All guidance also works with standard AWS CLI access.\n\n**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.\n\n## Routing\n\n| User need | Action |\n|-----------|--------|\n| Enabling/onboarding a service to Application Signals (auto-instrumentation) | Read [application-signals-onboarding.md](references/application-signals-onboarding.md) |\n| Propagating ServiceEvents git/deployment metadata through CI/CD | Read [application-signals-cicd-metadata.md](references/application-signals-cicd-metadata.md) |\n| Per-platform/per-language enablement steps | Read the matching `references/appsignals-guides/<platform>-<language>.md` (e.g. [eks-python.md](references/appsignals-guides/eks-python.md)) |\n| Writing Log Insights queries | Read [log-insights.md](references/log-insights.md) |\n| Configuring alarms (metric, composite, anomaly) | Read [alarms.md](references/alarms.md) |\n| Publishing custom metrics or using EMF | Read [metrics.md](references/metrics.md) |\n| Setting up X-Ray tracing or ADOT | Read [tracing.md](references/tracing.md) |\n| Building dashboards | Read [dashboards.md](references/dashboards.md) |\n| Debugging observability issues | Read [troubleshooting.md](references/troubleshooting.md) — starts with the 5 most common fixes |\n| Debugging canary failures | Read [synthetics.md](references/synthetics.md) — see Common failures table |\n| CloudTrail operational auditing | Read [cloudtrail.md](references/cloudtrail.md) |\n| Setting up Lambda monitoring with CDK | Use [alarm-template.ts](assets/alarm-template.ts) as a starting point |\n| Creating synthetic canaries | Read [synthetics.md](references/synthetics.md) |\n| Configuring ADOT collector | Use [otel-config.yaml](assets/otel-config.yaml) as a starting point |\n| Spans multiple areas | Read the most specific reference first, then consult others as needed |\n\n## Files\n\n| File | Content |\n|------|---------|\n| [application-signals-onboarding.md](references/application-signals-onboarding.md) | Enable Application Signals auto-instrumentation: EKS add-on, CloudWatch Agent IAM, OTLP endpoints, ServiceEvents env vars, Dynamic Instrumentation — two-tier scope by platform/language |\n| [application-signals-cicd-metadata.md](references/application-signals-cicd-metadata.md) | ServiceEvents git & deployment metadata propagation through CI/CD (the 5 `OTEL_AWS_SERVICE_EVENTS_*` vars) |\n| `references/appsignals-guides/` (e.g. [eks-python.md](references/appsignals-guides/eks-python.md)) | 16 per-platform × per-language enablement guides (EC2/ECS/EKS/Lambda × Python/Node.js/Java/.NET) |\n| [alarms.md](references/alarms.md) | Metric, composite, anomaly detection alarms — configuration, constraints, recommended defaults |\n| [log-insights.md](references/log-insights.md) | Complete query syntax, commands, functions, known issues, reusable query library |\n| [metrics.md](references/metrics.md) | Custom metrics, EMF spec, metric filters, high-resolution, retention |\n| [tracing.md](references/tracing.md) | X-Ray → ADOT migration, sampling rules, annotations vs metadata, collector config |\n| [dashboards.md](references/dashboards.md) | Widget types, cross-account/region, dynamic labels, sharing |\n| [troubleshooting.md](references/troubleshooting.md) | Error → cause → fix for all observability services |\n| [cloudtrail.md](references/cloudtrail.md) | Operational auditing, event types, S3+Athena queries |\n| [synthetics.md](references/synthetics.md) | Canary runtime/blueprint constraints, VPC networking, common failures |\n| [alarm-template.ts](assets/alarm-template.ts) | Best-practice CDK Lambda monitoring (alarms + dashboard) |\n| [otel-config.yaml](assets/otel-config.yaml) | ADOT collector config for X-Ray traces + CloudWatch EMF metrics |\n"},"changes":[],"summary":"First saved snapshot.
