NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

Trial
Many monitoring tools are built around the concept of the machine or instance. The increasing use of patterns like Phoenix Server and tools like Docker mean this is an increasingly unhelpful way to model infrastructure: Instances are becoming transient while services are the things that persist. Sensu allows an instance to register itself as playing a particular role, and Sensu then monitors it on that basis. Over time, different instances playing that role may come and go. Given these factors and the increasing maturity of the tool, we felt it was time to bring Sensu back on to the radar.

Assess
Many monitoring tools are built around the idea of the machine. We monitor what the machine is doing and which software is running on it. When it comes to cloud based infrastructure, especially patterns like Phoenix and Immutable servers this is a problematic approach. Machines come and go, but what is important is that the services remain working. Sensu allows a machine to register itself as playing a particular role and Sensu then monitors it on that basis. When we are finished with the machine we can simply de-register it.
