Every host-agent ingest in the service logs ends at ~10 s with no status: the agent gives up at its urlopen timeout (agent.py) before Steward answers. Nothing says which part of ingest is slow, so this measures it: - each phase (parse, metrics with alert evaluation, docker persist, commit) is timed, and a request past 2 s logs one line with the phases, sample count, metric rows, containers and log lines; - a request the server drops when the agent hangs up (CancelledError) logs how long it ran and which phases completed, then re-raises. The fix follows once the logs say which phase it is. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
