Hello everyone. A query. One of the recommendations for prtg maintenance is disk defragmentation and monthly restart. What is the recommended process to perform this reset? We have a 5250 sensor prtg cluster. After the restarts, it behaves somewhat unstable, marking the sensors in an unknown state (gray) on many occasions. Also, is it mandatory to perform a cache recalculation each time this reset is performed? Thank you very much for your answers.
