VPP Performance Dashboard
=========================

Description
-----------

Performance dashboard tables provide the latest VPP throughput trend,
trend compliance and detected anomalies, all on a per VPP test case
basis.  Linked trendline graphs enable further drill-down into the
trendline compliance, sequence and nature of anomalies, as well as
pointers to performance test builds/logs and VPP builds. Performance
trending is currently based on the Maximum Receive Rate (MRR) tests. MRR
tests measure the packet forwarding rate under the maximum load offered
by traffic generator over a set trial duration, regardless of packet
loss. See :ref:`trending_methodology` section for more detail including
trend and anomaly calculations.

Data samples are generated by the CSIT VPP performance trending jobs
executed twice a day (target start: 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 FD.io CSIT test case, naming convention
      `here <https://wiki.fd.io/view/CSIT/csit-test-naming>`_.
    - **Trend [Mpps]** : last value of performance trend.
    - **Short-Term Change [%]** : Relative change of last trend value
      vs. last week trend value.
    - **Long-Term Change [%]** : Relative change of last trend value vs.
      maximum of trend values over the last quarter except last week.
    - **Regressions [#]** : Number of regressions detected.
    - **Progressions [#]** : Number of progressions detected.
    - **Outliers [#]** : Number of outliers detected.

Tested VPP worker-thread-core combinations (1t1c, 2t2c, 4t4c) are listed
in separate tables in section 1.x. Followed by trending methodology in
section 2. and trendline graphs in sections 3.x. Performance test  data
used for trendline graphs is provided in sections 4.x.
