How to retrieve Host Availability metrics via REST API

[AmitChiba]

Hi,

In our environment, we have a requirement to extract the Host last reboot time from AppMon, as well as Dynatrace (Managed). I have been able to do so via a REST API call for AppMon, but Dynatrace Managed appears to be more challenging.

In Managed, I see in the GUI that the Uptime is recorded when looking at the Host details, but this is very vague (e.g. Uptime: over 183 days). My next thought was to consider pulling the availability metrics for a process (*NIX: systemd process, Windows: System process) as this does provide a specific time in the GUI as to when the last downtime occurred (e.g. 5 h 18 min
total downtime Last downtime on 21-02-2018 07:24 - 07:25).

Is there a way that one can retrieve this via a REST API call? Has anyone done this before?

You can pull the host availability metric from the Dynatrace REST API:

com.dynatrace.builtin:host.availability

Here is a good example of a HTML process and host availability report fetched by API that calculates the same numbers as our Web UI shows:

Hello

Please could you help to build something as shown in the git hub (from scratch please)?

I've been looking for this one, but I can't find it in v2. Is this implemented? I really need this information.
