Descartes Cookbook

Build Status

Descartes is a collaborative dashboard and graph management tool for Graphite. This cookbook installs and manages a Descartes instance and offers a number of LWRP's you can use to manage graphs in the graph system. Mix together some collectd with write_graphite, maybe a side of statsd or riemann, and even some artisinal data collection scripts, then toss in this Descartes cookbook and you're ready to serve up some serious monitoring love.

node.set['descartes']['session_secret'] = 'supersecretstuffnohints'
node.set['descartes']['graphite_url']   = 'http://graphite.company.com'
node.set['descartes']['oauth_provider'] = 'google'
node.set['descartes']['api_key'] = 'mycompanysecret'
node.set['descartes']['google_oauth_domain'] = 'company.com'

node.set['descartes']['host_name'] = 'descartes.company.com'

include_recipe 'descartes'
include_recipe 'descartes::proxy_apache2'
