AI-generated overview

Guide to service mesh observability covering tracing, metrics, logs, golden signals and SLOs for Istio and Linkerd.

What it does: This skill provides instructional guidance on implementing observability for service meshes such as Istio and Linkerd. It explains the three pillars of observability (metrics, traces, logs), the golden signals for mesh traffic, and best practices for sampling, trace context propagation, alerting and retention. It points to a reference file for full templates and worked examples.
When to use it: Use it when setting up distributed tracing or mesh metrics and dashboards, debugging latency or error issues in service communication, defining SLOs, visualizing service dependencies, or troubleshooting mesh connectivity.
Requirements: No scripts are included; it is instructions only. It references a companion file, references/details.md, for templates and worked examples. No specific tools, packages, credentials or network access are stated.

Best Practices

Do's

Sample appropriately - 100% in dev, 1-10% in prod
Use trace context - Propagate headers consistently
Set up alerts - For golden signals
Correlate metrics/traces - Use exemplars
Retain strategically - Hot/cold storage tiers

Don'ts

Don't over-sample - Storage costs add up
Don't ignore cardinality - Limit label values
Don't skip dashboards - Visualize dependencies
Don't forget costs - Monitor observability costs
