We are in the process of rolling out VMAN and I realized that I don't really know how to monitor the viability of the application via SAM.
On the master appliance there is the hyper9 user running the tomcat instance and a postgres user running a bunch of postgres instances. The federated collectors just have the hyper9 user running the tomcat instance.
Anything else? Do you monitor for CPU utilization, memory utilization, up/down status for the application?
