## Based on Redis module code v0.08 2009/from http://svn.rot13.org/index.cgi/Redis
##
## Installation process:
##
## 1. Download the plugin to your plugins directory (e.g. /usr/share/munin/plugins)
## 2. Create 3 symlinks at the directory that us used by munin for plugins detection (e.g. /etc/munin/plugins): redis_connected_clients, redis_per_sec and and redis_used_memory
## 3. Edit plugin-conf.d/munin-node if it is needed (env.host and env.port variables are accepted; set env.password for password protected Redis server)
## 4. Restart munin-node service

=head CONFIGURATION
Based on Redis module code v0.08 2009/from http://svn.rot13.org/index.cgi/Redis
Installation process:
1. Download the plugin to your plugins directory (e.g. /usr/share/munin/plugins)
2. Symlink it to your configuration directory (e.g. ln -s /usr/share/munin/plugins/redis /etc/munin/plugins/redis)
3. Edit plugin-conf.d/munin-node with the options to connect to your redis instances (see below for an example)
4. Restart munin-node service
Example config
[redis]
env.host1 127.0.0.1
env.port1 6379
env.password1 password
env.title_prefix1 redis-1
env.host2 /run/redis.sock
env.title_prefix2 redis-2
Each host should be specified with at least a host or unixsocket variable suffixed with
a number, the first being 1, the second being 2 etc. They must be in sequence.
Other options are:
* port - the redis port to connect to
* password - the password to use with the AUTH command
* title_prefix - a prefix to put before the title of the graph, this is strongly recommended for multiple instances
Graphs:
This generates multigraphs for:
* Connected clients
* Key Hit vs Miss ratio
* Keys per second, hits/misses/expirations/evictions
* Replication backlog
* Replication lag
* Request per second
* Total number of keys and keys with expires
* Used memory
