Re: Hosts on M/Monit keep going offline and online at regular intervals

[Abdul Munim Kazia]

No, I don't get timeouts in the monit log. Only frequent "No report from Monit" and "Monit status report received successfully" events in m/monit. Anyway, I am keeping an eye on my hosts after changing the report skew setting. 

Thanks for your help

The timeout option can be increased like this:

        set mmonit http://address@hidden:192.168.48.1:8080/collector with timeout 60 seconds

Rising the timeout will make sense only if you'll find timeout errors in Monit log.

Martin

The report comes in a few seconds and the host becomes green again. This happens fairly regularly, and it happens to a different set of hosts every time. All the hosts and the m/monit host itself are hosted in the same data center, so I don't think that network latency is an issue.
