[collectd] How can I determine network interface status? (up/down)

[Николай Кучумов]

For anyone who will be searching for this: the exec plugin works.
I'm sure this isn't the most optimal solution, but it's the only one that
works so far.
If you know a more efficient way, send me a note.

LoadPlugin exec

<Plugin exec>
Exec "nobody:nogroup" "/home/kuchumovn/monitoring/tools/interface_state.sh"
"eth0"
</Plugin>


The script itself:

HOSTNAME="${COLLECTD_HOSTNAME:-localhost}"
INTERVAL="${COLLECTD_INTERVAL:-60}"

while sleep "$INTERVAL"; do
VALUE=`cat /sys/class/net/$1/carrier`
echo "PUTVAL \"$HOSTNAME/exec-interface_state/gauge-state\"
interval=$INTERVAL N:$VALUE"
done
