2026 OpenClaw Observability & Cross-Border API Troubleshooting:
openclaw logs, Gateway Health & 429/Timeout Backoff

1. Baseline: capture OpenClaw logs with context

Start from the smallest reproducible window—one failing request ID or one bridge session—then widen the tail.

1.1 Follow live logs (TTY)

openclaw logs --follow

1.2 Bounded time window (paste into tickets)

openclaw logs --since "15m ago" --level info

Adjust --since / --level to match your CLI; if your build uses a log file instead, prefer tail -f on that file plus grep -E '429|timeout|ECONNRESET|ETIMEDOUT'.

1.3 Correlate process IDs

pgrep -fl openclaw || true
lsof -nP -iTCP -sTCP:LISTEN | grep -i openclaw || true

Use the PID and listening ports to match log lines to the gateway instance that served the failing call.

2. Gateway health: quick green/red checks

Validate the gateway before blaming upstream models. Replace localhost:PORT with your bind address.

2.1 HTTP health endpoint (if exposed)

curl -sS -o /dev/null -w "http_code=%{http_code} connect=%{time_connect} tls=%{time_appconnect} total=%{time_total}\n" \
  http://127.0.0.1:PORT/health

2.2 TLS / SNI sanity (public hostname)

curl -sS -o /dev/null -w "http_code=%{http_code} total=%{time_total}\n" \
  https://your-gateway.example/health

If TLS handshake time dominates time_total on a cross-border path, tune DNS, MTU, or entry routing before raising API timeouts. Learn more: isolating gateway exposure on Mac cloud nodes.

3. 429 and rate limits: read headers, then backoff

Treat 429 as a control-plane signal, not a random error. Log the response headers your gateway forwards (or strips).

3.1 Capture status + Retry-After

curl -sS -D - -o /dev/null https://api.example/v1/resource \
  -H "Authorization: Bearer $TOKEN"

Look for retry-after (seconds or HTTP-date) and provider-specific headers (x-ratelimit-remaining, etc.). Your client should sleep at least that many seconds before retrying the same key.

3.2 Jittered exponential backoff (shell sketch)

attempt=0
max=6
base=1
hdr=/tmp/oc_hdr.$$
while [ "$attempt" -lt "$max" ]; do
  code=$(curl -sS -D "$hdr" -o /tmp/body -w "%{http_code}" \
    https://api.example/v1/resource -H "Authorization: Bearer $TOKEN")
  if [ "$code" != "429" ]; then break; fi
  ra=$(awk -F': ' 'tolower($1)=="retry-after"{gsub(/\r/,"");print $2;exit}' "$hdr" 2>/dev/null)
  sleep_for=${ra:-$(( base * (2 ** attempt) + RANDOM % 3 ))}
  sleep "$sleep_for"
  attempt=$((attempt + 1))
done
rm -f "$hdr"

If retry-after is an HTTP-date instead of seconds, convert it in your orchestrator; never spin tight loops against 429.

4. Timeouts: separate connect, TLS, and TTFB

On congested cross-border links, a single wall-clock timeout often masks slow connect vs slow first byte.

curl -sS -o /dev/null -w "\
namelookup=%{time_namelookup} connect=%{time_connect} \
appconnect=%{time_appconnect} pretransfer=%{time_pretransfer} \
starttransfer=%{time_starttransfer} total=%{time_total}\n" \
  --connect-timeout 5 --max-time 60 \
  https://api.example/v1/ping

• • High time_namelookup: fix DNS (split horizon, stale TTL, captive resolvers).
• • High time_connect with low TLS: packet loss / middleboxes—try another path or reduce parallel connections.
• • High gap between pretransfer and starttransfer: server or upstream model queueing—increase server timeout only after proving it is not a client pile-up.
