Custom OID problem (No such name Error # 2)



Recently added device for APC Inrow Air Conditioner When I add a SNMP Custom OID the sensor shows 'No such name (Error #2)'

I have previously added an APC Environment manager devices and sensors, as well as a UPS, just by specifying OID's.

The "No such name" error means that the specified SNMP object was not found. This can have various reasons - changed OID, network connection problems, etc.

As a first step, please use our SNMP Tester to check if you can properly connect to your device. With this tool, check if you can "Read Device Uptime" and if there are any results when you "Scan Available Standard Interfaces".

For more information about SNMP Tester, please see How can I test the functionality of my SNMP device?

In addition, please see the article My SNMP sensors don’t work. What can I do?

I run the test tool and can get the uptime or available standard interfaces, but I still get the same error : "No Such Name (SNMP error # 2).

Do you have other idea.

that means, given the assumption that the SNMP Settings (port, version, community string, potential authentication credentials, etc.) are correctly set, the target device does not have a counter for this OID.

Best Regards.

Actually the MIB needed to be imported for this particular OID, so your diagnosis is incorrect.

Interestingly other APC devices did not need the MIB to be imported, to reference the OID.

I just discovered that the APC OIDs work properly if you add a zero to the end of the OID. For example the InRow RC value "airIRRCUnitStatusAirFlowMetric" has an OID of according to the APC MIB file, but works properly in PRTG if you enter the OID as

Hello, I have a similar problem, I already tried to add a [b].0[/b] to the end of the OID but in my case, doesn't work.

If I try to Walk to those OIDs, I can get a result:

SnmpWalk v1.01 - Copyright (C) 2009 SnmpSoft Company [ More useful network tools on http://www.snmpsoft.com ]

OID=., Type=Integer, Value=17
OID=., Type=Integer, Value=58
OID=., Type=Integer, Value=23

but if I try to create a sensor I got error [b]No Such Name (SNMP error # 2)[/b]
