Docker Compose with Grafana and Prometheus for monitoring Cassandra

Grafana and Prometheus Monitoring Apache Cassandra

This repo contains everthing needed to lauch docker containers with Prometheus and Grafana to monitor an Apache Cassandra cluster. The new provisioning features of Grafana 5.x are used to configure the datasource and import the dashboards.

Prerequisites

• Docker Compose
• Apache Cassandra 3.x Cluster

Earlier versions will work but certain Grafana dashboard metrics may not load

• JMX Prometheus Exporter setup on the Cassandra cluster nodes

Here's an Ansible role which can install the exporter for you on an RHEL based OS: Cassandra JMX Exporter

• Node Exporter version 0.16.0 running on the Cassandra cluster nodes

Earlier versions will work but several metric names were changed in 0.16 and certain Grafana metrics may not load

Usage

• Clone the repo and change directories into it

git clone https://github.com/soccerties/cassandra-monitoring.git
cd cassandra-monitoring

• Edit the json files prometheus/tg_cassandra.json and prometheus/tg_node.json and define your collection endpoints

    ],
    "labels": {
      "cluster": "test_cluster"
    }
  }
]

• Edit any other parameters you'd like in the docker-compose.yaml file. Such as the Grafana admin password. Then launch the docker containers

docker-compose up -d

That's it! If there were no erros you can open a browser and visit the Grafana interface and login (http://localhost:3000/)
