Network metrics: new behavior of the direction field
The direction attribute (whose values were ingress/egress until Beyla 1.7.0) has been renamed to iface_direction. This attribute specifies in which direction of the network interface is a flow captured (ingress or egress).
Since Beyla 1.8.0, the direction attribute shows the direction of a connection (valid for TCP): request or response.
PR: #1074
Process CPU metrics: rename attribute process.cpu.state to cpu.mode
Process metrics are still an experimental/unstable OpenTelemetry specification. We renamed that attribute according to the latest changes in the specification.
PR: #1110
Internal metrics: renamed beyla_build_info to beyla_internal_build_info
This breaking change should not have noticeable effect in someone, as internal metrics are aimed to debug Beyla.
