Good Afternoon, 

Please, could you support me with this issue. We have two linux monitor with the message "System is Down. Ping test failed."

1. From AppManager server I have response from both servers.

Ping Test passed

Telnet Test passed

2. The IPs are in the hosts file from AppMAnager. 

3. From servers the appmanager had response. 

There is another point that I need check?

Thanks & Regards!
