Hello Martin,
I made the changes per your request.
The monit_stop.out file was created but it is empty.
Stop command failed to stop the service.
The section from monitrc follows:
check process staledaemon with pidfile /var/run/staledaemon.php.pid
start program = "/root/startdaemon.sh staledaemon" with timeout 60
seconds
stop program = "/usr/local/bin/bash -c '/root/stopdaemon.sh
staledaemon >> /tmp/monit_stop.out 2>&1' "
if cpu > 60% for 2 cycles then alert
if cpu > 80% for 5 cycles then alert
if cpu > 80% for 5 cycles then restart
if loadavg(5min) greater than 16 for 8 cycles then alert
if loadavg(5min) greater than 16 for 10 cycles then restart
if children < 2 for 2 cycles then restart
Previously I had been using webmin to monitor the processes, and
everything worked fine with it. I decided to move to monit because if
the higher granularity and functionality. I am running the tests every
30 seconds. Also, I have one test which monitors a process by name
which seem to think the process is going down - not certain if it is or
not, still checking. In this case the process is pgagent (the
PostgreSQL agent). I had never seen it go down before, so will do more
checks, but I had seen a thread concerning some issues with monitoring a
process by name.

Hello,
please can you add the start/stop statement which you use for the
stopdaemon.sh in monit configuration file?
You can log the script output this way:
stop program = "/bin/bash -c '/root/stopdaemon.sh staledaemon
>>/tmp/monit_stop.out 2>&1'"
Regards,
Martin

I am having a strange issue stopping a group of services (daemons
written in PHP).
OS is FreeBSD 8.1, monit version is 5.2.4.
I have tried various approaches.
I tried running it through a stopdaemon.sh which looks as follows:
#!/bin/sh
#stop a php daemon
mydaemon="$1.php"
killstring="/bin/ps -aux | /usr/bin/grep 'php $mydaemon' | /usr/bin/grep
-v stopdaemon | /usr/bin/grep -v grep | /usr/binawk ' {print \$2}' |
/usr/bin/xargs /bin/kill -s KILL && sleep 10"
eval $killstring
Running this from the command line works fine. Running it from within
monit fails - not sure why.
Checking the processes which run as the stop script is called I see the
following, which indicates it was called properly and with root access:
root 61480 0.6 0.0 8264 1784 ?? S 5:28PM 0:00.01
/bin/sh /root/stopdaemon.sh staledaemon
root 60597 0.0 0.1 99664 21116 ?? Ss 5:27PM 0:00.03
/usr/local/bin/php staledaemon.php
root 60598 0.0 0.1 99664 21200 ?? I 5:27PM 0:00.01
/usr/local/bin/php staledaemon.php
root 61620 0.0 0.1 99664 21204 ?? S 5:28PM 0:00.00
/usr/local/bin/php staledaemon.php
Launching the script from the command line works fine. Any ideas will
be deeply appreciated, since it is critical that I be able to stop the
processes.
I monitor the number of processes which are running, and if they fall
below a certain level I need to restart the service, since each process
in the service has its own functionality.
Any assistance will be deeply appreciated.
