+The longhaul tests are designed to run for a period of a week, validating the stability of Dapr and its components, while measuring resource utilization and performance over time.
+
+## Public Dashboard
+
+You can access the live longhaul test results on the public Grafana dashboard. This dashboard is updated in near real-time, showing the latest results from the longhaul tests.
