## Introduction

The OpenTelemetry Collector offers a vendor-agnostic implementation of how to
receive, process and export telemetry data. It removes the need to run, operate,
and maintain multiple agents/collectors. This works with improved scalability
and supports open source observability data formats (e.g. Jaeger, Prometheus,
Fluent Bit, etc.) sending to one or more open source or commercial backends. The
local Collector agent is the default location to which instrumentation libraries
export their telemetry data.

## Objectives

- _Usability_: Reasonable default configuration, supports popular protocols,
  runs and collects out of the box.
- _Performance_: Highly stable and performant under varying loads and
  configurations.
- _Observability_: An exemplar of an observable service.
- _Extensibility_: Customizable without touching the core code.
- _Unification_: Single codebase, deployable as an agent or collector with
  support for traces, metrics, and logs.

## When to use a collector

For most language specific instrumentation libraries you have exporters for
popular backends and OTLP. You might wonder,

For trying out and getting started with OpenTelemetry, sending your data
directly to a backend is a great way to get value quickly. Also, in a
development or small-scale environment you can get decent results without a
collector.

However, in general we recommend using a collector alongside your service, since
it allows your service to offload data quickly and the collector can take care
of additional handling like retries, batching, encryption or even sensitive data
filtering.

It is also easier to [setup a collector](quick-start) than you might think: the
default OTLP exporters in each language assume a local collector endpoint, so if
you launch a collector it will automatically start receiving telemetry.

## Status and releases

The **collector** status is: [mixed][], since core collector components
currently have mixed [stability levels][].

**Collector components** differ in their maturity levels. Each component has its
stability documented in its `README.md`. You can find a list of all available
collector components in the [registry][].
