Peter Steinberger 036e635c71 fix: preserve Gateway error reasons in text logs (#130645)
Print the existing formatted and redacted RPC error instead of a generic reachability claim. Preserve JSON output, selected-target details, fallback/recovery, auth and exit behavior. Verified with real loopback rejection and built CLI before/after proof. Closes #130616.

Logs

openclaw logs

Tail Gateway file logs over RPC. Works in remote mode.

Options

  • --limit <n>: max log lines to return (default 200)
  • --max-bytes <n>: max bytes to read from the log file (default 250000)
  • --follow: follow the log stream
  • --interval <ms>: polling interval while following (default 1000)
  • --json: emit line-delimited JSON events
  • --plain: plain text output without styled formatting
  • --no-color: disable ANSI colors
  • --local-time: render timestamps in your local timezone (default)
  • --utc: render timestamps in UTC

Shared Gateway RPC options

  • --url <url>: Gateway WebSocket URL
  • --port <port>: select a local Gateway port, overriding the configured remote URL and OPENCLAW_GATEWAY_URL; cannot be combined with --url
  • --token <token>: Gateway token
  • --timeout <ms>: timeout in ms (default 30000)
  • --expect-final: wait for a final response when the Gateway call is agent-backed

Passing --url skips auto-applied config credentials; include --token explicitly if the target Gateway requires auth.

Examples

openclaw logs
openclaw logs --follow
openclaw --dev logs --follow
openclaw --profile work logs --follow
openclaw logs --follow --interval 2000
openclaw logs --limit 500 --max-bytes 500000
openclaw logs --json
openclaw logs --plain
openclaw logs --no-color
openclaw logs --utc
openclaw logs --follow --local-time
openclaw logs --port 19083 --json
openclaw logs --url ws://127.0.0.1:18789 --token "$OPENCLAW_GATEWAY_TOKEN"

The selected root profile matches the Gateway's rolling file: the default profile uses openclaw-YYYY-MM-DD.log, while named profiles use openclaw-<profile>-YYYY-MM-DD.log (for example, openclaw-dev-YYYY-MM-DD.log).

Fallback and recovery behavior

  • If the implicit local loopback Gateway asks for pairing, closes during connect, or times out before logs.tail answers, openclaw logs falls back to the configured Gateway file log automatically. Explicit --url targets never use this fallback.
  • --follow does not fall back to that configured file after an implicit local Gateway RPC failure — a stale side-by-side file could mislead a live tail. On Linux it instead uses the active user-systemd Gateway journal by PID when available (prints the selected source); otherwise it keeps retrying the live Gateway.
  • During --follow, transient disconnects (WebSocket close, timeout, connection drop) trigger automatic reconnection with exponential backoff: up to 8 retries, capped at 30s between attempts. A warning prints to stderr on each retry, and a [logs] gateway reconnected notice prints once a poll succeeds. In --json mode both are emitted as {"type":"notice"} records on stderr. Non-recoverable errors (auth failure, bad configuration) still exit immediately.
  • In --follow --json mode, log-source transitions are emitted as {"type":"meta"} records. Track cursors per sourceKind: a stream can move from Gateway file output (sourceKind: "file") to local journal fallback (sourceKind: "journal", localFallback: true, with service.pid/service.unit) and back to Gateway file output after recovery. Do not assume one stable source or cursor for the whole session, and tolerate overlapping lines when recovery replays the Gateway file cursor.

In --json mode, invalid --port, --limit, --interval, or --max-bytes values and conflicting --url/--port options produce the standard CLI failure envelope on stdout: {"ok":false,"error":{"type":"cli_error","message":"..."}}. Terminal log-fetch failures instead emit {"type":"error",...} on stderr. Both exit with status 1.

In text mode, terminal log-fetch failures print the redacted error reason, selected Gateway connection details, and a doctor hint on stderr. A received RPC rejection is shown as the error, rather than reported as a Gateway reachability failure.
