# 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 monitors** | Read/write latencies, compaction tasks, JVM garbage collection, cluster node status, keyspace metrics |
| **How it works**     | JMX Exporter exposes Cassandra metrics; Grafana Alloy scrapes them and forwards to Grafana Cloud      |
| **What you get**     | 8 alerts + 4 dashboards (Overview, Nodes, Keyspaces, Logs)                                            |
| **Prerequisites**    | [JMX Exporter](https://github.com/prometheus/jmx_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

| Alert                              | Severity |
|------------------------------------|----------|
| HighReadLatency / HighWriteLatency | Critical |
| BlockedCompactionTasksFound        | Critical |
| HighPendingCompactionTasks         | Warning  |
| UnavailableWriteRequestsFound      | Critical |
| HintsStoredOnNode                  | Warning  |
| HighCpuUsage / HighMemoryUsage     | Critical |
