Monitoring the RPi's temp

Following is a simple Munin plugin that will monitor the temperature on your Raspberry Pi. Assumption is that you have Munin installed on the RPi.

#!/bin/sh case $1 in config) cat <<'EOM' graph_title RPi Temperature graph_vlabel temp temp.label C EOM exit 0;; esac echo -n "temp.value " /opt/vc/bin/vcgencmd measure_temp|cut -d'=' -f2|cut -d\' -f1

Save the above as a file called "pitemp". You'll also want to edit /etc/munin/plugin-conf.d/munin-node and add the following entry:

[pitemp] user root

Above will show up in the system's "Other" category. You can alter this by adding a line to the script. See Munin's "How to Write Plugins" page for more detail.
