This repository demonstrates how to use Prometheus and Grafana for monitoring an Apache Kafka cluster.

1. Clone the Kafka Monitoring Suite repository.

git clone https://github.com/streamthoughts/kafka-monitoring-suite-demo-prometheus.git cd kafka-monitoring-suite-demo-prometheus 

2. Start Confluent/Kafka cluster.

Deploy Kafka, Prometheus and Grafana services using Docker. Depending on your network speed, this may take few minutes to download all images.

./monitoring-suite-start

3. Create topic.

Create demo-topic with 6 partitions and 3 replicas.

./bin/kafka-topics --create --partitions 6 --replication-factor 3 --topic demo-topic

4. Produce messages.

Open a new terminal window, generate some message to simulate producer load.

./bin/kafka-producer-perf-test --throughput 500 --num-records 100000000 --topic demo-topic --record-size 100

5. Consume messages.

Open a new terminal window, generate some message to simulate consumer load.

./bin/kafka-producer-perf-test --throughput 500 --num-records 100000000 --topic demo-topic --record-size 100

6. Open Grafana.

Open your favorite web browser and open provided Grafana dashboard : Kafka Cluster / Global Healthcheck

(see Accessing Grafana Web UI)

7. Stop all containers.

Cleanup all containers.

./monitoring-suite-stop

Grafana is accessible at the address : http://localhost:3000

Security are :

• user : admin
• password : kafka

Prometheus is accessible at the address : http://localhost:9090
