I haven’t used monit but there are some significant flaws with supervisord. Programs should run in the foreground This means you can’t just execute /etc/init.d/apache2 start. Most times you can just write a one liner e.g. “source /etc/apache2/envvars && exec /usr/sbin/apache2 -DFOREGROUND” but sometimes you need your own wrapper script. The problem with wrapper scripts … Read more
From your mention of Upstart I will assume that this question is for a service being run on an Ubuntu server. On an Ubuntu server an upstart job is really the simplest and most convenient option for creating an always on service that starts up at the right time and can be stopped or reloaded … Read more

Upstart makes it easy to deamonize node.js and Monit comes packed with tons of useful app checks including memory usage, http requests, cpu usage, … This is an example of the most basic setup you can get. You could also easily add another monit config (with the … Read more
God leaks memory pretty badly so I chose Monit for my VPS. Monit runs at about 2MB of RAM constantly, whereas my god install running on Ruby 1.8.6 leaked out to about 60MB of RAM in about 36 hours. I didn’t want to monitor my system monitoring tool so I scrapped God and went over … Read more
Here is how I got this working. Use the collectiveidea fork of delayed_job besides being actively maintained, this version has a nice script/delayed_job daemon you can use with monit. Railscasts has a good episode about this version of delayed_job (ASCIICasts version). This script also has some other nice features, like the ability to run multiple … Read more
