Change 'Value Type' for Sensor from SNMP Library




could you give me a hint how to change Value Type for existing sensor added from SNMP Library template? PRTG shows values as Gauge, I need Delta value.

To solve problem in another way: how to check OID value for sensor added from SNMP Library template? If I knew this then I could add Custom SNMP Sensor.

Dear Razor

The PRTG interface does not show the OID of an SNMP library sensor.

Did you get the OID originally from a MIB file?

Dear Arne,

sure, I am able to get OIDs from original MIB file but this is roundabout way. Don't you think that it should be visible from PRTG? And such basic operation as value type change for graph is fundamental?

Best regards.

Dear razor

The library sensor does not offer changes of the value type once it is created, because changing from gauge to delta or vice versa makes the earlier data unusable. A new sensor should be created in this case. The MIBimporter allows to change the value type so if you import the OIDLib again, you can use a different value type.

To see/edit OIDs, we offer the SNMP Custom sensor. SNMP Library sensors created from an OIDLib are not designed to show the underlining OID, it rather shows the metric in human-readable words taken from the MIB file.
