Understanding Cassandra Performance Metrics
Client Requests Rate
Monitors the rate of requests received by Cassandra, helpful in understanding traffic and load patterns.
Client Request Latency Histogram
Tracks read and write latency percentile distributions (p50, p75, p95, etc.), critical for evaluating response times.
Cache Hit Ratios
Measures the effectiveness of Cassandra’s cache mechanisms including row and key cache hit ratios.
JVM Memory and GC Metrics
Monitors JVM memory usage alongside garbage collection metrics for informed memory management.
Here’s a quick table that summarizes key metrics:
| Metric Name | Description | Unit |
|---|---|---|
cassandra.client_requests_rate | Client requests rate | requests/s |
cassandra.client_request_read_latency_histogram | Read request latency percentiles | seconds |
cassandra.row_cache_hit_ratio | Row cache hit ratio | percentage |
cassandra.jvm_memory_used | Amount of JVM memory used | bytes |
cassandra.compaction_completed_tasks_rate | Rate of completed compaction tasks | tasks/s |
