Issue
Older versions of .NET, below version 5, required metric collection through WMI calls made by OneAgent extensions.
As of OneAgent version 1.301 the v1 Extension framework that collected these metrics was retired.
Solution
Deploy the extension v2 version of the extension via the Dynatrace Hub within your environment.
Documentation and installation instructions can be found here.
Note
The new extension creates / uses new metric ID's so the data collected by it will be visible under a Custom Device created by the extension, rather than the metrics being placed under the existing .NET process group instances running on your hosts etc. as seen previously.
Alternative Solution
Newer .NET versions, 5+, make alternative data collection routes possible so this extension is not needed with said .NET deployments.
