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 (or DPDK) 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 (and DPDK) 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 an algorithm which divides test runs
into groups according to minimum description length principle.
The trend value is the population average of the results within a group.
Failed tests
------------
The table lists the tests which failed over the <N=14> runs of the trending
jobs.
Legend to the table:
- **Test Case**: name of FD.io CSIT test case, naming convention
`here <https://wiki.fd.io/view/CSIT/csit-test-naming>`_.
- **Fails [#]**: number of fails of the tests over the period.
- **Last Fail [Date]**: the date and time when the test failed the last
time.
- **Last Fail [VPP Build]**: VPP build which was tested when the test failed
the last time.
- **Last Fail [CSIT Build]**: the last CSIT build where the test failed.

Dashboard
---------
Legend to the tables:
- **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.
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.
