Fail2Ban Exporter

This is a Prometheus exporter for Fail2Ban.

It uses fail2ban-client to scrape information and serves it via HTTP on port 9635.

Usage

1. Clone this repo, cd into it
2. Build: $ mvn clean install
3. Configure: $ vi src/main/resources/application.properties
4. Run: $ java -jar target/fail2ban-exporter-<version>-jar-with-dependencies.jar
