There are some WMI sensors in our deployments (such as Windows CPU Load and WMI Free Disk Space) which at sometimes, have channels added to the sensor. As an example: a 1 CPU core target could suddenly display having 2 CPU cores (one more channel added). Re-adding the sensors could solve the issue but we are not satisfied as the historical data is scattered in different sensors.
Any hints causing such an issue? We are using PRTG Network Monitor 220.127.116.111 x64
