performance-investigation Skill
Use for Zava Learning incidents where the platform is reachable but a compute tier is degraded — elevated 5xx from the APIs, slow quiz responses, exceptions, an API with no healthy instances, or a back-office batch job failing on the reporting-worker VM (e.g. nightly grade exports). Diagnoses from Application Insights Published by microsoft in sre-agent.

Skill instructions
Zava Learning — Application Incident Runbook Resource Group: @@RG@@. Services (Container Apps): learner-portal, course-api, assessment-api. Quiz launch path: portal - assessment-api - course-api. Confirm the network/edge is healthy first (App Gateway backend healthy, NSG clean) so you don't misattribute an app fault. Then: 1. Query App Insights failures/exceptions filtered by the failing cloudRoleName. 2. Check Container App revision health and replica counts — an API with zero replicas serves no requests and surfaces as quiz launch / 502 failures with a clean network path. A revision can hit zero replicas two ways: scaled to zero, OR the active revision was deactivated (an inactive revision runs zero replicas). az containerapp revision list shows only ACTIVE revisions, so a deactivated lane looks like it has "no revisions" — list with --all and inspect properties.active / properties.latestRevisionName. The latent cause is often a scale floor of zero in IaC (appLaneMinReplicas: 0); the
