Re: scheduler on Monit

[Martin Pala]

There is no default settings, it must be explicitly set. The value depends on your needs - to detect errors quickly, faster poll cycle is better (for example "set daemon 5" will poll each 5 seconds). If you want to reduce overhead, you can poll for example each 30 seconds: "set daemon 30" (or more)

Thanks, may I know what's the default setting and suggested setting for scheduler job on Monit?

Hi,

the poll cycle is set by "set daemon <number>" statement, see more details in Monit manual: https://mmonit.com/monit/documentation/monit.html#DAEMON-MODE

Best regards,

Martin

Hi All,

I read some documents and found this:

The current scheduler is poll cycle based. If a service check is scheduled with the every cron statement, Monit will check if the current time match the cron-string pattern. If it does, then the check is performed otherwise it is skipped. The cron specification does not guarantee when exactly the test will run, this depends on the default poll time and the length of the check cycle. In other words, we cannot guarantee that Monit will run on a specific time. Therefor we strongly recommend to use an asterix in the minute field or at minimum a range, e..g. 0-15. Never use a specific minute as Monit may not run on that minute.

​How could I find out what's the default poll time and the length of the check cycle?​
