Service Mesh Observability

Complete guide to observability patterns for Istio, Linkerd, and service mesh deployments.

Do not use this skill when

• The task is unrelated to service mesh observability
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Use this skill when

• Setting up distributed tracing across services
• Implementing service mesh metrics and dashboards
• Debugging latency and error issues
• Defining SLOs for service communication
• Visualizing service dependencies
• Troubleshooting mesh connectivity
