 1 | Munin IRC Stats
 2 | ===============
 3 | 
 4 | A plugin for Munin which graphs the number of connected clients and channels on an
 5 | IRC server.
 6 | 
 7 | Configure the IRC server settings in config.json, and symlink as `/etc/munin/plugins/irc`
 8 | and Munin will begin drawing graphs.
 9 |

11 | 
12 |     {
13 |       "server": "irc.freenode.net",
14 |       "port": 6667,
15 |       "nick": "munin",
16 |       "username": "munin",
17 |       "serverPassword": ""
