Context

Customer wanted to gain better visibility into their information system. Until then, no centralized monitoring solution was in place, which complicated incident analysis and slowed down decision-making.

Problem

The IT system suffered from sporadic latency, slowdowns, and opaque overall activity. It was impossible to quickly identify bottlenecks or the most resource-intensive applications.

Solution

  • I designed and deployed a complete observability stack:

  • - Umami to collect analytics and track user behavior in real time.

  • - Prometheus to aggregate system and application metrics.

  • - Loki + Alloy to centralize and index logs from all services.

  • - Grafana to visualize metrics and provide teams with a clear and interactive dashboard.

  • - Automated alerting via Prometheus + Slack to be notified as soon as a critical threshold is crossed.

Impact

  • Detection and removal of unnecessary processes, freeing up 15% of RAM.
  • Identification of the most resource-intensive applications, enabling optimization prioritization.
