I´m facing a problem when for some reason (machine or network, I believe) a remote machine where I have RMA installed is loosing connection do the machine where HM is running. As a result, all the tests configured on the remote machine get an UNKNOWN status. Would it be possible to make tests depend on RMA status? Maybe is more logical to see only RMA status change then all the tests wich depend on it.
Sure, you can do that. Setup TCP test to monitor agent and use this item as master test.
Also you may use Ping test (ping 127.0.0.1) thru agent to monitor workability of the agent.
