Thanks for data. I think the problem could be solved by changing the /etc/hosts order so it returns the real hostname first or by asigning the hostname to real IP address (not loopback):
Current state: --8<-- 127.0.0.1 localhost.localdomain loclhost talyn.bm-home.lan talyn --8<-- Either moving the hostname to real IP (adding the line with the network IP of the given host): --8<-- 127.0.0.1 localhost.localdomain localhost x.x.x.x talyn.bm-home.lan talyn --8<-- Or switching the hostname and localhost order (retains the hostname on 127.0.0.1): --8<-- 127.0.0.1 talyn.bm-home.lan talyn localhost.localdomain localhost --8<-- Your other machines probably uses one of the above setups. On Monit side we can modify the hostname assignment to skip the localhost entries returned by the resolver and use the first non-localhost name. This will allow to pickup the hostname even if it is present in the /etc/hosts past the "localhost" entries.
