Imil wrote as nice 5 minutes collectd + facette setup article using NetBSD. After a quick look in the ports, I saw it was possible to monitor OpenBSD using Collectd and Facette too. Hang tight, it only takes seconds to achieve.
RRDcached is a daemon that caches a bunch of RRD write requests and apply them at once. This enables to speed up RRD files update. When you install Munin on OpenBSD, RRDcached is also installed by default. But there are things to do to actually use it. Here’s how I did it.
It’s been a while since I used Munin monitoring system. I felt like I was going to have a look at the (not so) new 2.0.x branch ; running on my brand new OpenBSD 5.7.

The Freebox Revolution has a nice management GUI which provides metrics about in/out traffic. Unfortunately, it can only be seen from the management pages when you’ve been authenticated.
Here’s a way to script the grab of the traffic pictures to show them in any Web page.
I’m (once again) in an RRDtool coding time and I found this (dead?) blog, full of really nice explanations and examples on how to enlighten your RRDtool graphs. I’m actually using the information to render my Xymon metrics in a better way.
Be sure to read the Circles of Archimedes for pretty stylish graphs!
