Case Study: Optimizing Web Traffic with Nginx + Python

• Challenge – A media streaming client experienced 30 % packet loss during peak hours.
• Solution – Senior admin implemented Nginx reverse proxy with rate‑limiting rules, then deployed a Python‑based traffic analyzer (pandas + scapy) to identify bottleneck patterns.
• Result – Reduced packet loss to <2 % and improved average throughput by 22 % within two weeks.
• Key takeaways – Combining Nginx’s lightweight proxy capabilities with custom Python analytics enables rapid performance gains without hardware upgrades.

Essential Monitoring & Alerting stack

• Metrics – Prometheus node_exporter, Windows exporter, VMware vSphere exporter.
• Visualization – Grafana dashboards segmented by OS, hypervisor, and web server.
• Alert routing – Alertmanager to PagerDuty for on‑call escalation; custom Python webhook for Slack notifications on critical events.
• Log aggregation – elastic Stack (Filebeat → Logstash → Elasticsearch) plus Python parsers for non‑standard log formats.
