Why log search matters

Logs are the system of record for modern infrastructure and applications—but without fast, flexible search, they’re just noise. With Elastic, search years of log data at scale to find answers in seconds, detect threats, pinpoint root causes, and correlate logs across services, hosts, and clouds.

Powerful log search, out of the box

Built on the Elasticsearch Platform, search across structured, semi‑structured, and unstructured logs in near real time.

  • Search structured and unstructured logs in sub-second time using Elastic’s powerful query language, ES|QL.

  • Ingest logs from applications, infrastructure, Kubernetes, cloud services, and more into a single, centralized log search platform.

  • Built for high‑volume logging

    Ingest and search petabytes per hour and beyond, scaling from gigabytes to massive data volumes without sacrificing performance.

  • Secure by design

    Protect log data with document-level security, role-based access controls, encryption, audit logs, bring-your-own keys (BYOK), SSO, and more.

Log search use cases

Instantly search logs across your entire environment.

  • Application and infrastructure troubleshooting

    Search in logs to quickly identify errors, crashes, and performance bottlenecks.

  • DevOps and SRE

    Use logs with other signals, like metrics and traces, for faster root‑cause analysis.

  • Security and compliance

    Search historical logs using powerful logging search to investigate threats and meet compliance requirements.

  • Cloud and Kubernetes

    Search logs across dynamic, ephemeral environments using scalable log search built for cloud‑native systems.
