Exclude specific VMware ESXi host in the problems card.

One of our VMware ESXi hosts is consistently creating a problem card for "low datastore space". I want to exclude this specific ESXi host from creating a problem card because it is part of its operation and is becoming too noisy. Is this possible?

Hi @blade

Is it possible to tag ESXi hosts in any way and then, based on those tags, create a maintenance window or a separate management zone with an alerting profile that would handle this?

Hi,
I don’t think there is a native way to exclude only one specific ESXi host directly in the VMware anomaly detection settings, because that configuration is environment-scoped rather than host-scoped.
The cleanest workaround is to tag that host and create a maintenance window scoped to that tag, using Disable problem detection. That way Dynatrace won’t create problem cards for that host.
If the goal is only to suppress notifications, but not the problem itself, a separate management zone and alerting profile based on tags would also work.
IMO, what @lubrman suggested is a good direction. If you can tag that specific ESXi host, I’d go with tag + maintenance window scoped only to that host, using Disable problem detection.
