Re: [monit] Apps start from monit - problem

[Martin Pala]

Monit sets sandbox environment consisting of:

PATH=/bin:/usr/bin:/sbin:/usr/sbin

and several  MONIT_* variables which inform the program being  
executed about the event and allow to customize the according to  
context.

It is possible that your command line environment contains extra  
environment variables which are required by mongrel configuration,  
which are not set when starting via monit. You can add these  
variables to the startup script.
