Can't create SNMP Library sensor

Votes:

0

I am trying to add an SNMP Library sensor to an Eaton UPS. I have downloaded the MIB file from Eaton, imported it with the Paessler MIB Importer, and the oidlib file shows up in the snmplibs folder on the server.

When I select SNMP Library as the sensor to add, the Eaton oidlib file that I added shows up in the list. But when I select it, PRTG responds with:

Could not create the sensor SNMP Library on device.... No Access (SNMP error # 6)

What does this mean? I have Googled this with no success.

Thanks, Dave

Hello Dave,

Please use our SNMP Tester, run it on the PRTG Host (or host of the Remote Probe), and perform a "Read Device Uptime" against the target device. Which results do you get in the Tester?

Whoops, please disregard my previous post. The device is actually set to SNMP v1, not v2c. When I run the SNMP Tester using v1, it succeeds:

1/6/2017 12:05:15 PM (14 ms) : Start using SNMP V1 1/6/2017 12:05:15 PM (23 ms) : ------- 1/6/2017 12:05:15 PM (26 ms) : Value: 241481007 1/6/2017 12:05:15 PM (30 ms) : Done

But when I run SNMP Tester on the OIDLIB file, I get an error:

XML Parser mismatch: Wanted <and then a lot of binary gibberish>

The OIDLIB file looks OK to me:

<?xml version="1.0" encoding="UTF-8"?> <oidlist> <system> <version> 2 </version> </system> <list> <entry> <name> EATON-EMP-MIB|xups environment|xups env remote temp </name> <lookupname/> <oid> 1.3.6.1.4.1.534.1.6.5.0 </oid> ...etc.

Hi David,

Please provide the "<and then a lot of binary gibberish>" information as it is quite necessary to troubleshoot this issue. You can paste both the "gibberish" and the OID-Lib on Pastebin if it is too long.

Unfortunately the message is in a Windows dialog box that doesn't let me copy the text, but here's a screenshot of the entire message:

error text

The oidlib file is here on Pastebin: http://pastebin.com/QaWPHfXJ

Dear David,

Please copy the content of the OIDLIB file and paste it in a new and fresh text file. Afterwards change the extension to ".oidlib". Now check if the SNMP Tester is throwing the same error. I assume that this is an encoding issue.

Answer of the customer:

Copying and pasting the file contents into a new OIDLIB file results in: 1/10/2017 4:17:17 PM Start Scan Found OIDs: No OIDs found

That means that the device does not support the OIDs you are trying to query. So basically the MIB you are trying to use against the target device is not supported by the target device. Maybe the vendor of the device can help you further into finding the correct MIB.
