Free Prometheus Fundamentals Course

FAQs

• Is this course free?

  Yes, this course is free and you will recieve a certification upon completing the course.

• Is this course suitable for beginners?

  Yes, this course is great for beginners in DevOps monitoring. You don't need any experience with Prometheus or other monitoring tools. Each topic is explained clearly and builds on what you learned before, so it's easy to follow.

• What topics are covered in this course?

  You'll learn about monitoring and logging basics, continuous monitoring, how Prometheus works, how to set it up, use metrics and exporters, write PromQL queries, and do hands-on demos with Node Exporter, Apache server monitoring, and running Prometheus with Docker.

• What is Prometheus and why is it used in DevOps?

  Prometheus is an open-source tool for monitoring and alerts. It's popular in DevOps and cloud-native setups because it collects metrics by scraping HTTP endpoints, stores them efficiently, and lets you query them flexibly with PromQL.

• What is PromQL?

  PromQL (Prometheus Query Language) is used to select, filter, and group the time-series data in Prometheus. You can write simple queries to look up metrics or more complex ones for things like finding anomalies or analyzing performance.

• What are exporters in Prometheus?

  Exporters are tools or libraries that turn data from other systems, like Linux servers, web servers, or databases, into a format Prometheus can use. For example, Node Exporter collects system metrics and Apache Exporter collects web server metrics.

• Does this course include hands-on demos?

  Yes, you'll get to do several hands-on demos, including setting up Zabbix monitoring, configuring Prometheus scraping and visualization, using Node Exporter, and practicing PromQL queries from basic to advanced.

• What are the end-of-lesson projects in this course?

  You'll complete two projects: running Prometheus as a Docker container for monitoring at the end of Lesson 02, and a two-part project on monitoring Apache server metrics with Prometheus at the end of Lesson 03.

• How does Prometheus compare to Zabbix?

  Both Prometheus and Zabbix are popular monitoring tools. Prometheus uses a pull-based approach and is built for cloud-native environments, while Zabbix is agent-based and works well with traditional setups. You'll learn more about their differences in a dedicated lesson.

• What is the Prometheus architecture?

  Prometheus works by pulling metrics from targets at set times. Its main parts are the Prometheus server, a time-series database, Alertmanager, Pushgateway, exporters, and a web interface. The course explains how each part fits together.

• What is relabeling in Prometheus?

  Relabeling in Prometheus lets you change or filter metric labels while scraping data. This helps you decide which targets to monitor, how to label metrics, and how to organize data in the database.

• Does this course explain how to run Prometheus with Docker?

  Yes, in Lesson 02 you'll follow step-by-step instructions to run Prometheus as a Docker container and use it to monitor a simple environment. This gives you real practice with container-based monitoring.

• How long will it take to complete this course?

   Altogether, the course is around 3 hours and 42 minutes, and you can go at your own pace.

• Is a certificate provided after completing this course?

  Yes, when you finish the course, you'll get a free professional certificate.

• Can I add this certificate to my LinkedIn profile?

  Yes, once you get your certificate, you can add it to the Licenses and Certifications section of your LinkedIn profile to highlight your monitoring and Prometheus skills to recruiters and employers.
