Observability

The observability package provides metrics, logs, and traces for all services running in UIS. All components are designed to work together as an integrated stack.

Services

Service	Description	Deploy
Prometheus	Metrics collection and storage	./uis deploy prometheus
Loki	Log aggregation with label-based indexing	./uis deploy loki
Tempo	Distributed tracing backend	./uis deploy tempo
OTLP Collector	Telemetry pipeline routing to all backends	./uis deploy otel-collector
Grafana	Visualization dashboards for all data	./uis deploy grafana

Quick Start

Deploy the full observability stack in order:

./uis stack install observability

Or deploy individually:

./uis deploy prometheus
./uis deploy loki
./uis deploy tempo
./uis deploy otel-collector
./uis deploy grafana

How It Works

Applications → OTLP Collector → Prometheus (metrics)
                               → Loki (logs)
                               → Tempo (traces)
                                      ↓
                                   Grafana (visualization)

1. Applications send telemetry via OTLP protocol to the collector
2. The collector routes data to the appropriate backend
3. Grafana queries all three backends for unified visualization
4. Pre-built dashboards show service health and telemetry pipeline status

All services deploy to the monitoring namespace.
