Network metrics (experimental feature)

⚠️ Network metrics is an experimental under development feature, expect breaking changes in the short term.

In addition to application-level metrics, Beyla can provide now the beyla.network.flow.bytes network-level metric, which captures the network bytes between two endpoints in a host.

This feature is independent from the Beyla application observability feature, and is application-agnostic. Beyla will capture all the network metrics in the host, independently of which applications is Beyla instrumenting.

To learn how to activate and configure network metrics, refer to the Grafana Beyla network documentation
