Prometheus

Real-time metric collection and querying — the de facto standard for modern monitoring.

About Prometheus

Prometheus is the open-source monitoring system that has become the industry standard for collecting infrastructure and application metrics. It works by scraping: at regular intervals, it queries your services (via exporters) and stores the metrics in its local time series database.

Paired with Grafana and Node Exporter on your ServOrbit VPS, you get a complete monitoring stack: real-time system metrics, configurable alerts and performance history. The template deploys Prometheus + Alertmanager + Node Exporter in a single `docker compose up`.

Key features

  • Metric collection via HTTP scraping
  • Expressive PromQL query language
  • Built-in time series database (no external dependency)
  • Alertmanager for alert routing and deduplication
  • Node Exporter for Linux system metrics
  • 400+ available exporters (PostgreSQL, Nginx, Redis…)

When to use this solution?

Infrastructure monitoring

Collect CPU, RAM, disk, network and all the system metrics of your VPS via Node Exporter.

Kubernetes monitoring

The de facto standard for Kubernetes monitoring with kube-state-metrics and Prometheus Operator.

Proactive alerting

Define alert rules (CPU > 80% for 5 min, disk > 90%) and receive notifications via Alertmanager.

Guide

Deploy Prometheus on your VPS

  1. Deploy the stack

    The template deploys Prometheus, Alertmanager and Node Exporter via Docker Compose in a single startup.

  2. Verify collection

    Access Prometheus on port 9090. In Status > Targets, check that Node Exporter is UP.

  3. Write your first queries

    In the Prometheus explorer, test node_cpu_seconds_total or node_memory_MemAvailable_bytes to verify collection.

  4. Connect to Grafana

    Add Prometheus as a data source in Grafana and import the Node Exporter Full dashboard (ID 1860).
