OpenObserve
OpenObserve
Open-source unified observability for logs, metrics and traces, with an AI SRE agent that correlates signals and an LLM cost and eval monitor.
Key features
- Unified Telemetry Store: Holds logs, metrics, traces, RUM, session replay and error tracking in a single system instead of separate tools per signal type.
- Columnar Parquet Storage in Rust: Built on the DataFusion engine with no index to build, which underpins the claimed 140x storage and 30x compute reduction versus Elasticsearch.
- Autocorrelation Engine: Continuously pairs signals across frontend, API, application, database, network and infrastructure layers at over a million signals per second.
- AI SRE Agent: Investigates an incident by building a service graph, quantifying SLO and revenue impact, identifying the root cause from trace evidence, and applying a corrective action such as a rollback.
- Proactive Daily Briefing: Reviews every service over a rolling 14-day window and flags the ones degrading, with the deploy or change that coincided with the regression.
- Agentic and LLM Observability: Tracks token spend, per-model usage mix and error rates across models in production, with failed evaluations shown alongside prompt, output and grader score.
- Transparent Usage Pricing: Charges per GB ingested and per GB queried with retention included, rather than tiered seat or host licensing.
- Self-Hosted or Managed Cloud: The same platform can run entirely inside your own infrastructure or as a fully managed service, including BYOB for enterprise deployments.
Best for
- Cutting Observability Spend: Replace an Elastic or Datadog deployment while keeping a year of log retention, using far less storage and compute for the same data.
- Automated Incident Triage: Let the SRE agent correlate an error-rate spike to a specific deploy and propose the rollback before an engineer is paged.
- Monitoring LLM Applications in Production: Track token cost, model mix and evaluation failures across several models serving live traffic.
- Catching Slow Regressions: Surface a service whose p95 latency quietly tripled after an index rebuild, which threshold alerting would miss.
- Full-Stack Root Cause Analysis: Trace a checkout failure from the browser through the API and into the database on one correlated timeline.
- Compliance-Constrained Deployments: Self-host the whole observability stack so telemetry never leaves your own infrastructure.
- SLO Management: Measure which service level objectives an ongoing incident is putting at risk and how much of a user flow is affected.
