Collecting Unifi controller data with collectd

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!

I came across an NPM package that could easily extract data from the Unifi controller software. From there, it was trivially easy to implement a script that harvests data from the controller and passes is along to collectd.

Thus, collectd-unifi was born.

Getting started with it is pretty easy. Just clone the repo, install the NPM dependencies and edit the config file. Once you have the script working, you can use the Exec plugin in collectd to run the script:

LoadPlugin exec
<Plugin "exec">
    Interval 60
    Exec "daemon:daemon" "/usr/bin/nodejs" "/opt/collectd-unifi/unifi.js"

Restart collectd and you should now have Unifi data flowing.

More collectd and pfSense Fun!

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: DHCP Leases CPU Temperature Thermal Zone Temperature SSD Drive Temperature UPS information (via NUT) Here’s the exec script:

Collecting Data From pfSense Using collectd

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!
