# Instrumentation Hub

Instrumentation Hub is an initial setup and configuration tool within Grafana Cloud that supports Kubernetes Linux environments. It discovers your application and infrastructure services, lets you control the data you gather and what you instrument, and shows the status of the instrumentation process.

> Note
> 
> Instrumentation Hub is in [public preview](/docs/release-life-cycle/).

## Set up with Instrumentation Hub

Install the Grafana Alloy collector, choose the application services and Kubernetes Clusters you want to instrument, activate observability products, and manage or remove instrumentation over time.

Refer to [Set up with Instrumentation Hub](inst-hub/).

## Learn how SDK injection works

When you instrument an application service, Instrumentation Hub pairs eBPF instrumentation with OpenTelemetry SDK injection, so you get language level telemetry without changing your code or rebuilding your images. SDK injection restarts the services it instruments.

To learn what changes in your workloads and why they restart, refer to [How SDK injection works](sdk-injection/).
