What it does
Grafana Beyla is an eBPF application auto-instrumentation tool that observes supported web services and network activity without changes to application code or configuration. It can produce application metrics and traces and run in a container or a Kubernetes deployment. Beyla is useful when teams want basic service telemetry without adding an agent to every application package, but they still need to configure where the data goes and operate the collector in an environment that supports eBPF.
Beyla's setup guide offers several deployment patterns, including a Docker container for an instrumented process and Kubernetes DaemonSet or Helm deployments. A practical trial is to instrument one supported service, choose the deployment mode that matches its host, and verify that the metrics and traces reach the selected observability backend. The official guide describes application auto-instrumentation without modifying application code or configuration; the commands and deployment patterns are documentation examples, not tests performed for this listing.
Beyla uses eBPF to observe application behavior and emit metrics and traces. That makes it a different layer from a browser SDK such as Grafana Faro: Beyla observes services on the host or cluster, while Faro instruments frontend code in the browser. Before rollout, confirm that the runtime environment, permissions, and output pipeline meet Beyla's requirements.
The project is Apache-2.0-licensed. Beyla is an instrumentation component, not a dashboard or a complete alerting product; teams need a compatible destination and still diagnose and fix the issues surfaced by its telemetry.
Strengths
- The docs describe eBPF-based application instrumentation without modifying application code or configuration.
- Multiple deployment methods are documented, including Docker and Kubernetes-based setups.
- Beyla focuses on application metrics and traces rather than only host-level resource counters.
Watch out for
- The host environment must support eBPF, and operators should confirm deployment permissions before rollout.
- The tool emits telemetry but does not itself provide a complete query, alerting, and incident-response workspace.
Best for
- Platform teams that want to instrument supported services without adding language agents to each application.
- Kubernetes or container operators already using an OpenTelemetry-compatible observability pipeline.
- Teams that can verify eBPF support and configure a backend for the emitted metrics and traces.
