It scrapes metrics from configured targets at specified intervals, stores them in a time-series database, and allows powerful querying and alerting. In this tutorial, you&#8217;ll learn the essential steps to set up Prometheus, collect metrics, and create basic alerts.<\/p>\n<h2>Install and Configure Prometheus<\/h2>\n<p>Download the latest Prometheus release from the official site. Extract the archive and run the binary with a configuration file. The default <code>prometheus.yml<\/code> defines scrape targets. Set <code>scrape_interval<\/code> to control how often Prometheus collects data. Start the server, and access the web UI at <code>localhost:9090<\/code> to verify.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/07\/article-1784828086204.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>Use Exporters to Collect Metrics<\/h2>\n<p>Prometheus primarily uses a pull model. To monitor services like databases or hardware, you need exporters. For example, the Node Exporter exposes system-level metrics (CPU, memory, disk). Install and run Node Exporter on target machines, then add its endpoint to your Prometheus configuration under <code>scrape_configs<\/code>. Restart Prometheus.<\/p>\n<h2>Query Metrics with PromQL<\/h2>\n<p>PromQL is the query language for Prometheus. Start with simple queries like <code>node_cpu_seconds_total<\/code> to see raw data. Use aggregations: <code>rate(node_cpu_seconds_total[5m])<\/code> calculates per-second CPU usage rate. Filter with labels, e.g., <code>{mode=\"user\"}<\/code>. The web UI&#8217;s Graph tab helps visualize trends.<\/p>\n<h2>Set Up Alerting Rules<\/h2>\n<p>Define alerting rules in a separate file, e.g., <code>alert.rules.yml<\/code>. Include rules like: <code>- alert: HighCPULoad expr: node_load1 > 0.8 for 5m<\/code>. Reference this file in <code>prometheus.yml<\/code> under <code>rule_files<\/code>. Install Alertmanager to handle notifications (email, Slack). Configure Alertmanager to route alerts to your channels.<\/p>\n<p>Prometheus offers a robust monitoring stack with minimal complexity. Start small by monitoring one server, then scale to multiple services. With PromQL and alerting, you gain deep insights into your infrastructure&#8217;s health.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mastering Server Monitoring: A Practical Guide to Prometheus Setup and Usage Prometheus is a leading open-source monitoring system designed for reliability and scalability.
