mibs work perfectly fine if I use snmpwalk... soon as I try to build it cant find that module? fortigate_snmp does not exist... this came from logicmonitor.

It will be helpful to solve the problem if you upload the yml file as well. I am new to this stuff myself but the error seems to suggest that it is taking "fortigate-fortinet-mib" as a keyword. Have you added "modules: " in the begining of your generator.yml file?

exactly the same as the one found here - https://grafana.com/grafana/dashboards/7567

Can you run "cat generator.yml" and paste the *exact* output here, without mangling the formatting? (Preferably, after pasting, select the text and change font to "Courier New").

The error message appears to be saying that the string "fortigate-fortinet-mib" appears in your YAML file.  But that string does not occur in the sample file that you linked to.

The overall structure of generator.yaml should be like this one: https://github.com/prometheus/snmp_exporter/blob/master/generator/generator.yml

What your asking is near impossible on this webpage, the formatting is awful. But here goes:

modules:
fortigate_snmp:
walk:
    - ifXTable
    - fgVpn        
    - fgSystem        
    - fgIntf
    - fgInetProto
version: 3
max_repetitions: 25
timeout: 10s
auth:
    username: snpuser  # Required, no default. -u option to NetSNMP.                                                                                                                                        
    security_level: noauthNoPriv  # Defaults to noAuthNoPriv. -l option to NetSNMP.                                                                                                                                  
                                # Can be noAuthNoPriv, authNoPriv or authPriv.                                                                                                                                  
    #password: your_password  # Has no default. Also known as authKey, -A option to NetSNMP.                                                                                                                            
                # Required if security_level is authNoPriv or authPriv.                                                                                                                                        
    #auth_protocol: SHA  # MD5 or SHA, defaults to SHA. -a option to NetSNMP.                                                                                                                                      
                      # Used if security_level is authNoPriv or authPriv.

There is no fortigate_snmp in any fortigate MIBs that I can find?

I have run this through a yaml formatting test with no issues. i'm not getting yaml formatting errors.

What im pretty sure that is a custom mib/module and written by someone else that's why it wont work. How it gets posted on grafana is incredible.

If it's exactly the same as  the one in https://grafana.com/grafana/dashboards/7567, then it won't work because that's not the complete file. Also that doesn't have "fortigate-fortinet-mib" in it.
If you have added "modules:", before it then there may be some indenting issue. But I think without the generator.yml file it will be very difficult to guess the issue.

Check the indentation of "modules:", " fortigate_snmp:" and "walk:" try the following,

modules:
  fortigate_snmp:
    walk:
      - ifXTable
      - fgSystem
      - fgVpn
      - fgIntf
      - fgInetProto

    version: 3
    max_repetitions: 25
    timeout: 10s
    auth:
.
.
.

This worked for me. I am using the exact dashboard you mentioned.

I downloaded these three mibs FORTINET-CORE-MIB.txt, FORTINET-FORTIGATE-MIB.txt and FORTINET-FORTIMANAGER-MIB.txt.

You need to indent "fortigate_snmp" under "modules", and "walk" and the other keys under "fortigate_snmp".  Like the following (aside: I don't have any problem with formatting in the Google Groups web interface, but I'm using the "classic" view)

modules:
  fortigate_snmp:
    walk:
      - ifXTable
      - fgVpn        
      - fgSystem        
      - fgIntf
      - fgInetProto
    version: 3
    max_repetitions: 25
    timeout: 10s
    auth:
      username: snmpuser
      security_level: noauthNoPriv
      password: your_password                                                                                                                                              




There is no fortigate_snmp in any fortigate MIBs that I can find?


That's correct.  This is a label which prometheus' snmp_exporter gives to the MIB (or collection of MIBs).  You can choose whatever label you like, but you need to give the same label when scraping, e.g. target=X.X.X.X&mib=fortigate_snmp

Holy moley it worked. Thank you so much everyone.

Sorry off topic but,  Could anyone recommend a text editor for writing yaml that will help me to not run into these formatting issues?

That's because

modules:
fortigate_snmp:
walk:
   ...

is syntactically valid yaml: it's an object with three keys. But it's not semantically valid to the generator, which doesn't expect to see top-level keys "fortigate_snmp" or "walk".

If you think of it as JSON, it's like the difference between

{
  "modules":null,
  "fortigate_snmp":null,
  "walk": {...}
}

and

{
  "modules": {
    "fortigate_snmp": {
      "walk: {...}
    }
  }
}

The first is not understood by the generator, the second is.

So the snmp exporter seems to work but doesnt want to communicate wit the fortigate. I get "server returned HTTP status 400 Bad Request."

But if I use the SNMP exporter page on port 9116 then enter the IP and module it works just fine and can see the OIDs respond with data.

Any ideas?

One url has a typo, "modules" is incorrect. It is "module", not plural.
