 ### Prometheus and Grafana
 
-[Prometheus](<>) is a robust open-source monitoring and alerting tool used to collect, store, query, and alert on time-series data. It employs a pull-based model to gather metrics from instrumented targets and features a powerful query language (PromQL) for data analysis. It enables developers to monitor various aspects of their systems, including metrics, performance, and health.
