Furkan Türkal shares his experience of developing a monitoring solution for his xDSL modem using Prometheus Exporter and Grafana Cloud. Faced with frequent internet outages, he sought to identify whether issues stemmed from his ISP or his modem. By leveraging the SSH capabilities of his ASUS DSL-AC51 modem, Türkal successfully scraped modem metrics, transforming them into a Prometheus-readable format. He utilized the go-dsl library to facilitate this process, enabling him to create a custom Prometheus Exporter to bridge the gap between non-Prometheus-compliant applications and the monitoring platform. Türkal configured Grafana Cloud to visualize these metrics and created alerts using Grafana OnCall to notify him of significant changes, such as drops in the SNR margin. His project not only provides personal insights into his network's performance but also serves as an open-source contribution, inviting further development and use by others interested in similar monitoring setups.
