Prometheus provides monitoring capabilities through essential and supplementary components. Below are the key elements:

• Prometheus Server:

  • Periodically collects metrics from specified targets (exporters) via HTTP.
  • Stores these metrics in its built-in time-series database.
  • Evaluates alerting rules to generate notifications based on thresholds.

• Alert Manager:

  • Manages alerts generated by Prometheus.
  • Aggregates, deduplicates, and forwards these alerts to your preferred communication channels.

• Blackbox Exporter:

  • Tests the availability and performance of endpoints using protocols such as HTTP(S), DNS, TCP, and ICMP.

• Node Exporter:

  • Provides hardware and OS-level metrics for Linux servers to Prometheus.

• Grafana:

  • A visualization platform that complements Prometheus, enabling the creation of dynamic, customizable dashboards for detailed data analysis.
