Re: Auto-reload of configuration files

[Eric Montellese]

I may have some availability to contribute if watching a directory for any file changes is desired.  

This can be accomplished with inotify.

http://man7.org/linux/man-pages/man7/inotify.7.html

Could you also please confirm that it is reasonable to send a SIGHUP to monit from monit itself?

Also, thank you for monit -- it's a terrific tool.

Best,

Eric

Hell Eric,
yes, file updates can not monitored by the folder timestamp.
But you can add and delete an additional dummy file to change the folder
timestamp.
I have no idea how to implement your requirements, sorry.

I add and delete configuration files into the config folder, only. This
fits to my requiremts of a dynamic configuration for monit.

With regard,
Lutz
