Hello, We have an SQL cluster device added to PRTG, within this device we have added several WMI sensors. In this case we have 6 SQL services that are being monitored via WMI for over a year, about a week ago, 4 of those sensors went into down state and have not been able to come back to up state after they were paused. We have tried pausing and resuming, and also re-adding the sensors, after they are resumed it takes several minutes to read into the error state even when the services are running fine in the actual cluster computer. Also when adding sensors to PRTG, the services show as running but the sensor is always in the Unknown then goes to error after several minutes.
Any ideas or suggestions about this behavior?
