This tab just reopened on a browser session restore, I was just wondering if you had any feedback.

The metrics are just pulling from graphite-labs.wikimedia.org using the /render endpoint with the &format=json parameter. They are processed on the development and test servers for the development and testing of Skyline (https://github.com/earthgecko/skyline) and they are used for demo purposes by anomalarm.io

This probably is low proirity and probably nothing, generally steal and irq metric changes tend not to be related to the VM but to an issue on the actual hypervisor host itself.
