Munin is about a million times easier to get working than Cacti. It's also trivial to write plugin extensions for the munin-node.

Munin-node is much easier to install using Apt or another package manager. It has many Perl dependencies :-(

apt-get install munin-node

Double-check that it included sym links to the plugins:

root@www.example.com: /etc/munin/plugins # ls -l

Use `update-rc.d` under Ubuntu/Debian or under RedHat use `chkconfig`:

# chkconfig --add munin-node
# chkconfig munin-node on
# chkconfig --list munin-node
munin-node      0:off   1:off   2:on    3:on    4:on    5:on    6:off

Start munin-node:

/etc/init.d/munin-node start
