[OpenSIPS-Users] Monit error under OpenSIPS 1.6.3 and Opensips-cp 4

[Dave Singer]

You may not have monit running as a service. Check the current status of
monit:
  monit status
It will tell you if it is running.
If it is not start it with:
  /etc/init.d/monit start
I primarily use centos and fedora but I think that will work with debian
systems too.
I think that the default config does not have the daemon set to listen for
communication. It needs this for commands like "monit status" and "monit
monitor opensips" and "monit unmonitor opensips"
something like this:
  set httpd port 2812 and
     use address localhost  # only accept connection from localhost
     allow localhost
Also you don't want to use the same call to the init.d script that is used
to start it up regularly otherwise you get a loop going or at least double
notify of (un)monitor actions.
What I do for the opensips portion of the monit config is have it call
/etc/init.d/opensips monit_start.
Then in /etc/init.d/opensips I have it catch that arg and not tell monit to
monitor but call the regular start function. When it gets the regular start
arg it calls the regular start function and then tells monit to start
monitoring it.
Also when the init.d script gets a restart command I don't update monit It
checks the pid file itself and realizes that the pid has changed and sends a
message to that affect rather then two messages, one that it us unmonitoring
and one that it is monitoring.
I've attached the /etc/init.d/opensips that I'm currently using.

Don't forget to make sure that the monit daemon will start on next reboot.

The attached init.d/opensips script uses some of redhats conventions for
displaying success/failure and adjust the working directory according to
your install. But I think overall it should be fairly portable to other
distros.

Note. Many of the options I pass to opensips are usually set in the script.
For the passed options to work they can not be set in opensips.cfg.
You may also notice that for a restart it validates the config before
allowing a restart. It does two levels of checks, the opensips -C to verify
the syntax of the config and actually starts a minimal opensips because
sometimes there are things that will make it not work even when the syntax
checks out.
The test run listens on lo:2056 so beware incase of conflicts. YMMV

Hope that helps.
