发布实战:用 v2026.2.17 的 cron stagger 防止整点任务同时打爆资源
场景:多个每小时任务都在整点触发,造成 API 峰值和排队。做法:为 recurring job 显式设置 stagger/--exact,先在单机压测再推广到全量计划。

Prerequisites
- Gateway version upgraded to at least v2026.2.17 and cron jobs are managed via OpenClaw CLI/API.
- You can inspect existing recurring schedules and job runtime logs.
Steps
- Inventory jobs that currently run at top-of-hour and group by API/provider dependency.
- For each recurring job, set deterministic stagger (or use --exact only where strict timing is required).
- Run one cycle in staging and compare queue depth, timeout rate, and model latency vs baseline.
- Promote stagger policy to production and keep per-job telemetry for weekly tuning.
Commands
openclaw cron listopenclaw cron add --helpopenclaw gateway statusVerify
In the next 2-3 hours, recurring jobs no longer cluster at :00 and provider 429/timeout spikes drop measurably.
Caveats
- Do not apply broad stagger to legally/compliance time-locked jobs; use --exact and isolate capacity instead.
- Release note describes capability, but exact CLI flags in your build should be validated with local help(需验证).
