Re: Monit can't find my processes!

Hi,

the start program currently requires that the program will run on the background (daemonize). You program doesn't detach and keeps monit as parent.

The following should fix it:

check process test with pidfile /Users/marmel01/Documents/foo.pid
      start program = "/bin/bash -c '/Users/marmel01/Documents/monittest.sh &'"
      stop program = "/bin/kill $(/bin/cat /Users/marmel01/Documents/foo.pid)”

Regards,
Martin

Hi folks, 

I was wondering if someone here might be able to help me out with my current monit problem. I’ve dug through the docs and I can’t seem to find what I’m doing wrong.

I’ve thrown together a small test script for monit to monitor…

#!/bin/sh

FOOPID=/Users/marmel01/Documents/foo.pid
FOODATES=/tmp/dates

/bin/echo -n $$ > $FOOPID
echo 'restarting with '$$' as pid' >> $FOODATES
ls -l $FOOPID >> $FOODATES
cat $FOOPID >> $FOODATES
while true
do
    date >> $FOODATES
    cat $FOOPID >> $FOODATES 2>&1
    sleep 3
Done


 … and a monitrc file to go with it …

#!/usr/bin/monit -c

set daemon 10                   # interval between polls, in seconds
set logfile "/tmp/monitlog.log"
set pidfile "/tmp/monitpid.pid"
set statefile "/tmp/monitstate.state"
set mailserver <REDACTED>

set httpd port 2812
    allow localhost
    allow 10.1.81.0/255.255.255.0

check process test with pidfile /Users/marmel01/Documents/foo.pid
      start program = "/Users/marmel01/Documents/monittest.sh"
      stop program = "/bin/kill $(/bin/cat /Users/marmel01/Documents/foo.pid)”

However, when I run, while the script seems to be executing perfectly well, monit won’t seem to recognise the fact!

Here’s an excerpt form monit’s log

[GMT Nov 19 12:39:30] info     : Monit daemon with PID 75079 awakened
[GMT Nov 19 12:39:53] error    : 'test' failed to start (exit status -1) -- Program /Users/marmel01/Documents/monittest.sh timed out

[GMT Nov 19 12:40:33] error    : 'test' process is not running

The pid file appears to be where it should be and is readable. I don’t know where to go from here.

I’m running the latest version of monit on Darwin.

Any help would be greatly appreciated!

Mark.
