读取应答主控进程的数据库连接池：当前值、最近 1 小时、常驻连接与告警状态
说明（契约原文）
Platform identity with control.upgrades.read or platform.admin (the maintenance page). The figures come from the memory of the control-api process that answers, sampled every 10 seconds: a cycle is bad when in use reaches max_conns - saturation_margin, the average acquire wait exceeds slow_acquire_ms, or an acquire gave up while the pool was full or queued (canceled_acquire, which alerts at once). enter_cycles consecutive bad cycles notify the platform members holding control.upgrades.read or platform.admin (control.db_pool.saturated, also in the administrator message center); recover_cycles consecutive clean cycles send control.db_pool.recovered. An alert entered within dedup_minutes of the last notified one is not sent (notified=false) unless it is still firing once that window has passed. Notifications are written on a connection outside the pool. Only the session check reads the database. Read-only, not audited.
