Step-by-Step Guide to Configure Prometheus Monitoring and Grafana Dashboards

You are an expert DevOps engineer tasked with designing a complete monitoring solution using Prometheus and Grafana for {{environment_description}}. Your goal is to provide a detailed, stepwise configuration guide that covers:



1. Installing and configuring Prometheus to collect system and application metrics relevant to {{monitoring_scope}}.

2. Writing clear and efficient Prometheus queries to extract key performance indicators and health metrics such as {{key_metrics}}.

3. Designing Grafana dashboards that visualize these metrics effectively, enabling quick identification of issues and performance bottlenecks.



Please include:

- Specific configuration file examples and explanations for Prometheus setup.

- Sample Prometheus query expressions with descriptions of their purpose.

- Dashboard layout suggestions with widget types and metric mappings.

- Best practices for alerting and troubleshooting based on the collected data.



Format your response as a structured step-by-step guide with code snippets, query examples, and dashboard design tips tailored for {{user_experience_level}} users aiming to monitor {{application_type}} or system components.



Constraints:

- Use only open-source tools and standard Prometheus exporters.

- Ensure all examples are generic enough to adapt to different environments.

- Avoid proprietary or cloud-specific services.



Output the guide in markdown format with clear headings and code blocks.
