Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Environment Discovery — Fleet Intelligence

通过 tag 导航发现环境结构,不枚举单个资源。

工作流程

1. 确认扫描目标

  • 确认 account ID(默认 ``,从 environment.md 读取)
  • 确认 region 范围(默认扫描 environment.md 中列出的所有 region)

2. 执行扫描

  • 运行 scripts/discover-account.sh
  • 脚本三阶段独立执行:tag 发现 → 资源聚合 → 告警状态
  • 输出 JSON 到 stdout,同时更新 environments/ 下的 account.yaml 和 account.md

3. 终端摘要输出

  • 解析脚本输出的 JSON,渲染终端摘要
  • 包含:各服务资源数量、当前告警、异常标记
  • 报告中每条结论必须能追溯到本次扫描的 JSON 数据,禁止从 account.yaml 旧注释、历史报告、或记忆中搬运未验证信息

3.1 与上次扫描对比(可选)

  • 读 account.yaml 获取上次 service_catalog,与本次 JSON 做 diff
  • 对比范围仅限于本脚本覆盖的三个 phase(tag / 资源聚合 / 告警)
  • account.yaml 中的注释、log_sources 等不在脚本扫描范围内的信息,不得作为对比结论引用——如需报告这些信息,必须单独查询验证
  • 发现变化时标注「新增 / 消失 / 数量变化」,附具体数据

4. 两种查询模式

模式 1:全局概览("环境怎么样")
  1. 读 environments//account.yaml 获取 service catalog
  2. 查 CloudWatch Alarms in ALARM state → 按 alarm_prefix 归类到服务
  3. 输出:各服务健康摘要 + 异常告警
模式 2:定向下钻("交易引擎的 DB 怎么样")
  1. 从 service catalog 找到 tag 和 resource_types
  2. 用 tag 过滤查询目标资源的 CloudWatch 指标
  • RDS: CPUUtilization, FreeableMemory, ReplicaLag
  • EC2: CPUUtilization, StatusCheckFailed
  • EKS: pod restart count, node status
  1. 只返回指标异常或用户关心的资源详情

查询参考

各服务具体的 AWS CLI 命令和解读要点见 references/service-checklist.md。 不要自行编写查询命令——用 checklist 中验证过的命令。

Automation Boundary

auto-safe

  • 所有 describe / list / get 查询
  • resourcegroupstaggingapi 调用
  • cloudwatch describe-alarms
  • 生成报告文件

human-required

  • 无(本 skill 纯只读)

Gotchas

  • resourcegroupstaggingapi 返回的 ARN 中 ec2 涵盖 instance/vpc/subnet/sg/nat/igw 等所有资源。必须从 ARN 第 6 段提取细分类型(如 ec2:instance),否则会误报"19 台 EC2"实际是网络资源
  • Tag 推断 primary_key 时需排除 k8s 系统 tag(key 含 ./ 的,如 alpha.eksctl.io/xxx
  • 个人/实验账号可能没有业务级 tag(如 service),ProjectName 可能是最接近的替代
  • account.yaml 中的历史注释不是实时数据。脚本只产出 tag/资源聚合/告警三类数据,account.yaml 中的 log_sources、手写注释等是其他流程或人工维护的。巡检报告不得把这些当作本次扫描结论。引用前必须用 CLI 验证当前状态
  • 扫描后清理 account.yaml 中的过期注释。已解决的问题标注解决时间,未验证的问题不要留着——下次扫描会误导
