Prometheus is a powerful open-source monitoring and alerting toolkit that is widely used in the industry. It provides a flexible and efficient way to monitor your systems and applications. In this section, we will introduce you to the basic concepts and usage of Prometheus.

Basic Concepts

  • Data Model: Prometheus stores time-series data in a high-performance, high-availability storage system. Each data point consists of a metric name, a set of labels, and a value.
  • Scrape: Prometheus periodically fetches metrics from the configured targets using HTTP requests.
  • Alerting: Prometheus can trigger alerts based on rules defined in configuration files. Alerts can be sent to various notification channels, such as email, Slack, or PagerDuty.

Getting Started

To get started with Prometheus, you can follow these steps:

  1. Install Prometheus: Download and install Prometheus.
  2. Configure Targets: Define the targets you want to monitor in the prometheus.yml configuration file.
  3. Set Up Alerting: Create alerting rules in the alerting.yml configuration file.
  4. Start Prometheus: Run the Prometheus server using the command prometheus.
