panxiao81andClaude Opus 5.5	567b42ed13	修正 monitoring.yml 的 check 模式与 Patroni pending 判断只读探测在 check 模式下照常执行；依赖真实执行结果的等待与验证在 check 模式跳过。 patronictl JSON 会省略空值字段，pending 判断先检查键是否存在。 Co-Authored-By: Claude Opus 5.5 <[email protected]>	2026-10-01 16:20:15 +00:00
panxiao81andClaude Opus 5.5	0cd4a67e12	新增共享 PG 的 SQL 级指标与 dev 告警分流 - 数据库主机上按实例运行 prometheus-community/postgres_exporter 0.20.1，以实例 OS 用户走本地 socket，经 peer + ident 映射到仅有 pg_monitor 的 homelab_monitor 角色；无密码、不经 Bao。版本与官方 sha256sums.txt 同源。 - prod/dev 启用 pg_stat_statements；monitoring.yml 仅在未生效时 reload/重启（prod 走 Patroni pending restart），重复执行 changed=0。 - 告警以上游 postgres_mixin 为底改写为 PrometheusRule，阈值对齐 Patroni failover lag 与 max_slot_wal_keep_size；抓取目标带 env 标签。 - Alertmanager 新增 env="dev" 路由到独立 dev 频道，dev SQL 检查告警补 env。 Co-Authored-By: Claude Opus 5.5 <[email protected]>	2026-10-01 16:20:15 +00:00
