Solved: Re: Windows Remote Agent Availability metric

axel_tapia · ‎11 Jan 2023

I've been trying to define an alert based on an agentless host being unavailable, I did this succesfully for Remote Unix plugin/extension, however I don't know which metric from Remote Windows Host Monitoring is equivalent to ext:tech.RemoteAgent.availability (from Remote Unix Extension)

https://www.dynatrace.com/hub/detail/remote-windows-host-monitoring/?query=remote

I don't know if any of the metrics provided with the extension can be used in the same way as ext:tech.RemoteAgent.availability

By querying the metrics com.dynatrace.extension.host-observability* I can get all 55 provided with the extension and none seems to be for Availablity, any idea which metric can be use for this matter?

Hi @axel_tapia,

Unfortunately, the extension does not have the feature to capture the availability metrics and the document which you are referring to will list all the supported metrics which can be fetched by Dynatrace. However, what I can recommend is to create a custom alert at the network level such as "Active TCP Connection" or at the CPU resource level such as "CPU usage". Once the metric is created, you can enable the toggle to trigger an alert for "missing data":

Hope this helps because it would trigger an alert if there is any communication gap or if the remote host is not monitored and the monitoring data is missing.

It seems fundamental that if you are going to monitor a server (Remote in this case) that you want to be able to Alert on it if that server went down. This is a fundamental shortcoming, even if there is a work around.
