api.log()

Adds a log entry. Limits:
  • INFO and DEBUG share a budget of 100 emitted entries in Endpoint executions, or 10,000 in Processor and Sandbox executions, including streaming Sandbox.
  • WARN and ERROR each have a separate budget of 100 emitted entries.
  • Error evidence remains in the execution result even after emission is limited: a bounded sample retains the first errors and the most recent one.
  • Sampled-out messages are counted by level. A bounded aggregate appears when sampling starts, on further activity at most once per minute, and on final telemetry when counts changed. Other API methods do not consume this budget.
  • Streaming Sandbox sends entries to its active SSE stream, which also has a backpressure queue limit.
