False "Zone Query Overload" alerts from DNS Management Pack 10.1.0.0
The data source that the "Windows DNS Server 2016 and 1709+ Detect Zone Query Overload" monitor and "Windows DNS Server 2016 and 1709+ Number Of Queries Performance Collection Rule" has an issue. If the server is under heavy CPU load at the time the data source runs, it fails and records a value of "0". This causes false alerts, as the "Zone Query Overload" is a "Delta" type monitor, so it sees a huge increase in queries when the next attempt succeeds.
Same here. Frustrating.

Also wanted to mention the same issue occurs with the "Server Query Overload" data source as well.
