Hello,

yesterday we have taken a few host offline and dynatrace managed has opened problems for them (open now for 1day+).

Alert Message: “Host or monitoring unavailable due to connectivity issues or server outage”

How does Dynatrace decide if a Host has been shut down intentionally?

We have tried to turn the monitoring off for those hosts, but the problems stay open. How can we close those problem?

Thanks

Bernhard

Same for me. It seems you need to uninstall it before shutting down to eliminate this alert

Just founded workaround.

Go to host settings → general → anomaly detection → disable all.

Disabling monitoring in Dynatrace UI before taking host down did not help?

Disabling monitoring after VM crashed didn’t helped
