Description

Stream logs from the Reactor log gateway. The positional <id> is auto-detected: a UUID is treated as a session_id; anything else is treated as a machine_id (a model instance’s name).
By default the command prints the historical window (last few minutes) and then exits. Pass -f / --follow to keep tailing live until Ctrl+C. Combine with shell tools for filtering and slicing:
When stdout is a terminal, structured runtime log lines (JSON) render as a readable single-line format: date and time, LEVEL, message, then the remaining fields as key=value pairs (a record’s exc_info traceback, when present, prints on the lines below). Other lines print verbatim. Piped or redirected output is always the raw line as received (so the examples above and | jq pipelines keep working); pass --raw to force that in a terminal too. Colours honour the NO_COLOR convention. Use --since / --until to request a specific historical window instead of the gateway’s default lookback. Each accepts an RFC3339 timestamp or a duration meaning “that long ago”:
