PRTG, Custom SNMP, Alert Status




I created a custom SNMP sensor to monitor a process on a Linux machine. I have configured the Linux machine's SNMP service to change the SNMP value if the process is not running. I then use the PRTG to monitor this value. By default, when the value is 0 (zero) it means the process is running. When the value changes to 1 it means the service is has stopped.

The PRTG is picking up these value changes without a problem. But what I want to do is be able to change the status of the Senor and put it into Alarm if the value changes to a specific value.

I have looked at the Notifications, and the closest thing I can find is the "Log Event". I don't necessarily want to send out messages, but it would be nice if I can change the status of the sensor so that it shows up under the "Alarms" section of the PRTG Interface.

Is there a way to accomplish this using a custom SNMP?

you can do this using the Error/Warning-Limits on the Channel-Tab of the Sensor. Simply set the Upper Error Limit to 0, then everything above will be considered as error.

best regards.
