+= Kafka Monitoring Stack for Docker Compose (Prometheus / Grafana)
+:toc:
+:toc-placement!:
+
+This repository demonstrates how to use Prometheus and Grafana for monitoring an Apache Kafka cluster.
+
+toc::[]
+
+== Getting Started
+
+=== Start Confluent Platform using Docker
+
+**1. Clone the Kafka Monitoring Suite repository.**
+
+[source,bash]
+----
+$ 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 and Docker Compose.
+
+Note: Depending on your network speed, this may take few minutes to download all images.
+
+[source,bash]
+----
+#  single node Kafka Cluster
+$ docker-compose -f  zk-kafka-single-node-stack.yml
+
+# or 3 nodes Kafka Cluster
+$ docker-compose -f  zk-kafka-multiple-nodes-stack.yml
+
+# single node Kafka Cluster with SASL/PLAINTEXT enable.
+$ docker-compose -f  zk-kafka-single-node-secured-stack.yml
+
+# 3 nodes Kafka Cluster with SASL/PLAINTEXT enable.
+$ docker-compose -f  zk-kafka-multiple-nodes-secured-stack.yml
+----
+
+**3. Create Topic.**
+
+Create `demo-topic` with 6 partitions and 3 replicas.
+
+[source,bash]
+----
+$ ./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.
+
+[source,bash]
+----
+$ ./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.
+
+[source,bash]
+----
+$ ./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](#accessing-grafana-web-ui))
+
+image:./assets/kafka-cluster-healthcheck.png[kafka-cluster-healthcheck]
+
+=== Accessing Grafana Web UI
+
+Grafana is accessible at the address : [http://localhost:3000](http://localhost:3000)
+
+Security are :
+
+* user : `admin`
+* password : `kafka`
+
+=== Accessing Prometheus Web UI
+
+Prometheus is accessible at the address : [http://localhost:9090](http://localhost:9090)
