Redmon

Simple sinatra based dashbord for redis. After seeing the fnordmetric project I was inspired to write this. Some of the ideas there have be carried over here.

Watch your redis server live.

Interact with redis using a familiar cli interface.

Dynamically update your server configuration.

Installation

Redmon is available as a RubyGem:

gem install redmon

Usage

$ redmon -h
Usage: /Users/sean/codez/steelThread/redmon/vendor/ruby/1.9.1/bin/redmon (options)
    -a, --address ADDRESS            The thin bind address for the app (default: 0.0.0.0)
    -n, --namespace NAMESPACE        The root Redis namespace (default: redmon)
    -i, --interval SECS              Poll interval in secs for the worker (default: 10)
    -p, --port PORT                  The thin bind port for the app (default: 4567)
    -r, --redis URL                  The Redis url for monitor (default: redis://127.0.0.1:6379)
    -s, --secure CREDENTIALS         Use basic auth. Colon separated credentials, eg admin:admin.
        --no-app                     Do not run the web app to present stats
        --no-worker                  Do not run a worker to collect the stats

$ redmon
>> Thin web server (v1.3.1 codename Triple Espresso)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:4567, CTRL+C to stop
[12-03-10 15:49:40] listening on http#0.0.0.0:4567

If you want to simulate a weak load on redis

$ ruby load_sim.rb

Open your browser to 0.0.0.0:4567

Using in a Rails application

Add to Gemfile:

gem 'redmon', require: false

Add to config/routes.rb:

require 'redmon/app'
mount Redmon::App => '/redmon'

You can configure the Redmon using an initializer config/initializers/redmon.rb:

Redmon.configure do |config|
  config.redis_url = 'redis://127.0.0.1:6379'
  config.namespace = 'redmon'
end

This will mount the Redmon application to the /redmon/ path. The trailing slash is important. The worker that gathers the redis info stats will not be started when Redmon is mounted. In order to get a worker running inside of your Rails app you can try this Railtie based approach.
