-Dashboard
-*********
-
-The dashboard gives user an intuitive view of benchmark result.
-
-Purpose
-=======
-
-The basic element to be displayed is QPI a.k.a. QTIP Performance Index. But it
-is also important to show user
-
-#. How is the final score calculated?
-#. Under what condition is the test plan executed?
-#. How many runs of a performance tests have been executed and is there any deviation?
-#. Comparison of benchmark result from different PODs or configuration
-
-Templates
-=========
-
-Different board templates are created to satisfy the above requirements.
-
-Composition
------------
-
-QTIP gives a simple score but there must be a complex formula behind it. This
-view explains the composition of the QPI.
-
-Condition
----------
-
-The condition of a benchmark result includes
-
-* System Under Test
-
- * Hardware environment
- * Hypervisor version
- * Operation System release version
- * System Configuration
-
-* Test Tools
-
- * Release version
- * Configuration
-
-* Test Facility
-
- * Laboratory
- * Engineer
- * Date
-
-Conditions that do NOT have an obvious affect on the test result may be ignored,
-e.g. temperature, power supply.
-
-Stats
------
-
-Performance tests are actually measurement of specific metrics. All measurement
-comes with uncertainty. The final result is normally one or a group of metrics
-calculated from many repeats.
-
-For each metric, the stats board shall consist of a diagram of all measured
-values and a box of stats::
-
- ^ +------------+
- | | count: ? |
- | |average: ? |
- | | min: ? |
- | X | max: ? |
- | XXXX XXXX X XXXXX | |
- |X XX XX XX XXX XXX XX | |
- | XXXXXX X XXXXX XX | |
- | | |
- | | |
- | | |
- | | |
- | | |
- +---------------------------------------------> +------------+
-
-The type of diagram and selection of stats shall depend on what metric to show.
-
-Comparison
-----------
-
-Comparison can be done between different PODs or different configuration on the
-same PODs.
-
-In a comparison view, the metrics are displayed in the same diagram. And the
-parameters are listed side by side.
-
-Both common parameters and different parameters are listed. Common values are
-merged to the same cell. And user may configure the view to hide common rows.
-
-A draft design is as following::
-
- ^
- |
- |
- |
- | XXXXXXXX
- | XXX XX+-+ XXXXXXXXXX
- | XXX +XXXX XXXXX
- +-+XX X +--+ ++ XXXXXX +-+
- | X+-+X +----+ +-+ +----+X
- |X +--+ +---+ XXXXXX X
- | +-------+ X

-Time line
----------
-
-Time line diagram for analysis of time critical performance test::
-
- +-----------------+-----------+-------------+-------------+-----+
- | | | | | |
- +-----------------> | | | |
- | +-----------> | | |
- | ? ms +-------------> | |
- | ? ms +------------>+ |
- | ? ms ? ms |
- | |
- +---------------------------------------------------------------+
-
-The time cost between checkpoints shall be displayed in the diagram.
