Case Study: NOS improves mobile network troubleshooting with Grafana

How the telecommunications and media company NOS uses Grafana to troubleshoot its mobile network

NOS, the Portuguese telecommunications and media company, needed a faster, more flexible way to analyze the growing complexity of its mobile network. As services, nodes, and technologies multiplied, its engineers struggled with slow, static reporting and limited filtering when troubleshooting network issues and optimizing performance.

NOS implemented Grafana Open Source, along with Grafana Loki for log centralization and Prometheus for metrics, to make data easier to query and correlate across network domains. With Grafana, engineers can analyze data in seconds instead of minutes, and the company reports an 80% decrease in query time, while about 30 radio network engineers now use Grafana daily to speed troubleshooting and improve customer experience.
