God is watching

We’ve been using monit at Engine Yard on thousands of machines with a great deal of success. Sometimes it can get itself into a weird situation where it lets you down, but by far it does its job exceptionally. When I was setting up process monitoring for a merb app of my own; the logging capabilities of monit really let me down.  I had weird stuff happening because the environment was being cleared and I couldn’t track down exactly WHY my merbs kept aborting. So I gave God a try and I really like it. I run god under init and here’s the basics for setting it up on an EY slice or any Linux box for that matter.

Setting Things Up

Now all you have to do is drop god configs in /etc/god and you’re good to go. You should be able to see some meaningful log output in /var/log/syslog.

But it leaks memory!?!

Some of my coworkers are still hesitant about it because of the memory consumption and leaks they’ve seen. I kill god once a day with a cron job. :)

p.s. Anyone have a better god config for merb processes? Here’s mine
