Wanted to write a playbook that catches ONUs whose optical Rx trends down over 7 days (before they fail hard) and files a proactive maintenance ticket. Docs cover the playbook syntax but I'm stuck on how to reference historic telemetry vs current. Anyone got a working example that queries the last N days of a metric?

Historic queries use the `over` clause — e.g. `metric.onu.rx_optical over 7d as avg`. The AI playbook engine walks that back through the telemetry store and delivers a series you can trend on. Full syntax docs are under Playbooks → Historic Series in the reference. Happy to share our exact playbook if useful.
