I'm trying to use SNMP walk wizard to monitor components such as fans and power supplies. I limited the OIDs with a filter and the job seems to have 261 OIDs found.
But when I click next button no OIDs show up in the tables to select. Does the wizard only handle certain OIDs?

If I don't filter the OIDs at all I get 16249 OIDs and clicking next I get 11 groupings by MIB name covering about 8700 of those OIDs. So it seems to limit what OIDs you can select for monitoring.

Thanks,

Hi Dave (@davemulv1),

Thanks for reaching out. What version of XI are you running?

There have been quite a few changes to the SNMP Walk jobs/wizards and if you are running an older version an upgrade may help.

XI Changelog

I'm running the latest available I believe. 2026R1.2.

Thanks,

Dave

Hi Dave,

Does your XI system have MIBs for these OIDs? The SNMP Walk wizard currently does not display untranslated OIDs. Take a look at the file viewer in the SNMP Walk Jobs table for the job you're seeing zero rows on. If your output only contains untranslated OIDs, that would confirm the issue here. The fix would be to download and load the MIBs for your device on your XI system.

Here's a link to our documentation for uploading MIBs

I've loaded the MIBs and resolved MIB errors in the file viewer and it looks like they're translating.
...but no rows in the select table

Some more information.... I noticed if I click the re-run job control under SNMP Walk Jobs for that job the submit form is corrupted. The device address field has my filter OID instead of the device address, and the filter OID field is empty. Can't just click submit to rerun the job because the authentication is all wrong then.

Both the error you're showing and the corrupted re-run form point to a parsing issue with the SNMP Walk job file you're using. We would probably need to be able to work with the exact file that is having this parsing issue so we can drill down on what the problem is.

Feel free to DM me through this forum with the SNMP Walk job file attached. If you'd rather not do that, I would advise opening a ticket with our support department and providing them the file for a deeper analysis.

Where are the walk jobs actually retained, or would a cut/paste of what shows in the job view suffice ... redacting the creds?

Thanks,

Dave

A cut+paste of the job view should be fine, and yes redacting the creds is also fine. You can find the walk jobs at `/usr/local/nagiosxi/tmp` if you'd rather just drop the full file (redacted, of course).

My guess without seeing the data is that something in the first row, containing the command used to execute the walk, is causing parsing to misbehave.

The log file looks pretty straightforward. attached No OIDs show up in the selection tables.
