Has anybody else seen that Dynatrace started monitoring UNC shares and alerting on it? I looked through release notes and have not found anything (could have missed). Our Product Specialist noticed this also started for another customer he is supporting at same time as it did for me. Started around mid June.
I know how to filter out Unc shares by disk: \\* but just curious why Dynatrace started doing this. This hurting other people?
From DT Chat: now that you have mentioned it, one of my other customers had the same thing happening too.
Based on feedback from our lab, this was the timeline of changes, and indeed some changes would have affected your cluster version:
Before OA 1.267, network drives were not monitored on Windows.
In OA 1.267, Windows network disk monitoring has been introduced. That's why the network share metrics are showing up.
As soon as that version was rolled out to our customers, we discovered that the implementation was causing multiple problems, so we decided to disable it again with a debug flag temporarily.
We made multiple improvements, and the whole feature will be reenabled in OA 1.277.
We hope this helps explain the situation. Going forward, if you do not want to have network drives monitoring, we can disable it by setting a debug flag. Alternatively, you can update OneAgent to a newer 1.267/1.271/1.273/1.275 version that just sets it by default. Please let us know which route you'd prefer to take, and if there are any questions.
