Munin

Install

To add a machine as a munin node, which can then be interrogated by the munin master (typically Quacker):

$ sudo yum install munin-node

Configure

To allow Quacker to access this munin node:

$ sudo -i
$ cd /etc/munin
$ vi munin-node.conf

cidr_allow <subnet>

Current AWS subnet is: 172.31.0.0/16

Restart

If munin-node becomes unresponsive, try:

/etc/init.d/munin-node restart
