Set up Apache Cassandra monitoring with Grafana Cloud integrations

Estimated time: 1 min

Apache Cassandra integration

Apache Cassandra is an open source NoSQL distributed database designed for high availability and horizontal scalability. The Cassandra integration monitors cluster health, read/write latencies, compaction, and JVM performance.

What it monitorsRead/write latencies, compaction tasks, JVM garbage collection, cluster node status, keyspace metrics
How it worksJMX Exporter exposes Cassandra metrics; Grafana Alloy scrapes them and forwards to Grafana Cloud
What you get8 alerts + 4 dashboards (Overview, Nodes, Keyspaces, Logs)
PrerequisitesJMX Exporter deployed on each Cassandra node

What you’ll see in the dashboards

  • Overview: Cluster-wide node count (up/down), read/write latency trends, pending compaction tasks, and CPU/memory usage
  • Nodes: Per-node performance: latencies, garbage collection, and resource consumption
  • Keyspaces: Pending compactions, repair job tracking, and disk space usage
  • Logs: Cassandra system logs collected alongside the metrics

Key alerts
