What is Vector?

Vector is a high-performance, end-to-end (agent & aggregator) observability data platform that puts you in control of your observability data. Collect, transform, and route all your logs, metrics, and traces to any vendors you want today and any other vendors you may want tomorrow. Vector enables cost reduction, novel data enrichment, and data security when you need it, not when is most convenient for your vendors. 100% open source and up to 10x faster than every alternative.

To get started, follow our getting started guides or install Vector.

Principles

• Reliable - Built in Rust, Vector's primary design goal is reliability.
• End-to-end - Deploys as an agent or aggregator. Vector is a complete platform.
• Unified - Logs, metrics, and traces (coming soon). One tool for all of your data.

Use cases

• Reduce total observability costs.
• Transition vendors without disrupting workflows.
• Enhance data quality and improve insights.
• Consolidate agents and eliminate agent fatigue.
• Improve overall observability performance and reliability.

Community

• Vector is relied on by startups and enterprises like Atlassian, T-Mobile, Comcast, Zendesk, Discord, Fastly, CVS, Trivago, Tuple, Douban, Visa, Mambu, Blockfi, Claranet, Instacart, Forcepoint, and many more.
• Vector is downloaded over 100,000 times per day.
• Vector's largest user processes over 30TB daily.
• Vector has over 100 contributors and growing.
