Prometheus Monitoring
Learn how to deploy Prometheus, collect host metrics with Node Exporter, query time-series data with PromQL, and configure alerting with Prometheus and Alertmanager. This course gives you a practical monitoring foundation for modern Linux and infrastructure environments.
Why It Matters
Good operations work depends on measurable system behavior, not just reactive troubleshooting. Prometheus has become a standard monitoring platform for infrastructure and cloud-native environments because it can collect metrics, support alerting, and make operational trends visible over time. Understanding its core workflow is central to modern observability practice.
What You Will Learn
- Install and verify a Prometheus monitoring server.
- Collect Linux host metrics with Node Exporter.
- Query metrics with basic PromQL expressions.
- Configure alert rules to detect meaningful conditions.
- Use Alertmanager to handle and route alerts more effectively.
- Apply these skills in a custom monitoring solution challenge.
Course Roadmap
The course begins with Prometheus installation so you can establish the monitoring server itself. It then moves to Node Exporter, which provides host-level metrics that make Linux resource behavior visible to Prometheus.
Next, the course introduces basic PromQL so you can query and interpret collected time-series data. After that, you define alert rules and then expand into Alertmanager basics so alert handling can move beyond simple threshold detection.
The course ends with the Custom Monitoring Solution challenge, where metric collection, querying, alerting, and operational reasoning are combined into a more complete observability workflow.
Who This Course Is For
This course is for Linux learners, SRE beginners, and DevOps practitioners who need to understand metric-based monitoring rather than relying only on ad hoc system checks.
Outcomes
By the end of this course, you will be able to deploy a basic Prometheus stack, collect and query system metrics, define useful alerts, and understand the core workflow behind modern infrastructure monitoring.
