A High-Performance, Logs, Metrics, & Events Router

---

Vector is a high-performance observability data router. It makes collecting, transforming, and sending logs, metrics, and events easy. It decouples data collection & routing from your services, giving you control and data ownership, among many other benefits.

Built in Rust, Vector places high-value on performance, correctness, and operator friendliness. It compiles to a single static binary and is designed to be deployed across your entire infrastructure, serving both as a light-weight agent and a highly efficient service, making the process of getting data from A to B simple and unified.

Features

• Fast - Built in Rust, Vector is fast and memory efficient. No runtime. No garbage collector.
• Correct - Obsessed with getting the details right.
• Vendor Neutral - Does not favor a specific storage. Fair, open, with the user's best interest in mind.
• Agent or Service - One simple tool to get data from A to B. Deploys as an agent or service.
• Logs, Metrics, or Events - Logs, metrics, and events. Collect, unify, and ship all observability data.
• Correlate Logs & Metrics - Derive metrics from logs, add shared context with transforms.
• Clear Guarantees - A guarantee support matrix helps you understand your tradeoffs.
• Easy To Deploy - Cross-compiles to a single static binary with no runtime.
• Hot Reload - Reload configuration on the fly, without skipping a beat.
