I've read many topics with the same problem, but have not found a solution. I'm trying to get SNMP from server on Windows 2012. Mib-file taken from %windir%/system32 and converted using Paessler MIB importer v3.4.6 alpha. Checked by Paessler SNMP Tester 5.0 (Beta 11) - works fine. But when you add the sensor SNMP Library - I get the error "No available interfaces on this device (code: PE049)"

Please run a "Scan OIDLIB" test using our SNMP Tester. Does that yield any results? If so, could you please upload the generated log file, respectively forward us the same to support@paessler.com (please referr to this thread if you forward us the log file by mail)?

Yes, I checked and got good results - https://www.dropbox.com/sh/6j8dhsslbbnziyo/deIJHwDqMF/hostmib.txt . Ok, I send it to your mail.

If you add one of the OIDs that yields a valid result as a SNMP Custom sensor, does this sensor work? What preicse version of PRTG are you currently running?

Yes, if I add one OID from that OIDLIB it work fine. PRTG version 12.2.1. I cannot update right now, because i need reconcile this with the management and security department.

Would you be able to install the latest release (version 13.3.5.2684/2685) as a freeware on a separate machine and check if it works with the same?

I was getting the same error on old PRTG version 7. Seems that MIB importer V3 is too advanced for these versions, and the resulting .oidlib file has to be modified:

  • <oidlist> <system> <version> element has to be "1" instead of "2".
  • the file itself has to be simple ANSI encoding without any BOM marks (importer by default saves in UTF-8 with BOM).

Bonus tip: if you get "not a valid integer" error on sensor value, set its type to "gauge/float". You can modify types in MIB importer. Please note that PRTG v7 did not support string types - sensor will be scanned, but value will be returned only as error.
