Elastic Observability review

Elastic Observability ranks eighth: strong APM for teams already on Elasticsearch, but more setup than the managed leaders. The serverless Complete tier charges for data rather than hosts, with ingest as low as $0.09 per GB for logs and traces, retention at $0.019 per GB per month and 50 GB of free egress. It includes curated views for logs, metrics, traces and synthetic tests, service level objectives and machine learning. On the APM side, Elastic Distributions of OpenTelemetry auto-instrument Java, .NET, Python, Node.js, PHP, iOS and Android, head- and tail-based sampling reduce overhead, and machine learning correlates latency and failure patterns with likely causes. A live dependency map and an AI Assistant that draws on runbooks and GitHub issues help during incidents. The data-based model is fair but harder to estimate than a per host price, and synthetic browser tests and the managed LLM cost extra.
