We're having a weird issue in our SolarWinds environment that we cannot explain why. We have about 1,800 Windows Servers and they all on SolarWinds agent ver 18.104.22.168. The weird thing is they don't have the same agent plug-ins. About 700 of them have more plug-ins installed than the rest. Below image is an example.
We have tried to reinstall the agent from both manually and from the web console. We also tried to change the agent to a different APE but still does not make any different.
So, what is Cortex Agent Plugin and its related plug-ins?
I got the answer from the tech support. The Cortex plugin is installed automatically when the node has .NET 4.7 installed. This plugin is used for performance analysis on the node.
