Prometheus + Grafana Monitoring

Production-style monitoring project for a mixed Linux and Windows environment using Prometheus, Grafana, node_exporter, and windows_exporter.

This repository documents a real lab setup built on Ubuntu Server and a Windows host. It includes installation steps, Prometheus configuration, Grafana dashboard documentation, working PromQL examples, and troubleshooting notes based on the actual build process.

Practical Outcome

The project results in a working monitoring stack with:

• Linux and Windows metrics in Prometheus
• Grafana dashboards with live metrics
• Dynamic Windows dashboard filtering by server and disk
• Troubleshooting-backed PromQL that was tested against a real environment
• Documentation suitable for GitHub, portfolio use, and future setup reuse

Notes

• This repository is focused on the technical monitoring implementation only.
• It is suitable as a portfolio project, lab reference, or base for future observability work.
• Screenshots should be taken only after masking sensitive IPs, hostnames, usernames, or internal labels if you plan to share them publicly.
