What performance optimization and monitoring tools does Storm offer?
Storm offers the following performance tuning and monitoring tools:
- Storm UI provides real-time topology visualization, component statistics, worker node information, and other features for monitoring the operational status of topologies.
- Storm includes the Metrics API, which can be used to gather, display, and analyze metric data for the Storm cluster, helping users monitor the performance of the cluster.
- The Storm-Profiler tool is used to analyze performance bottlenecks in a topology, helping users identify potential performance issues and provide optimization suggestions.
- Storm offers a Resource Aware Scheduler that dynamically schedules based on the resource demands of the topology and the resource status of the cluster to improve the performance and resource utilization of the topology.
- Storm Configurations: Users can optimize topology performance by adjusting Storm configuration parameters, such as changing worker counts, adjusting the parallelism of Spouts/Bolts, and so on.
