed by vCenter. This visibility helps ensure that security policies at your organization are being enforced correctly.
A security policy may mandate who is allowed access to what applications. The cloud administrator can generate Activity Monitoring reports to see if the IP based firewall rule that they set is doing the intended work. By providing user and application level detail, activity monitoring translates high level security policies to low level IP address and network based implementation.
Once you enable data collection for Activity Monitoring, you can run reports to view inbound traffic (such as virtual machines being accessed by users) as well as outbound traffic (resource utilization, interaction between inventory containers, and AD groups that accessed a server).
Activity monitoring is not supported on Linux VMs.
