snmp_exporter version: output of snmp_exporter -version

No error in smp_exporter, but in generator. Latest generator commit is a622a79.

What device/snmpwalk OID are you using?

Default IF-MIB interfaces table with ifIndex. Tried with the buildin MIB, and with http://www.net-snmp.org/docs/mibs/IF-MIB.txt

What did you do that produced an error?

generator.yml:

modules:
  # Default IF-MIB interfaces table with ifIndex.
  if_mib:
    walk: [sysUpTime, interfaces, ifXTable]
    lookups:
      - source_indexes: [ifIndex]
        lookup: ifAlias
      - source_indexes: [ifIndex]
        lookup: ifDescr
      - source_indexes: [ifIndex]
        # Use OID to avoid conflict with Netscaler NS-ROOT-MIB.
        lookup: 1.3.6.1.2.1.31.1.1.1.1 # ifName
    overrides:
      ifAlias:
        ignore: true # Lookup metric
      ifDescr:
        ignore: true # Lookup metric
      ifName:
        ignore: true # Lookup metric
      ifType:
        type: EnumAsInfo

(as copied from the example generator.yml)

Run the generator with the following command:

$ docker pull prom/snmp-generator
$ docker run -ti \                                                                                                                                           
-v /data/snmp-exporter/mibs:/root/.snmp/mibs \
-v /data/snmp-exporter/exporter:/opt/ \
snmp-generator generate 

What did you expect to see?

Generator runs and creates snmp_exporter config.

What did you see instead?

INFO[0000] Loading MIBs from mibs                        source="net_snmp.go:141"
WARN[0000] NetSNMP reported 1 parse error(s)             source="main.go:104"
INFO[0000] Generating config for module if_mib           source="main.go:49"

FATA[0000] Cannot find oid 'ifXTable' to walk            source="tree.go:290"

Since i was unsure if the builtin snmp binaries did provide these MIBs, i downloaded them separately from the URL specified above and mounted the host directory containing the MIBs to /root/.snmp/mibs with the same result.

It makes more sense to ask questions like this on the prometheus-users mailing list rather than in a GitHub issue. On the mailing list, more people are available to potentially respond to your question, and the whole community can benefit from the answers provided.

I solved my issue by generating all the OID name aliases from the MIB files instead

see, https://github.com/TheShellLand/docker-smidump/blob/master/mibs/generator.yml

The link no longer exists, and I have exactly the same issue. Could you elaborate in a bit more detail how did you generate the OID aliases from the MIB files?
