Re: Seperate heartbeat frequency and service monitoring interval

[Martin Konečný]

msgpack is much faster than json:

Especially if numbers are involved, since in that case, the number is transmitted as a number (one or two bytes) instead of a string.

Hello,

we plan to switch to JSON and gzip transport in the future.

As a workaround you can modify Monit to send the heartbeat less frequently ... the (polltime) schedule is in heartbeat() in src/monit.c:

--8<--

                        wait.tv_sec = time(NULL) + Run.polltime;

--8<--

You can modify it to run once per hour this way:

--8<--

                        wait.tv_sec = time(NULL) + 3600;

--8<--

On M/Monit side just extend the "acceptable report skew" settings of the given host to allow for longer communication pause (cycles count based), otherwise M/Monit will fire the heartbeat event => if your poll time is 60 seconds, set the "acceptable report skew" (in host admin) to ca. 61 (i.e. wait for 61 cycles * 60 s before firing heartbeat event)

Martin

Hello All,

 

Is it possible to have a separate heartbeat frequency and service monitoring interval?  I have a low bandwidth situation and need to reduce the frequency of updates from Monit to MMonit.  This interaction is using roughly 5K per minute to transmit the XML payload.  I would like to reduce this to once or twice an hour but I need to keep the 60 second response to a service outage.  Also, are there any tips on reducing the size of the payload, JSON perhaps?

 

Thanks,
