What can I find “Agent Availability Management Status” data set in APM cloud?

I am able to find “Agent Availability Management Status data set” in latest Linux OS agent document from https://developer.ibm.com/apm/docs/agent-metricsreference-doc/; However, I am not able to find it in APM. Can anyone show me the path.

I checked in APM Cloud > All My Application > My Components > Components > Linus OS > Attributes Details, I could not find any relates to “Agent Availability Management Status”.
