This is a post in a series of about Middleware for Stomp users, please read the preceding parts starting at 1 before continuing below. Today changing things around a bit and not so much talking about using Stomp from Ruby but rather how we would monitor ActiveMQ. The ActiveMQ broker has a statistics plugin that [...]
This is an ongoing post in a series of posts about Middlware for Stomp users, please read parts 1, 2 and 3 of this series first before continuing below. Back in Part 2 we wrote a little system to ship metrics from nodes into Graphite via Stomp. This solved the goals of the problem then [...]
Yesterday I showed a detailed example of a Asynchronous system using MOM. Please read part 1 and part 2 of this series first before continuing below. The system shown yesterday was Asynchronous since there is no coupling, no conversation or time constraints. The Producer does not know or care what happens to the messages once [...]
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 [...]
Some time ago I wrote a little STOMP client – you couldn’t do a whole lot with it since it just sent and printed what it received. I always wanted something better that I can code on the fly and have since learned how to code custom IRBs. So today I wrote a custom IRB, [...]
Basing more and more stuff on mcollective means relying more and more on one of its underlying components : the activeMQ middleware, and more precisely the stomp connector. I hit a weird bug a few days ago and realized that I was not functionnaly monitoring this part of the system. The port was bound and [...]
