+VPP Performance Dashboard
+=========================
+
+Description
+-----------
+
+Dashboard tables list a summary of latest per test-case VPP Maximum
+Receive Rate (MRR) performance trend, trend compliance metrics and
+detected number of anomalies. Data samples come from the CSIT VPP
+performance trending 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.
+
+Legend to table:
+
+    - **Test Case** : name of CSIT test case, naming convention in
+      `CSIT wiki <https://wiki.fd.io/view/CSIT/csit-test-naming>`_.
+    - **Trend [Mpps]** : last value of trend.
+    - **Short-Term Change [%]** : Relative change of last trend value
+      vs. last week trend value.

+offered by traffic generator over a set trial duration, regardless of
+packet loss.
