+Continuous Performance Measurements and Trending
+------------------------------------------------
+
+Performance analysis and trending execution sequence:
+`````````````````````````````````````````````````````
+
+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/.

+Parameters to specify:
+``````````````````````
+
+- job to be monitored - the Jenkins job which results are used as input data for
+  this test;
+- builds used for trending plot(s) - specified by a list of build numbers or by
+  a range of builds defined by the first and the last buld number;
+- list plots to generate:
+
+  - plot title;
+  - output file name;
+  - data for plots;
+  - tests to be displayed in the plot defined by a filter;
+  - list of parameters to extract from the data;
+  - periods (daily = 1, weekly = 5, monthly = 30);
+  - plot layout
