Description

This dashboard monitors the health and performance of a ZooKeeper deployment by visualizing key operational metrics from Prometheus. It emphasizes critical lifecycle and I/O metrics such as znode_count/ephemerals_count for data store health, global_sessions and local_sessions for client connectivity, and write_per_namespace_sum / read_per_namespace_sum to assess throughput and namespace-level activity. Additional panels cover latency and timing aspects like startup_snap_load_time, startup_txns_loaded, and fsync_time to help pinpoint startup bottlenecks and I/O performance, while error and reliability indicators such as unrecoverable_error_count and digest_mismatches_count provide quick health signals.
