I spent an alarming amount of time yesterday attempting to make the most of Apache’s ridiculously easy mod_auth_kerb module for SSO Kerberos authentication with a little in-house Sinatra app I’ve been working on. Apparently Kerberos within nginx or rub…
Earlier this week I wrote about Oldskool which is a Gem extendable search tool. Today I want to show how to create a plugin for it to query some custom source. We’ll build a plugin that shows Puppet Type references, you can see how it will look in the image, click for a larger version. [...]
Back in the day The Well had a text based conference system, you used dial in, then telnet and later ssh to their server and interacted with other members through a text system called PicoSpan. Eventually things moved to the web and it became a lot more forum like. The thing that I really loved [...]
This is a post in a series of about Middleware for Stomp users, please read the preceding parts starting at 1 before continuing below.

Yesterday I gave a quick intro to the basics of Message Orientated Middleware, today we’ll build something kewl and useful. Graphite is a fantastic statistics as a service for your network package. It can store, graph, slice and dice your time series data in ways that was only imaginable in the dark days of just [...]
As most people who follow this blog know I’m quite a fan of messaging based architectures. I am also a big fan of Ruby and I like the simplicity of the Stomp Gem to create messaging applications rather than some of the more complex options like those based on Event Machine (which I am hard [...]
I love graphite, I think it’s amazing, I specifically love that it’s essentially Stats as a Service for your network since you can get hold of the raw data to integrate into other tools. I’ve started pushing more and more things to it on my network like all my Munin data as per my previous [...]
I’ve blogged a lot about a new kind of monitoring but what I didn’t point out is that I do actually like the existing toolset. I quite like Nagios.
