When a windows host is suddenly missing from your system, Datadog should alert you to this. Eventually, everything should recover when only rebooting the host.

Motivation

When you're working in a less volatile system environment, where you expect hosts always to run, you should validate whether you notice whenever a host is rebooting.

Structure

Before restarting a host, we verify that the Datadog monitor is in an ok state Afterward, we trigger the shutdown of a host and expect Datadog to alert about the missing host. Eventually, the host should come back and Datadog turn into an OK state again. While experimenting, we create a downtime for the Monitor so that it will not escalate due to the ongoing alert.
