Fail to generate snmp.yml from Fortigate Mibs

[Donny Achmadi]

Hi All,

I am facing issue when generating exporter .yml file for Fortigate.

I have followed this dashboard https://grafana.com/grafana/dashboards/7567, but getting error when run ./generator generate

[root@etp-monitor1 generator]# ./generator generate

level=info ts=2020-11-19T02:09:03.037Z caller=net_snmp.go:142 msg="Loading MIBs" from=/home/kadmin/go/src/github.com/prometheus/snmp_exporter/generator/mibs

level=warn ts=2020-11-19T02:09:03.052Z caller=main.go:120 msg="NetSNMP reported parse error(s)" errors=2815

level=info ts=2020-11-19T02:09:03.053Z caller=main.go:52 msg="Generating config for module" module=fortigate_snmp

level=error ts=2020-11-19T02:09:03.053Z caller=main.go:130 msg="Error generating config netsnmp" err="cannot find oid 'fgInetProto' to walk"

This is my generator.yml file:

modules:

  fortigate_snmp:

    walk:

      - ifXTable

      - fgVpn

      - fgSystem

      - fgIntf

      - fgInetProto

    version: 3

    max_repetitions: 25

    timeout: 10s

    auth:

======

When I try to run ./generator parse_errors, I can see a lot of errors as attached.

I downloaded the MIB file from Fortigate WEB console under SNMP.

I need your help to get this working :)

Thanks,

Donny

To fix these, check the oid names being called for example rptrPortEntry (from "level=warn ts=2020-10-05T11:03:02.476Z caller=tree.go:83 msg="Can't find augmenting node" augments=rptrPortEntry node=ciscoRptrPortEntry") in the mib files using notepad++ or some other editor.
 
We find that rptrPortEntry is found in CISCO-REPEATER-MIB.mib, line 28 and is being imported FROM SNMP-REPEATER-MIB. So now we check if the SNMP-REPEATER-MIB exists in the mibs folder. If not, then google this mib, download and store it in the mib folder. Repeat these steps for all the errors.

This example was from the error I had gotten.
