Syntropy.Telemetry (syntropy v0.2.0)

Copy Markdown

Custom :telemetry event emitters for the Syntropy runtime.

Event names and measurement shapes live here so instrumentation call sites stay one-liners and SyntropyWeb.Telemetry (the Prometheus reporter) has a single contract to define metrics against.

Events:

  • [:syntropy, :task_run, :stop] — a run reached a terminal state (completed / failed / cancelled). Measurements: duration_ms, agent_count. Metadata: status, strategy, kind.
  • [:syntropy, :llm_request, :stop] — one provider completion call finished. Measurements: duration_ms. Metadata: provider, model, status.
  • [:syntropy, :llm_request, :tokens] — provider-reported usage for a completion (emitted only when the provider returns usage data). Measurements: input_tokens, output_tokens, total_tokens. Metadata: provider, model, stage.
  • [:syntropy, :webhook_delivery, :stop] — one webhook delivery concluded. Measurements: attempts. Metadata: status.
  • [:syntropy, :event_recorder, :flush] — the event recorder flushed a batch to Postgres. Measurements: batch_size, duration_ms.
