%description
Grafana Alloy is an open source OpenTelemetry Collector distribution with
built-in Prometheus pipelines and support for metrics, logs, traces, and
profiles.

What can Alloy do?
* Programmable pipelines: Use a rich expression-based syntax for configuring
  powerful observability pipelines.
* OpenTelemetry Collector Distribution: Alloy is a distribution of
  OpenTelemetry Collector and supports dozens of its components, alongside new
  components that make use of Alloy's programmable pipelines.
* Big tent: Alloy embraces Grafana's "big tent" philosophy, where Alloy can be
  used with other vendors or open source databases. It has components to
  perfectly integrate with multiple telemetry ecosystems:
  - OpenTelemetry Collector
  - Prometheus
  - Grafana Loki
  - Grafana Pyroscope
* Kubernetes-native: Use components to interact with native and custom
  Kubernetes resources; no need to learn how to use a separate Kubernetes
  operator.
* Shareable pipelines: Use modules to share your pipelines with the world.
* Automatic workload distribution: Configure Alloy instances to form a cluster
  for automatic workload distribution.
* Centralized configuration support: Alloy supports retrieving its
  configuration from a server for centralized configuration management.
* Debugging utilities: Use the built-in UI for visualizing and debugging
  pipelines.
