Overview ¶
Package telemetry is the one place steps meets the OpenTelemetry SDK, off unless OTEL_* asks: the docker and GCE clients already trace against the global provider, so installing one is all their calls need.

Functions ¶
func Enabled ¶
Enabled answers whether the environment asks for a signal, TRACES or METRICS. The exporter would default to localhost:4318 with nothing set, which is a dial on every run nobody asked for, so an exporter or an endpoint has to be named.
func Handler ¶
Handler traces every request a server answers but those to untraced paths, which a platform polls every few seconds. echo stamps the matched route onto the request, which otelhttp reads back to name the span by route rather than by URL.
func LogHandler ¶
LogHandler adds trace_id and span_id to a record logged under a recording span, so a log line can be found from its trace and back.
func ObserveQueue ¶
ObserveQueue reports pending builds per pipeline as steps.queue.pending, asking pending at each export; the returned func stops it, and must run before whatever pending reads from is closed.
func Start ¶
Start returns the flush a command must run before it exits, a no-op when telemetry is off.
func Transport ¶
func Transport(base http.RoundTripper) http.RoundTripper
Transport traces every request a client makes and carries the trace context to the server.
