quiet often we are seeing alerts from Dynatrace as&nbsp; **Host or monitoring unavailable ,** &nbsp; although the host is up and we see Oneagent is running on our servers. Can you advise what is the underlying issue we have here ?

thanks for sharing the docs.

I would like to understand more her, we have Oneagent monitoring on my servers in Full stack mode. recently we have been observing&nbsp;&nbsp; **Host or monitoring unavailable** &nbsp;&nbsp; alerts though i can see my host is available and running

If there is Network connection to the monitored host is lost, how can we identify this, and what fix/solution can be applied to avoid the Network connection loss

I would also like to share the Dynatrace link which can be helpful , appreciate your valuable feedback on this
