During the summer travel season, keeping an eye on currency exchange rates is crucial for travelers looking to maximize their spending power abroad. This guide introduces the use of Grafana, a visualization and monitoring tool, in conjunction with Prometheus and Grafana Cloud, to track and visualize forex rates. By leveraging data from openexchangerates.org, users can expose exchange rates as Prometheus metrics and visualize them through Grafana dashboards, with the added capability of setting up alerts for rate fluctuations. The process involves setting up a Grafana Cloud account, configuring a forex Prometheus exporter, and using Grafana Alloy to scrape metrics. This setup not only helps travelers stay informed about rate changes but also showcases Grafana Cloud’s capabilities in managing metrics, logs, and dashboards, offering a practical and user-friendly approach to monitoring financial trends during travel.
