Re: Httpd to triger heartbeat

[Martin Pala]

I have not checked dag rpms (its independent of monit project based on
custom spec file), but it is possible that the configuration file is
installed somewhere else by it (you can check it with 'rpm -ql monit').

It is possible to specify the path to monit control file using -c option =>
in the case that configuration is not in one of locations where monit looks
by default for it (which is ~/monitrc, ./monitrc and /etc/monitrc) or rc
script doesn't point to custom file (such as for example 'monit -c
/etc/monit/monit.conf') you will need to modify rc script properly or use
default location.

Most probably you will need to customize the configuration file for your
needs - i'm not sure whether dag rpm comes with preconfigured monit (monit
by default has no service predefined).

Your configuration doesn't contain definition for daemon mode => monit will
run the check once and exit. Here is example of simple configuration file
which sets monit to daemon mode, check just httpd process existence and root
filesystem usage:

--8<--
set daemon  5
set logfile syslog
set httpd port 2812 address 127.0.0.1 allow monit:monit
set mailserver my.mail.server
set alert address@hidden

check process httpd with pidfile /var/run/httpd.pid
  start program = "/etc/init.d/httpd start"
  stop program  = "/etc/init.d/httpd stop"

check device rootfs with path /
  if space usage > 99% then alert
  if inode usage > 99% then alert
--8<--
