You can disable starting of services from by init in given run levels and let monit start them.

By default the monitoring mode is automatic which will enable monitoring of all service by default and if the service is not running, it will start it. The "start all" command is thus not necessary unless you have some services in manual monitoring mode.

There are important fixes in upcoming monit-5.0 (you can get beta here:

It fixes the described race condition where monit tried to start the service but before the start was finished, the monitoring thread detected that the service is not running and tried to restart it (in parallel to pending start action).

I am trying to find the right way to start monit on my system.
My requirements are simple: start all services at boot time, stop all of

Using monit 4.10.1

The documentation recommends running monit from init. I find this
problematic as it lacks the flexibility of /etc/rc.d scripts to determine
the order of execution. I can choose to run monit before or after init
scripts, but nowhere in between.
Is there any way around it ?

Assuming there isn't, I have a few issues with my /etc/init.d/monit script

The FAQ includes a comment (suggested by myself...) to "start all" as part
of the init script.
Should this be called before or after starting the monit daemon ?
I tried both combination. In both I seem to run into situations where, by the time the second command runs, services haven't completed their startup,
and the second command tries to restart the service.
I tried this with both "start all" and "monitor all", with similar results.

What's the clean solution ?
Perhaps to remove the state file and then start the daemon ? Will that do it ? When monit starts, in the lack of a state file, does it assume that all
services are monitored and should be started ?

Thanks in advance
