Munin-node on PFsense 2.0

hufman

I followed this forum thread and found some tweaks that are needed to make it work.

To do the actual install, I had to do the following:

Then I did the following to set it up:

/usr/local/sbin/munin-node-configure –suggest --shell | sh
sed -i -e 's/MB/KB/' /usr/local/etc/munin/plugins/iostat
mv /usr/local/etc/rc.d/munin-node /usr/local/etc/rc.d/munin-node.sh
Add the following lines to /usr/local/etc/rc.d/munin-node.sh
[ -d /var/run/munin ] || mkdir /var/run/munin
[ -d /etc/rc.conf ] || echo 'munin_node_enable="YES"' >> /etc/rc.conf
/usr/local/etc/rc.d/munin-node.sh start

Then I wanted to get the dhcpd3 plugin working, so I had to do these steps:

setenv PACKAGESITE "ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.1-release/Latest/"
pkg_add -r p5-Net-IP make++ p5-YAML p5-Net-Netmask
ln -s /usr/local/bin/makepp /usr/local/bin/make
/usr/bin/perl -MCPAN -e shell
install HTTP::Date
printf '[dhcpd3]\nuser root\nenv.configfile /var/dhcpd/etc/dhcpd.conf\nenv.leasefile /var/dhcpd/var/db/dhcpd.leases' > /usr/local/etc/munin/plugin-conf.d/dhcpd3.conf
ln -s /usr/local/share/munin/plugins/dhcpd3 /usr/local/etc/munin/plugins/dhcpd3
/usr/local/etc/rc.d/munin-node.sh restart

I've only just started with pfSense, but perhaps this will help other people!

Revised instructions for dhcpd3:

setenv PACKAGESITE "ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.1-release/Latest/"
pkg_add -r p5-Net-IP make++ p5-YAML p5-Net-Netmask

ln -s /usr/local/share/munin/plugins/dhcpd3 /usr/local/etc/munin/plugins/dhcpd3
