I upgraded on saturday to 2020.2 from 2018.4 - no issues.
Only I just discovered this:
On a Node Details - Summary pages:
I see
Availability Statistics
Server error: 500-Internal Server Error
The IIS log:
2020-06-16 12:53:52 10.4.0.55 POST /Orion/Services/AsyncResources.asmx/GetAvailabilityStats - 80 USERNAME 10.1.5.3 Mozilla/5.0+(Windows+NT+10.0;+WOW64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/83.0.4103.97+Safari/537.36 http://solarwinds.local/Orion/NetPerfMon/NodeDetails.aspx?NetObject=N:284 500 0 0 1089 - -
Any Idea what this is and how to fix it ?
