Logstash-exporter

Export metrics from Logstash to Prometheus. The project was created as rewrite of existing awesome application logstash_exporter, which was also written in Go, but it was not maintained for a long time. A lot of code was reused from the original project.

This project is under development and is not ready for use.

Building

Makefile

Available Commands

• make all: Builds binary executables for Linux, macOS, and Windows and saves them in the out directory.
• make run: Runs the Go Exporter application.
• make build-<OS>: Builds a binary executable for the specified OS (<OS> can be linux, darwin, or windows).
• make clean: Deletes all binary executables in the out directory.
• make (default): Runs the Go Exporter application.

File Structure

The main Go Exporter application is located in the cmd/exporter/main.go file. The binary executables are saved in the out directory.

Example Usage

Build binary executables for all supported operating systems:

make all

Run the Go Exporter application:

make run

Build a binary executable for macOS:

make build-darwin

Delete all binary executables:

make clean
