We have a printer needing a PCU replaced. I was curious as to why the need to replace a PCU wouldn't have thrown some type of an alert in PRTG. No notification was sent because the printer didn't have a sensor that would pick up that issue...obviously! Usually I just do an auto-discovery of sensors, but I decided to manually add the SNMP Printer Sensor to the printer having issues. All channels are showing up/green in that sensor; however, instead of the sensor showing a "Ready" message, it shows "Replace PCU" message. So...my question is, how can I create a notification based on that message? It's not tripping any alerts currently. Looking through the Notification Triggers for that sensor, it doesn't look like I have the ability to create a notification based on message.
