I wrote a small python script to parse lctl get_param and inject it
straight into our influxdb server - As I was dropping this onto a sonnexion
(as well as our newer systems which had collectd installed) I didn't want
to require any software not already installed on the system.

My plan [one of these days in my spare time] is to wrap it properly as a
collectd python plugin - would people be interested and I'll probably see
if I can find some time to work on it over xmas?

Once it's in influx, we can then just plot it with our normal tooling
(grafana) - some pictures in the pptx at
