Beyla exported metrics

The following table describes the exported metrics in both OpenTelemetry and Prometheus format.

Family	Name (OTEL)	Name (Prometheus)	Type	Unit	Description
Application	`http.client.request.duration`	`http_client_request_duration_seconds`	Histogram	seconds	Duration of HTTP service calls from the client side
Application	`http.client.request.body.size`	`http_client_request_body_size_bytes`	Histogram	bytes	Size of the HTTP request body as sent by the client
Application	`http.server.request.duration`	`http_server_request_duration_seconds`	Histogram	seconds	Duration of HTTP service calls from the server side
Application	`http.server.request.body.size`	`http_server_request_body_size_bytes`	Histogram	bytes	Size of the HTTP request body as received at the server side
Application	`rpc.client.duration`	`rpc_client_duration_seconds`	Histogram	seconds	Duration of GRPC service calls from the client side
Application	`rpc.server.duration`	`rpc_server_duration_seconds`	Histogram	seconds	Duration of RPC service calls from the server side
Application	`sql.client.duration`	`sql_client_duration_seconds`	Histogram	seconds	Duration of SQL client operations (Experimental)
Network	`beyla.network.flow.bytes`	`beyla_network_flow_bytes`	Counter	bytes	Bytes submitted from a source network endpoint to a destination network endpoint

Beyla can also export Span metrics and Service graph metrics, which can be enabled via the features configuration option.

Attributes of Beyla metrics

For the sake of brevity, only the OTEL dot.notation of the metrics and attributes is listed, but the metrics and attributes are exposed underscore_notation when a Prometheus exporter is used.

In order to hide attributes that are shown by default, or show attributes that are hidden by default, check the attributes->select section in the configuration documentation.
