I have already onboarded couple of servers to Azure Arc, the status of the Arc machine is showing offline( when i ran azcmagent show) it is showing the agent status as Disconnected. How can i bring the status as Online again, when it is offline?
Verify that the Guest Configuration Arc Service (GCArcService) service is running. Also, if you have a monitoring agent extension deployed you can check the logs on the resource blade. The heartbeat table should display activity if the agent(s) are online.
ARC and the monitoring extensions also need cloud connectivity:
