Issue with generator for SNMP exporter

[Denis Trunov]

Hi,

I have as issue with generating snmp.yml file with generator:

MIBbrower from ireasoning.com can see all requester information from loaded MIBs with no problem:

If I try to make very basic generator.yml file

modules:

  snell:

    walk:

      - 1.3.6.1.4.1.6419.1.1.2.10.74 # controllerName

    version: 2

    auth:

      community: public

and try to generate snmp.yml file with generator I get error message that it can not find OID:

./generator --log.level=debug generate

./mibs/vega

level=info ts=2020-05-18T17:40:03.815Z caller=net_snmp.go:142 msg="Loading MIBs" from=./mibs/vega

level=warn ts=2020-05-18T17:40:03.823Z caller=main.go:120 msg="NetSNMP reported parse error(s)" errors=584

level=info ts=2020-05-18T17:40:03.824Z caller=main.go:52 msg="Generating config for module" module=snell

level=error ts=2020-05-18T17:40:03.824Z caller=main.go:130 msg="Error generating config netsnmp" err="cannot find oid '1.3.6.1.4.1.6419.1.1.2.10.74' to walk"

Makefile:5: recipe for target 'generate' failed

make: *** [generate] Error 1

All required files are available for the generator.

The error would indicate otherwise, and that's also quite a few parse errors. Make sure all your MIBs are present in that directory.

You're getting 584 NetSNMP parse errors, there's a generator parse error output option that will probably tell you what's up.

Oh, parse_errors key occurs to be very useful! :)

I get many errors like

{ (is a reserved word): At line 25 in ./mibs/vega/CentraController.mib

2 (is a reserved word): At line 25 in ./mibs/vega/CentraController.mib

Expected "(" (_): At line 91 in ./mibs/vega/CentraController.mib

Seems to be that manufacturer's MIB have a lot of errors. MIBbrowser maybe more errors tolerant. But I even can not imagine what to do with this. :(

Without a copy of the mibs to debug, it's hard to say what's wrong. Are these MIBs available publicly?

I'm not sure. Suppose that they are under NDA. I'm trying to fix'em. Partly successfully. :) Thank you for your hint about parse_errors key. It really helped me.
