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
  1. Inventory jobs that currently run at top-of-hour and group by API/provider dependency.
  2. For each recurring job, set deterministic stagger (or use --exact only where strict timing is required).
  3. Run one cycle in staging and compare queue depth, timeout rate, and model latency vs baseline.
  4. Promote stagger policy to production and keep per-job telemetry for weekly tuning.
Commands
openclaw cron list
openclaw cron add --help
openclaw gateway status
Verify

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).
