This project implements the remote_writer interface for prometheus to capture metrics and serialize each sample as json. It is intended just as an example to show how to do it simple with java, because most examples are developed in golang.
To recompile protobuf files, you may have protoc (protobuf compiler). In linux, you can install protobuf-compiler package to provide it.
The project can be built with
mvn clean install
To test it, run with
mvn compile quarkus:dev
and configure prometheus adding
remote_write:
- url: 'http://<your-endpoint>/write'
