snmp generator.yml fails error err="cannot find oid '1.22610.2.4.1.2.2' to walk

[Mehran Saeed]

Hello 

I am trying to generate snmp.yml from generator but it fails. its for a10 load balancers as I needed extra mibs for CPU and memory. below is the generator.yml config. 
I have added the mib file into the correct mib directory as well. 

```

yes sure

below are the logs whilst generating 

```

MIBDIRS='mibs' ./generator --fail-on-parse-errors generate

```

Also if I try generating the if-mib objects from if-mib module they work fine. 

I need to generate mibs for A10. have put the a10 mib file in the mibs directory. 

Looks like its not able to find the OIDs for a10.

Can you post the logs of the `generator generate`? What about `generator parse_errors`?

You probably do not have alle required mibs in the folder.

Please Post the MIBs which you want to use and the generator command you used.

PS:

On top of all MIBs there are comments Like IMPORT which describes which other MIBs are needed.

Fürther use MIBv2 with names instead OIDs. Put the Name in the Generator yml Not the oid.

[Ben Kochie]

I should really make the parse errors warning print in all caps with colors or something. 

Or maybe just fail if there is too many.

Thanks for responding. 

below are the two MIBs for memory I am trying to use:

memory usage: 1.3.6.1.4.1.22610.2.4.1.2.2

Field Name : axSysMemoryUsage 

Field Type: Integer32 

Field Status : current 

Description : The usage memory(KB). 

OID : 1.3.6.1.4.1.22610.2.4.1.2.2  

memory total: 1.3.6.1.4.1.22610.2.4.1.2.1

  Field Name : axSysMemoryTotal 

Field Type: Integer32

Field Status : current 

Description : The total memory(KB). 

OID : 1.3.6.1.4.1.22610.2.4.1.2.1  

I used the cmd below to get the generator executable file:

make generate

then to run the generator ran this cmd:

./generator generate   -m /snmp_exporter/generator/mibs  -g /generator/generator.yml   -o /snmp_exporter/mib/snmp.yml

I tried changing the generator.yml file by mentioning just object id and OID but no luck

Is this MIB in the MIBs folder?

https://www.circitor.fr/Mibs/Mib/A/A10-AX-MIB.mib

[Mehran Saeed]

Yes correct thats the one

Just wondering if this format correct for the generator.yml as in is this how mibs or defined 

auths:
  public_v1:
    version: 1
  public_v2:
    version: 2


  prometheus_v3:
    username: user
    password: pwd
    auth_protocol: SHA
    priv_protocol: AES
    security_level: authPriv
    priv_password: pwd
    version: 3

modules:
  

  a10:
    walk:
      - 1.3.6.1.4.1.22610.2.4.1.2.1

before running the  ./generator generate \ cmd I did make generate as well to create the generator execution file. 

getting the same error no matter what I change. 

[Alexander Wilke]

Try this instead of oid

axSysMemory

axSysCpu

[Mehran Saeed]

yeah tried without oids but still the same result. 

just to double check. 

The correct way is to clone the generator repo, add the custom mib to the mibs dir and run the make generate cmd to generate the executable generator file and then run ./generator generate to run the generator. 

not sure what I am doing wrong here.

Hello Alex 

Thanks for looking into it. I really appreciate that. 

I am able to generate the oids now. I wasn't aware that I need to make sure of this file as well "A10-COMMON-MIB.txt" which is the root file 

Thanks again

FYI, I just checked in a change to the generator that makes missing MIB files a lot more obvious.

https://github.com/prometheus/snmp_exporter/pull/1167

If you pull latest main and build the generator it will try and tell you exactly which MIB modules are missing from the mibs directories.

We're going to cut a new release soon with this functionality as well.
