OpenTelemetry Collector on Kubernetes — unified traces, metrics, and logs

---

What This Does

Full observability stack using OpenTelemetry as the collection backbone. Unified pipeline for distributed traces (Jaeger), metrics (Prometheus + Grafana), and structured logs (Loki). Auto-instrumentation for Python, Go, and Java services. Exemplars link live traces directly to Prometheus metrics.

---

Architecture

OTel Collector receives spans/metrics/logs from instrumented apps, fans out to Jaeger (traces), Prometheus remote-write (metrics), and Loki (logs). Grafana is the single pane of glass.

What's Inside

• OTel Collector Helm chart with custom pipelines
• Jaeger all-in-one for trace storage and UI
• Prometheus + Grafana dashboards (latency, error rate, saturation)
• Loki + Promtail for log aggregation
• Auto-instrumentation via OTel Operator for Python/Go/Java
• Exemplars: link Prometheus metrics to live Jaeger traces

Quick Start

# Deploy full stack
helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
helm install otel-collector open-telemetry/opentelemetry-collector -f values.yaml

# Deploy Grafana + Prometheus
helm repo add grafana https://grafana.github.io/helm-charts
helm install grafana grafana/grafana -f grafana-values.yaml
