-------------------------------------
Status: Patch Available (was: Open)
> Add ZooKeeper Timeline Metrics integration support
> --------------------------------------------------
>
> Key: AMBARI-26595
> URL: https://issues.apache.org/jira/browse/AMBARI-26595
> Project: Ambari
> Issue Type: New Feature
> Components: metrics
> Reporter: Himanshu Maurya
> Assignee: Himanshu Maurya
> Priority: Major
>
> *Summary*
> Add support for collecting and visualizing ZooKeeper metrics in Ambari
> through Timeline Metrics Provider integration with Ambari Metrics Collector.
> *Motivation*
> ZooKeeper is a critical coordination service in Hadoop clusters but currently
> lacks metrics visibility in Ambari. Operators have no insight into ZooKeeper
> cluster health, performance, connection states, or operational metrics
> through Ambari's monitoring infrastructure. This enhancement would enable
> comprehensive ZooKeeper observability integrated with existing Ambari metrics
> systems.
> *Proposed Solution*
> Implement ZooKeeper metrics collection by:
> # Creating a Timeline Metrics Sink in {{ambari-metrics}} that receives
> metrics from ZooKeeper's Timeline Metrics Provider and forwards them to
> Ambari Metrics Collector
> # Updating ZooKeeper service stack definitions to auto-configure Timeline
> Metrics Provider when Ambari Metrics Collector is present
> # Providing Grafana dashboards for visualizing ZooKeeper metrics
> (connections, latency, throughput, JVM, quorum health)
> # Ensuring upgrade compatibility for existing deployments
> *Key Metrics to Expose*
> * Connection metrics (active connections, sessions)
> * Performance metrics (latency, throughput, request queue depth)
> * Data metrics (znode count, watches, data size)
> * Transaction metrics (commit time with percentiles)
> * JVM metrics (heap, GC)
> * Quorum/ensemble health metrics
> *Benefits*
> * Native ZooKeeper monitoring in Ambari
> * Out-of-the-box Grafana dashboards
> * Historical metrics and trending
> * Performance troubleshooting with percentile metrics
> * Capacity planning visibility
> *Dependencies*
> * Requires ZooKeeper with Timeline Metrics Provider support
> * Ambari Metrics Collector must be installed
