Performance Analyzer provides a powerful REST API for querying Elasticsearch metrics including consumption of network, disk, and operating system resources. This visibility into the metrics gives you the ability to identify system bottlenecks at all layers of the stack.
Performance Analyzer runs independent of your Elasticsearch cluster, ensuring that you can still perform diagnostics and resolve issues, even if your cluster is under duress.
Performance Analyzer supports over 60 metrics across 10 dimensions providing unprecedented instrumentation of your cluster health. You can use a variety of aggregations to measure performance, and capture the details you need to diagnose software bottlenecks and hardware issues.
