Extending my post from last year, here’s some additional data I’m grabbing from pfSense and stuffing into collectd via a script. I’m now grabbing:
Thermal Zone Temperature
SSD Drive Temperature
UPS information (via NUT)
Here’s the exec script:
This combined with the data that collectd can natively collect you can assemble into a pretty neat dashboard using Grafana. Here’s one I’ve been building for the firewall.
Next step will be nagios or some other kind of alerting, especially on temperature. That’s the big thing I really want to monitor with a lot of this stuff, since my networking equipment is in an upstairs closet that does not hae the best ventilation (especially during the summer).
Did something I wrote help you out?

So I’ve recently been on a graphing thing, wanting to collect all kind of data from my home network. And collectd seems to be a good candidate for doing that. With a huge number of plugins, it can collect and send just about anything you can think of to a time series database (I’m using InfluxDB for this). But, there’s a significant hole in my data collection: my pfSense firewall. Well, not anymore!
As you can tell from the last few posts, I’ve been having a lot of fun with collectd and instrumenting my systems. But I had one glaring hole until recently: my Ubiquti Unifi AP access points. Well no longer!
