Good and predictable performance is a common expectation across customers of Elasticsearch, an unstructured, distributed database. Elasticsearch, however, is not built with performance diagnosis as a design tenet and this makes it hard for customers to troubleshoot performance problems or provision a cluster. Attend this talk to learn about Performance Analyzer, a feature we built on Open Distro for Elasticsearch, to enable real time performance diagnosis on your Elasticsearch clusters. We will cover the abstractions for observability and root cause analysis, and walk through the design choices we made when building Performance Analyzer on Elasticsearch and the JVM. We will also show a live demo of how Performance Analyzer can help you troubleshoot an issue on your Elasticsearch cluster.
