# Observability

This page provides basic information for accessing the observability stack that gets deployed with the Blueprint. The stack includes Grafana, Prometheus, cAdvisor, DCGM Exporter, and Node Exporter.

## Components Overview

| Component     | What it does                                                            |
| ------------- | ----------------------------------------------------------------------- |
| Grafana       | Visualization layer for metrics dashboards and alerts.                  |
| Prometheus    | Metrics collection and time-series storage for scraping exporters.      |
| cAdvisor      | Container-level metrics for CPU, memory, filesystem, and network.       |
| DCGM Exporter | GPU telemetry exporter for temperature, power, clocks, and utilization. |
| Node Exporter | Host-level metrics exporter for CPU, memory, disk, and network.         |

## Service Access Points

| Service       | URL                      |
| ------------- | ------------------------ |
| Grafana       | `http://<HOST_IP>:35000` |
| Prometheus    | `http://<HOST_IP>:9090`  |
| cAdvisor      | `http://<HOST_IP>:18080` |
| DCGM Exporter | `http://<HOST_IP>:9400`  |
| Node Exporter | `http://<HOST_IP>:9100`  |

## Grafana Dashboards

The following dashboards are available by default in Grafana:

Default user and password are:

* user: admin

* password: admin

* **nvidia-dcgm-exporter-dashboard**: GPU metrics such as temperature, power usage, SM clocks, and utilization.

* **Node Exporter**: Host-level metrics for CPU, memory, disk, and network.

* **Docker Monitoring**: Container-level metrics including running containers, total memory usage, CPU usage, and network RX.

## Alerts Microservice Traces

The Alerts Microservice can export OpenTelemetry traces and metrics. This is off by default and uses two additional components, an OpenTelemetry Collector and Jaeger, that are behind the `otel-collector` and `jaeger` Compose profiles. When enabled, the collector receives OTLP on port `4318`, forwards traces to Jaeger and Phoenix, and exposes the OpenTelemetry metrics in Prometheus format on port `8889` (bound to `127.0.0.1` by default).

| Service   | URL                      |
| --------- | ------------------------ |
| Jaeger UI | `http://<HOST_IP>:16686` |

Enablement steps, the span hierarchy, and the configuration reference are in [OpenTelemetry Tracing](/system-components/analytics-microservices/alerts-microservice#opentelemetry-tracing) in the Alerts Microservice page.
