-This guide describes how to set up NVFLARE metrics publishing to StatsD Exporter, which then can be scraped by Prometheus and visualized with Grafana.
+FLARE Monitoring provides a initial solution for tracking system metrics of your federated learning jobs.
+Different from Machine learning experiment tracking, where it focused on the training metrics, the monitoring here focused on the FL system: i.e. job and system lifecycle metrics.
