Re: Auto-reload of configuration files

[leif]

Could you use the "check program" functionality?  Have monit run a script which reads the monit control file and in a deterministic manner follows includes and generates a checksum.  If the final checksum differs from the previous cycle, run "monit -t" and conditionally send SIGHUP?  This seems like it would be more of a self-contained solution in the sense that it wouldn't require wrapping monit's initialization or external daemons, and wouldn't be dependent on inotify.

Thanks for the input -

Yes, we're looking to automatically reload monit's configuration if a monit configuration file changes.  The idea being that various (pre-tested) applications with their own monit configurations can be added and removed automatically.

One option that we've tested is to have a separate process (or wrapper) that runs inotify on the configuration files, and sends SIGHUP to monit if a change is detected.  This works, but it seems a shame to add a separate monitor for monit.

Hello Eric,
are you interresting in doing an config reload only.

I do monitoring some application server folder to find new application
to be configured to monit and add the additional configuration based on
a template.
After I create a new config file based on the template I use the syntax
check to check the new config file. If the check will be passed, the new
config will be loaded by reinitializing monit.

This is my way, but I never monitor the monit config folder to find
changes and do an automatic reload.
