KafkaexLagExporter

This project will collect Kafka consumer lag and provide them via Prometheus.

Start

docker run -ti --net="host" -e KAFKA_BROKERS=localhost:9093,localhost:9094,localhost:9095 lechindianer/kafkaex_lag_exporter:0.1

Now you can check the exposed metrics at localhost:4000.

To start the project locally:

KAFKA_BROKERS="localhost:9092" iex -S mix

There is also a docker-compose file included which will start Kafka, serve Kowl (Web UI for Kafka) and start KafkaexLagExporter:

docker-compose up --build

Kowl is served at localhost:8080.

MIX_ENV=test mix test --no-start 

# Don't forget to check credo for code violations:
mix credo
