I'm proud to announce the initial public release of god!

http://god.ruby...

WHAT IS GOD?

God is an easy to configure, easy to extend monitoring framework written
in Ruby.

Keeping your server processes and tasks running should be a simple part
of your deployment process. God aims to be the simplest, most powerful
monitoring application available.

DISCLAIMER

God is still very young, I'd love to get feedback and bug reports, but I
do not yet recommend you use it for mission critical tasks. I personally
use it in production but then I'm a daring fellow.

INSTALL

sudo gem install god

* note: currently tested only on Redhat Linux and Darwin (won't work on
Windows)

FEATURES

* Config file is written in Ruby
* Easily write your own custom conditions in Ruby
* Supports both poll and event based conditions
* Different poll conditions can have different intervals

EXAMPLE

The easiest way to understand how god will make your life better is by
looking at a sample config file. The following configuration file is
what I use at gravatar.com to keep the mongrels running:

# file: gravatar.god
# run with: god start -c /path/to/gravatar.god
#
# This is the actual config file used to keep the mongrels of
# gravatar.com running.

RAILS_ROOT = "/var/www/gravatar2/current"

God.meddle do |god|
%w{8200 8201 8202}.each do |port|
god.watch do |w|
w.name = "gravatar2-mongrel-#{port}"
w.interval = 30 # seconds
w.start = "mongrel_rails cluster::start --only #{port} -C #{RAILS_ROOT}/config/mongrel_cluster.yml"
w.stop = "mongrel_rails cluster::stop --only #{port} -C #{RAILS_ROOT}/config/mongrel_cluster.yml"
w.grace = 10 # seconds

pid_file = File.join(RAILS_ROOT, "log/mongrel.#{port}.pid")

w.behavior(:clean_pid_file) do |b|
b.pid_file = pid_file
end

w.start_if do |start|
start.condition(:process_not_running) do |c|
c.interval = 5 # seconds
c.pid_file = pid_file
end
end

w.restart_if do |restart|
restart.condition(:memory_usage) do |c|
c.pid_file = pid_file
c.above = (150 * 1024) # 150mb
c.times = [3, 5] # 3 out of 5 intervals
end

restart.condition(:cpu_usage) do |c|
c.pid_file = pid_file
c.above = 50 # percent
c.times = 5
end
end
end
end
end

Why would you pick the name "god"? Surely there are more appropriate
names for a piece of software.

Maybe "god" is simply an acronym, as proposed by Douglas Hofstadter:

You can s/djinn/daemon/ if you like.

I'm basically agnostic, but I still find "god" a poor name. It just
has too much semantic weight. An ancient name for god may carry
better, like "Deus".

My monitoring framework was called abyss, for it keeps my daemons :)

You need to add God.smite()

it's kind, forgiving, and gently chastising.

girlfriend -- it's cold, unforgiving, and doesn't tell
you what you've done wrong."

Interesting ... the Gang of Four say you shouldn't have a "god" class,
but you went and did it anyway. :)

Doesn't that just mean you have faith in God?
