Re: monitoring the number of processes

[Stephen Berg (Contractor)]

I wrote up a script (/usr/local/sbin/processname) that generates a "0" 
return code if there is one process running, otherwise it returns "1".  
So if the daemon is not running or has more than 1 process I should get 
a 0.  That's good so either state of not running and running more than 
one instance should generate a restart.

In /etc/monit.d/processname I have:

check program processname with path "/usr/local/sbin/processname"
    if status != 0 then
    start program = "/usr/sbin/service processname start"
    stop program = "/usr/sbin/service processname stop"
    restart

When I test using "monit -t" I get:

/etc/monit.d/processname:3: syntax error '/usr/sbin/service'

This is the first time I've tried to do any custom setup in monit so I'm 
betting I'm just not getting the right syntax is just the right spot.
