Display "Last Message" not "Last Result" in a custom SNMP monitor

We are testing out PRTG to see if it will meet our company's needs. I have created a custom SMNP oid monitor. The device responds correctly and PRTG sees the proper result, but instead of graphing this number, which shows up in PRTG as Last Message, it is showing as the information from a Last Result response. So instead of seeing 8800 - 8900 on the graph I am seeing things like 4ms or 5ms.

Is it possible to graph the message information? That's the right response for the channel, I am not even sure what the 4ms and other small time figure number is coming from.

Seeing from your screenshot, you are indeed using a "SNMP Custom String Sensor", which is not able to graph its results (as they are supposed to be strings). Please try the 'normal' "SNMP Custom Sensor".

hallo,

what are you monitoring? Is that a string or an integer you get in return?

I am sorry but how can I tell?

I believe it is an integer as the response is a number. PRTG is getting two numbers as a response, one is the millisecond figure, the second is the one I want "8800" as an example of what it is right now.

Here is the screen shot of the config.

PRTG is graphing the Response Time but the Last Message field is the one that should be used.

Hey hadiantoso,

Thank you for your KB posting. Actually, there is no way to change/transform the Custom String sensor to the Custom sensor as these two sensors are completely independent from each other.

Therefore you need to deploy a new SNMP Custom Sensor to your device and pause/delete/remain the existing SNMP Custom String Sensor.

Best regards,
Sven
