## $Log$
##
## Based on resque monitoring code from https://github.com/caius/redis-munin
##
## Installation process:
##
## 1. Download the plugin to your plugins directory (e.g. /usr/share/munin/plugins)
## 2. Create 5 symlinks at the directory that is used by munin for plugins detection (e.g. /etc/munin/plugins): resque_failed, resque_queues, resque_queues_size, resque_workers_count, resque_workers_working
## 3. Edit plugin-conf.d/munin-node if it is needed (env.namespace, env.host and env.port variables are accepted)
## 4. Restart munin-node service
