WTF is Sensu — A DevOps guide to monitoring
Presented by Toby Jackson, Senior Operations Engineer @ Future
Sensu is a distributed scalable monitoring solution, written in Ruby with a JVM option for Enterprise users. It has multi-master redundancy using a message broker architecture to distribute messages from clients. Clients are configured to either push messages to the master, or provide results in response to requests from the masters.
Broken up into three core sections, this presentation tries to help explain why you monitor software, platforms and your products. What you can look for, and how to best get that information out of your code and finally how Sensu can be used to achieve this in a scalable platform.
