Prometheus is an open-source systems monitoring and alerting toolkit originally built by SoundCloud. It is now maintained by the Cloud Native Computing Foundation (CNCF) and has a vibrant community. Prometheus collects metrics from configured targets, evaluates them using query language, and triggers alerts based on predefined rules.

  • Flexible Query Language (PromQL) 🔍
    Powerful tools for analyzing and visualizing metrics in real-time.
  • Visualization Support 📊
    Integrates with Grafana, Kibana, or Prometheus's own web interface for dashboards.

Use Cases 🧰

  • Server Monitoring 🏗️
    Track CPU, memory, and network usage across hosts.
  • Application Performance Monitoring (APM) ⚙️
    Monitor latency, request rates, and error rates for services.
