WardrikCore.Telemetry (wardrik_core v0.1.0-rc.1)

The events an agent emits.

Each goes to :telemetry and to the agent's WardrikCore.Events sink, as a WardrikCore.Event. Every event's metadata has agent_id. Below, each event lists its other metadata, then its measurements.

Events

• [:wardrik_core, :agent, :start] - state

• [:wardrik_core, :agent, :stop] - reason

• [:wardrik_core, :message, :queued] - message, with its id in its metadata. Measures queued.

• [:wardrik_core, :message, :delta] - span, kind (:content or :thinking), and the streamed text.

• [:wardrik_core, :turn, :start] - kind, span, the message_ids the turn answers, and the metadata given to WardrikCore.resume/3.

• [:wardrik_core, :turn, :stop] - kind, span, outcome, and:

  • messages - the messages an answered turn added.
  • reason - why a turn parked (as WardrikCore.parked/1 returns) or failed.
  • kept and dropped - message counts for an interrupted or timed-out turn.

  Measures duration.

• [:wardrik_core, :turn, :checkpoint] - measures calls.

• [:wardrik_core, :tool_call, :exit] - call, reason.

• [:wardrik_core, :step, :start] - step, span, and model for a :generate step.

• [:wardrik_core, :step, :stop] - step, span, status, attributes, and response or reason. Measures duration and what the step measured.

• [:wardrik_core, :step, :exception] - step, span, kind, reason, stacktrace.

• [:wardrik_core, :subagent, :started] - span, agent, prompt.

• [:wardrik_core, :subagent, :progress] - span, agent, call, tool_calls. Emitted as each tool call begins.

• [:wardrik_core, :subagent, :completed] - span, agent, message, duration_ms, tool_calls, measurements.

• [:wardrik_core, :subagent, :failed] - span, agent, error, duration_ms, tool_calls, measurements.

Spans

A turn's span is the root of its trace. It keeps the same span through a park or a restart. Each step runs in a child span. See WardrikCore.Span.
