1 组手动配置 AWS CloudWatch、X-Ray 和 CloudTrail 等服务，需要查阅大量文档，编写复杂的查询语句和告警规则，耗时且容易出错，导致监控系统上线缓慢。
利用此技能，可以快速生成 Log Insights 查询、告警配置和 ADOT 设置，大幅减少手动操作和调试时间，加速可观测性系统的部署和优化，确保关键业务快速获得全面监控。
AWS Observability
Overview
Domain expertise for AWS observability across metrics, logs, and traces. Covers CloudWatch platform capabilities (alarms, dashboards, Log Insights, custom metrics, EMF), X-Ray trace analysis, CloudTrail operational auditing, and ADOT collector configuration.
Works best with the AWS MCP server — enables running CLI commands, querying CloudWatch, and validating configurations directly. All guidance also works with standard AWS CLI access.
Note: Reference files contain specific runtime versions, quota values, and feature matrices that may change. When precision matters (e.g., deploying to production, choosing a runtime, or checking a quota), confirm values against current AWS documentation rather than relying solely on the values in these files.
Routing
| User need | Action |
|---|---|
| Writing Log Insights queries | Read log-insights.md |
| Configuring alarms (metric, composite, anomaly) | Read alarms.md |
| Publishing custom metrics or using EMF | Read metrics.md |
| Setting up X-Ray tracing or ADOT | Read tracing.md |
| Building dashboards | Read dashboards.md |
| Debugging observability issues | Read troubleshooting.md — starts with the 5 most common fixes |
| Debugging canary failures | Read synthetics.md — see Common failures table |
| CloudTrail operational auditing | Read cloudtrail.md |
| Setting up Lambda monitoring with CDK | Use alarm-template.ts as a starting point |
| Creating synthetic canaries | Read synthetics.md |
| Configuring ADOT collector | Use otel-config.yaml as a starting point |
| Spans multiple areas | Read the most specific reference first, then consult others as needed |
