How to Use OpenClaw Gateway Health Checks

Good health checks save hours because they replace guessing with a snapshot. The official docs on gateway health are refreshingly practical: start with status and health, inspect linked auth age and session-store state, and only then escalate to logs or relinking. That is the right order because it separates transport, credential, and session problems before they blur together.

When this is the right move

Use gateway health checks whenever a channel stops replying, reconnect behavior looks odd, or you are debugging a remote deployment and want to know whether the gateway is actually healthy before you change anything. They are also valuable as a routine smoke test after upgrades or channel re-auth flows.

The practical workflow

1. Run the lightweight status commands first so you can see gateway reachability, recent activity, and linked auth age without diving into raw logs.
2. Use the deeper probe modes when you need per-account channel checks or a fresh live snapshot from the running gateway.
3. If a channel still looks wrong, inspect logs, credential timestamps, and the session store path before you relink anything.
4. Tune the health monitor intervals and restart caps only after you understand the current failure pattern.
5. Use diagnostics export when you are preparing a shareable bug report rather than copying random log chunks by hand.

Grounded command or config pattern

The gateway health docs center the CLI first, which is exactly how I would operate it too.

openclaw status
openclaw status --all
openclaw status --deep
openclaw health
openclaw health --verbose
openclaw health --json

# Standalone message path on supported surfaces
/status

The docs also call out the key health-monitor settings: gateway.channelHealthCheckMinutes, gateway.channelStaleEventThresholdMinutes, gateway.channelMaxRestartsPerHour, and per-channel healthMonitor.enabled overrides.

Operator notes

Health checks surface linked auth age, channel probe summaries, session-store summary, and probe duration. The docs also explain how diagnostics export packages sanitized state, log metadata, and health snapshots for debugging without leaking chat contents or secrets. That is a good reminder that operational visibility should be shareable on purpose, not because you happened to paste a raw log file.

Rollout approach

For gateway health, make the habit part of your normal operator routine instead of waiting for a full outage. A fast status or health --json check after channel auth changes or gateway restarts buys a lot of confidence for almost no effort.

Common mistake

The common mistake is treating the command or config key as the whole feature. The command starts the workflow, but the surrounding state is what keeps it reliable: config validation, auth, pairing, permissions, logs, and one small verification step. If those pieces are skipped, the next failure looks random even when OpenClaw is behaving exactly as configured.

Maintenance rhythm

Once this is working, write down the exact command, config path, or approval decision you used. Future you will not remember the tiny detail that made the setup safe. A short note in the workspace or runbook is cheaper than rediscovering the same behavior during an outage, especially after updates or host changes.

Safety checks

Do not jump straight to logout and relink just because a channel feels stale. The docs give you better signals first. Also be careful with health-monitor restarts. Restarting a channel too aggressively can hide the real failure pattern or create churn that looks like progress but is really just noise.

How to verify it worked

A healthy snapshot should show the gateway reachable, channels either linked or clearly diagnosed, and the session store path and counts making sense for the deployment. If a channel is broken, the health commands should at least narrow the problem to auth, reachability, or stale activity before you touch any deeper config.

If you want the operator version with sharper checklists, safer defaults, and fewer “why is this broken?” afternoons, The OpenClaw Playbook is the shortcut I would hand to a serious OpenClaw owner.
