Re: Troubleshooting - verbose not verbose enough

[Martin Pala]

Monit purges the environment variables for security reasons and sets spartan path: PATH=/bin:/usr/bin:/sbin:/usr/sbin

You can log the output of executed script this way:

    start program = "/bin/bash -c '/usr/bin/myscript blabla >> /tmp/myscript.out 2>&1'"

Hi. I'm attempting to troubleshoot a process that won't start under Monit. I'm using a system-wide install of RVM and have followed all the steps outlined in this thread:

None of the suggestions there worked for me, and I'm having trouble finding any useful output to figure out why. I started Monit in verbose mode and tailed the log, however the debug statements weren't very helpful. I got stuff like this (path has been truncated with ...) :

I'd like to see what the output was when Monit called the startup command. Any way to do that?

Thanks!
