Re: Monit does not start flxlm

[Martin Pala]

Hi,

monit runs the start/stop programs in a sandbox and strips all environment 
variables (for security reasons) - it sets only the spartan path: 
"PATH=/bin:/usr/bin:/sbin:/usr/sbin"

If your script depends on some environment variable, it may fail when executed 
by monit. You can log the script output by wrapping it like this:

        start program = "/bin/bash -c '/sbin/service flexlm start >> 
/tmp/flexlm_start.log 2>&1'"

You can also pass the variables in the bash command or create some wrapper 
which will set the variables and call start.


Regards,
Martin
