Course Introduction
Hello and welcome to this in-depth course on preparing for the Prometheus Certified Associate Exam!
My name is Sanjeev, and I will be your guide on this journey to mastering Prometheus. In this course, we cover everything from the fundamentals to advanced configuration options, ensuring you are fully prepared for the certification exam.
What You'll Learn
In this lesson, you will:
- Understand the basics of Prometheus, including its history, benefits, and architecture.
- Perform practical tasks such as installing a Prometheus server and configuring exporters for effective resource monitoring.
- Explore various configuration options such as authentication, encryption, and service discovery.
- Master PromQL, Prometheus’s powerful query language, to retrieve and analyze data.
- Learn how to integrate Prometheus into a Kubernetes environment for robust cluster monitoring.
- Practice with hands-on labs that provide immediate feedback and reinforce your learning.
- Prepare with a final mock exam mirroring the structure and difficulty of the actual certification test.
Hands-On Learning
Each video lecture is paired with interactive labs to solidify your understanding. By engaging in these exercises, you receive instant feedback and practical experience.
Practical Examples
Below is an example of extracting the Prometheus package:
root@prometheus-server ~ # tar xvf prometheus-2.40.1.linux-amd64/
prometheus-2.40.1.linux-amd64/NOTICE
prometheus-2.40.1.linux-amd64/prometheus
prometheus-2.40.1.linux-amd64/LICENSE
prometheus-2.40.1.linux-amd64/console/
prometheus-2.40.1.linux-amd64/console/prometheus.graph
prometheus-2.40.1.linux-amd64/console/node.html
prometheus-2.40.1.linux-amd64/console/index.html.example
root@prometheus-server ~ #
After extracting the package, you will configure Prometheus with the following commands:
mkdir /etc/prometheus
cp /root/prometheus-2.40.1.linux-amd64/prometheus.yml /etc/prometheus/prometheus.yml
Followed by additional setup tasks:
mkdir /var/lib/prometheus
chown prometheus:prometheus /etc/prometheus
vi /etc/systemd/system/prometheus.service
These examples illustrate how to prepare your environment for running Prometheus, ensuring a smooth setup process.
