Beyond Production: End-to-End CI/CD Observability With OpenTelemetry
summary
Demonstrates end-to-end CI/CD observability using OpenTelemetry with Argo Workflows, ArgoCD, GitLab and Signos: deploys an OpenTelemetry collector (minikube), scrapes ArgoCD metrics via Prometheus, uses OTel CLI to emit and stitch root + child spans from workflow DAGs, and exports OTLP traces/metrics to Signos. Claims three concrete deliverables—instrument Argo Workflows and ArgoCD, capture CI/CD semantic attributes, and surface build/deploy latency and queue depth—and shows traces and metrics visible in Signos (demo works though some spans show 0.00ms when steps run instantly).
