Observability makes a distributed system’s internal behavior visible through telemetry generated from its outputs. In Anthos Service Mesh, sidecar proxies intercept service traffic and send telemetry to Anthos Service Mesh, Google Cloud Monitoring, and Google Cloud Logging without application changes. section 4.5.2 section 15.1.6
A practical observability implementation combines:
- Automatic collection: proxies capture traffic between microservices without requiring developers to instrument application code. section 4.5.2
- Operational signals: integrated metrics, traffic-flow logs, and service telemetry expose service behavior and dependencies. section 4.5.2 section 15.1.6
- Service-level views: dashboards provide tables of deployed services and topology maps connecting workloads, Pods, system services, and owners. section 4.5.2
- Reliability evaluation: SLIs and SLOs connect observed service behavior to customer journeys and SLAs. section 4.5.2 section 15.1.6
Tracing a service dependency
After migrating applications into containers, enable Anthos Service Mesh to map connected services, inspect telemetry, view traffic flows, and identify how a dependency affects an end-to-end customer journey. Use SLOs to judge whether the observed behavior meets the service agreement. section 15.1.6
