-VPP MRR Performance Dashboard
-=============================
+VPP Performance Dashboard
+=========================
Description
-----------
-Dashboard tables list a summary of per test-case VPP MRR performance
-trend and trend compliance metrics, and detected number of anomalies.
-Data samples come from the CSIT VPP trending MRR jobs executed twice a
-day, every 12 hrs (02:00, 14:00 UTC). All trend and anomaly evaluation
-is based on a rolling window of <N=14> data samples, covering last 7
-days.
