# `openclaw system`
System-level helpers for the Gateway: enqueue system events, control heartbeats,
and view presence.
All `system` subcommands use Gateway RPC and accept the shared client flags:
- `--url <url>`
- `--token <token>`
- `--timeout <ms>`
- `--expect-final`
## Common commands
```bash
openclaw system event --text "Check for urgent follow-ups" --mode now
openclaw system event --text "Check for urgent follow-ups" --url ws://127.0.0.1:18789 --token "$OPENCLAW_GATEWAY_TOKEN"
openclaw system heartbeat enable
openclaw system heartbeat last
openclaw system presence
```
## `system event`
Enqueue a system event on the **main** session. The next heartbeat will inject
it as a `System:` line in the prompt. Use `--mode now` to trigger the heartbeat
immediately; `next-heartbeat` waits for the next scheduled tick.
Flags:
- `--text <text>`: required system event text.
- `--mode <mode>`: `now` or `next-heartbeat` (default).
- `--json`: machine-readable output.
- `--url`, `--token`, `--timeout`, `--expect-final`: shared Gateway RPC flags.
## `system heartbeat last|enable|disable`
Heartbeat controls:
- `last`: show the last heartbeat event.
- `enable`: turn heartbeats back on (use this if they were disabled).
- `disable`: pause heartbeats.
Flags:
- `--json`: machine-readable output.
- `--url`, `--token`, `--timeout`, `--expect-final`: shared Gateway RPC flags.
## `system presence`
List the current system presence entries the Gateway knows about (nodes,
instances, and similar status lines).
Flags:
- `--json`: machine-readable output.
- `--url`, `--token`, `--timeout`, `--expect-final`: shared Gateway RPC flags.
## Notes
- Requires a running Gateway reachable by your current config (local or remote).
- System events are ephemeral and not persisted across restarts.
