Asp Forum - [ANN] god 0.2.0 released

A lot of work has gone into god since the last release. Say goodbye to
polling for process status--support for event based conditions via
kqueue/netlink has been added (thanks Kevin Clark)! Only a few events
are currently supported (most prominently process exit), but the way is
now open for the addition of other events. A new, advanced syntax is
available (in addition to the familiar simple syntax) that gives you
full power over the new state based lifecycle of your Watches. Updated
documentation is available on the website:

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 default
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_running) do |c|
c.interval = 5 # seconds
c.running = false
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

It's where the bad projects go when they die.

No, that would be RubyGehenna. We just don't say so because we
wouldn't want to be insensitive to our superstitiously-correct
friends, now would we?

Man . . . I want to register rubygorge.org now. I just don't know what
I'd do with it.

That's not as funny . . . but I'd like to see what someone does with it,
if it gets registered and used.

What a complete moron! The viewers left wondering what the other crime
means it was a cliffhanger ... but you continue believing whatever utter
nonsense you want to delude yourself with. As I said, I gave you the
facts, whether or not you believe them is your problem. I'm done. :-
