Performance analysis and trending execution sequence:
`````````````````````````````````````````````````````
-1. Triggered at completion of Performance Measurements and Archiving (PMA) job.
-
- a. Periodic, or gerrit triggers are supported too.
-
-2. Download RF output.xml from triggering CPM job.
-3. Parse out the test results listed in PAL specification file.
-4. Reads specified amount of PMA historical data from Nexus.
-5. Calculate specified statistical metrics – see next section.
-6. Evaluate latest results against the historical metrics, quantify relative
- change and based on defined criteria set the result to Pass (no-change or
- progression) or Fail (regression).
-7. Add the new data to historical data.
-8. Generate a new set of trend analysis summary and drill-down graphs.
-9. Archive the latest RF output.xml to nexus for future analysis.
-10. Publish trend analysis graphs in html format on https://docs.fd.io/.
+CSIT PA runs performance analysis, change detection and trending using specified
+trend analysis metrics over the rolling window of last <N> sets of historical
+measurement data. PA is defined as follows:
+
+ #. PA job triggers:
+
+ #. By PT job at its completion.
+ #. Manually from Jenkins UI.
+
+ #. Download and parse archived historical data and the new data:
+
+ #. New data from latest PT job is evaluated against the rolling window
+ of <N> sets of historical data.
+ #. Download RF output.xml files and compressed archived data.
+ #. Parse out the data filtering test cases listed in PA specification
+ (part of CSIT PAL specification file).
+
+ #. Calculate trend metrics for the rolling window of <N> sets of historical data:
+
+ #. Calculate quartiles Q1, Q2, Q3.
+ #. Trim outliers using IQR.
+ #. Calculate TMA and TMSD.
+ #. Calculate normal trending range per test case based on TMA and TMSD.
+
+ #. Evaluate new test data against trend metrics:
+
+ #. If within the range of (TMA +/- 3*TMSD) => Result = Pass,
+ Reason = Normal.
+ #. If below the range => Result = Fail, Reason = Regression.
+ #. If above the range => Result = Pass, Reason = Progression.
+
+ #. Generate and publish results
+
+ #. Relay evaluation result to job result.
+ #. Generate a new set of trend analysis summary graphs and drill-down
+ graphs.
+
+ #. Summary graphs to include measured values with Normal,
+ Progression and Regression markers. MM shown in the background if
+ possible.
+ #. Drill-down graphs to include MM, TMA and TMSD.
+
+ #. Publish trend analysis graphs in html format on
+ https://docs.fd.io/csit/master/trending/.
