Querying Datadog Graphs from Hubot

As part of my continued mission to add instrumentation and monitoring into basically everything, Datadog is a tool that I've come to really love. In addition to the built-in metrics it can record, such as things like CPU usage, the real power comes in being able to easily define your own metrics and create meaningful visualizations of the true running state of your systems.

Developer On Fire

Obviously we need the server to respond as quickly as possible so being aware of that metric is essential, but on top of that the user also has to wait for…

In under an hour he walks you through building out a real app using tests right from the start, running those tests on both iOS and Android, and also getting into writing UI tests to run locally as well as in Test Cloud. If you're looking…
