Michael Viamari created KAFKA-9675: -------------------------------------- Summary: RocksDB metrics reported always at zero Key: KAFKA-9675 URL: https://issues.apache.org/jira/browse/KAFKA-9675 Project: Kafka Issue Type: Improvement Affects Versions: 2.4.0 Reporter: Michael Viamari
The rocksdb metrics listed under {{stream-state-metrics}} are reported as zero for all metrics and all rocksdb instances. The metrics are present in JMX, but are always zero. The streams state is configured with {{MetricsRecordingLevel}} at {{debug}}. I am able to see metrics with appropriate values in the {{stream-rocksdb-window-state-metrics}}, {{stream-record-cache-metrics}}, {{stream-task-metrics}}, and {{stream-processor-node-metrics}}. Additionally, my DEBUG logs show the appropriate messages for recording events, i.e. {{org.apache.kafka.streams.state.internals.metrics.RocksDBMetricsRecorder [RocksDB Metrics Recorder for agg-store] Recording metrics for store agg-store}} It happens that all of my rocksdb instances are windowed stores, not key value stores, so I haven't been able to check if this issue is unique to windowed stores. -- This message was sent by Atlassian Jira (v8.3.4#803005)
