Agent on Redhat Linux 8

[itmanager@waldocountyme.g]

I have installed the Linux RMA on Redhat Linux 8, configured the rma.ini file, when I try to run a test for CPU usage I am getting a response of RMA 301 timeout.

Here are the latest contents of the log file:

What exactly "Linux RMA" you are using? There are many versions.
Active RMA v.5.20 x64?

nknown command received: "nmscanon"

Looks like you set Network Discovery record for this agent on HostMonitor side. Linux agents do not support such option. Please remove that record
(menu LANs -> Network discovery)

Connection refused retry in 30s (RMA Manager)

RMA Manager is started?
Then check firewall settings, connection parameters on RMA and RMA Manager side.
