# AppSignal Collector

The AppSignal Collector is a program that works with our [OpenTelemetry integration](/opentelemetry) to collect and process your OpenTelemetry data and send it to AppSignal’s servers. It captures error, performance, and metric data from your application, making it easier to monitor and analyze its behavior.

You can install it as a [Linux package](/collector/installation/linux-package) or run it as a container using our [Docker image](/collector/installation/docker-image).

## Features

The collector has the following features:

* Receive OpenTelemetry tracing data.
* Receive OpenTelemetry metrics data.
* Collect host metrics from the host it's running on.
