SNMP Exporter Configuration Generator
We can generate custom modules that the SNMP Exporter can use.
We do this by generating a customised snmp.yml using a program called the SNMP Exporter Config Generator.
After generating a new snmp.yml, we can configure the existing SNMP Exporter to use the new customised snmp.yml.
The official project can be found at SNMP Exporter Config Generator
Organise a dedicated server for this process so that you don't break your existing Prometheus server or any other production servers.
On the new server, install the dependencies that the SNMP Exporter Config Generator will need.
sudo apt update
sudo apt install unzip build-essential libsnmp-dev p7zip-full
Install the go compiler
apt install golang-go
Test that go is installed.
Download and build the exporter
go get github.com/prometheus/snmp_exporter/generator
CD into the folder where the downloaded repository was saved.
View the contents of the folder
Build the project using go
There should be a new file named generator with execute permissions.
... -rwxr-xr-x 1 root root 7.3M Nov 5 06:53 generator ...
It will download many MIBs files and place them into a folder named mibs
... drwxr-xr-x 3 root root 4.0K Nov 5 07:20 mibs ...
We now need to create a variable that bash can use that points to the new mibs folder
Now we can test that generating a new snmp.yml works.
In the ./generator folder there will be a new file called snmp.yml. We can now replace the existing snmp.yml on the server running SNMP Exporter with this new snmp.yml file if we wanted to.
Ensure that the version of the SNMP Exporter Config Generator matches the version of the SNMP Exporter that you are generating the snmp.yml for. In my SNMP Exporter video, I installed version 0.19 so I need to make sure that the version of the SNMP Exporter Config Generator is from the same repository version.
