Re: monit not catching failed ping test

monit checks the service in intervals given by the "set daemon <x>" settings. If the interval between checks is long or the check is blocked by some service timeout/action, then the interval can be longer.

Please can you check the "set daemon" settings and run monit in debug mode?:

1.) stop monit
2.) monit -vI

Best regards,

Good morning.
     I have a small monitoring setup with m/monit 3.7.2, using monit 5.25.2 as the agent.   There are a couple of systems that I cannot install monit on that I still need to be aware of any downtime, so I have added them as ping checks in the monitrc on the host where I installed m/monit.  Yesterday, one of those remote systems went down, but monit and m/monit didn’t report an alert for it and still have its status as OK.  Using anonymized information,  the entry in the monitrc on host1 is:
CHECK HOST host2_ping with ADDRESS
And from the command line on host1:
host1% monit status host2_ping
Monit 5.25.2 uptime: 48d 19h 8m
Remote Host 'host2_ping'
  status                       OK
  monitoring status            Monitored
  monitoring mode              active
  on reboot                    start
  ping response time           -
  data collected               Fri, 08 Mar 2019 10:41:33
host1% ping host2
PING ( 56(84) bytes of data.
From ( icmp_seq=1 Destination Host Unreachable
From ( icmp_seq=2 Destination Host Unreachable
From ( icmp_seq=3 Destination Host Unreachable
Clearly there is a disconnect between the OS-provided ping utility and what monit is seeing.   I’m sure that it’s probably a simple error in configuration, but I am not seeing what I did wrong.   Can someone please set me on the correct path?
Thank you
