Basically these are alerts coming from YARN and AMS side. So can you please check the NodeManager logs (for Yarn) and similarly AMS collector log to see if it has any Error?

Also please check if the AMS collector and Grafana are running or not ? Checking the AMS collector log and Grafana log will give us more details here.
