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.
