A high level view of Nodes/Machines and a way to dive into them and fix issues on individual nodes. See what Operating System version they are on and upgrade those.

Stories

Robert Paulsson is a developer at a small IT company. He's 52 years old. He's a senior engineer, but got tossed the sysadmin hat at the company. They are running several applications in their cluster across 5 nodes. He needs to upgrade the nodes to a newer version of the Operating System running on them.

Sarah Manning Sarah is a part-time backend developer, part-time sysadmin at her company. Her employer runs their web apps on a 8 node cluster. Two of the nodes keeps having problems, but she can't figure out why. She thinks it might be because they are running short on disk space. For now she needs to wall them of so that the apps don't try to run on them while she investigates things.
