Generate HUAWEI SNMP Exporter Module

Now that we have the SNMP Exporter Configuration Generator setup, we can try and create custom modules to use in the SNMP Exporter.

For this example, I will create a module for a generic HUAWEI device.

I will need to download a HUAWEI MIB and research which OIDs I should walk/get.

First, navigate to the folder where it will be saved. ie, the ./generator/mibs folder

cd ${GOPATH-$HOME/go}/src/github.com/prometheus/snmp_exporter/generator/mibs

Download the HUAWEI MIB

curl http://www.circitor.fr/Mibs/Mib/H/HUAWEI-MIB.mib > HUAWEI-MIB.mib

View the contents of the folder and it should contain the new file HUAWEI-MIB.mib

ls -lh

Now navigate back one folder into the generator folder

cd ..

And we need to edit the generator.yml and add the information for the Huawei device.

sudo nano ./generator.yml

modules
  ...
  hauwei:
    walk:
      - 1.3.6.1.2.1.10
      - 1.3.6.1.2.1.47
    version: 2
    auth:
      community: public
    overrides:
      ifType:
        type: EnumAsInfo
  ...

After saving the file, create the variable that bash can use that points to the new mibs folder

export MIBDIRS=mibs

The run the generator to generate a new snmp.yml.

./generator generate

If all is correct, then there will be a new node in the snmp.yml named huawei containing instructions on which OIDs to walk/get and which metrics will be made available for Prometheus.
