PromQL Basic Workshop – Part 1
Welcome to the PromQL Basic Workshop! This guide will help you get started with Prometheus Query Language (PromQL) and understand the monitoring stack defined in your docker-compose-otel.yml.
1. Stack Overview
Your environment is composed of several services, including:
- Prometheus: Scrapes and stores metrics.
- Alertmanager: Handles alerts sent by Prometheus.
- Grafana: Visualizes metrics, logs, and traces.
- Tempo: Stores and queries traces.
- Loki: Stores and queries logs.
- Pyroscope: Handles continuous profiling.
- RabbitMQ: Message queue for microservices.
- Postgres: Database for the API server.
- Beyla: Auto-instrumentation for services.
- k6: Load testing tool.
