prometheus-exporter

Set of tools and libraries to help build prometheus exporters of diuerse kind..

In short this is set of functions I borrowed from node_exporter and reworked so a basic API consuming structure can be sneaked into every collector created. At least that was the idea. Also borrowed the config from Victoria Metrics envflag.

How to use

The files in example folder are all that is necessary to build a working exporter.

Main program (example-exporter.go)

This is the where main() lives. Follow the comments in the example-exporter.go to build an exporter. The command-line flags are completely optional, but handy. I borrowed most of these from node_exporter too..

I call it the API (in api/example.go)

This is where the target consumption takes place. The client (APIClient) requires three methods - a login, a get and a logout functions - to authenticate, read and clean any loose ends for every scrape. Follow the comments in file to create your own.

A set of collectors (example has only one in collectors/example.go)

This is a set of metrics collectors sharing a package name. Each collector executes concurrently and must have unique name and needs an update method which will be called by the Collect function. Again, follow the comments to create your own collector.
