Add statistic

The Add statistic panel is used for adding Statistics to a Chart. See the Statistics Reference for information about each individual Statistic.

	Option	Description
	Components	Lists all statistic holders (components, project, test cases) that provide statistics data and are assigned to this chart. When one of these is selected, second column is populated.
	Statistic data	Lists all Statistic data provided by statistic holder selected in first column. When one of these is selected the third column is populated.
	Metrics	Lists all Metrics that can be applied to the chose Statistic data.
	Data source	Lists all agents that selected variable is available from. This is where user can choose to see the aggregated value from all available agents by selecting All option or just from one particular agent by selecting it from the list.
	Add	Adds selected statistic to the chart.

Zoom

The Zoom panel is used for setting the graduation of time range. By increasing the graduation, time range is smaller, but more details can be seen.

	Option	Description
	All	Displays all data from the beginning of test.
	Weeks	Sets time scale to weeks.
	Days	Sets time scale to days.
	Hours	Sets time scale to hours.
	Minutes	Sets time scale to minutes.
	Seconds	Sets time scale to seconds.

Scale

The Scale panel is used for setting vertical scale of statistics within a chart. Scaling is done by multiplying the actual data values by scale factor and it can be done independently for each statistic.

	Option	Description
	Scale combo	Sets scale by picking the scale factor from the list.
	Scale slider	Sets scale by moving slider.

Style

The Style panel is used for setting chart lines style (color, stroke, width). Each statistic has its own style.

	Option	Description
	Color	Sets the line color by picking color from the drop down menu.
	Width	Sets the line width by moving slider. Default is 1px.
	Stroke	Sets the line stroke. Available strokes are: solid, dashed and dotted.

Raw data

The Raw data panel is used for exporting raw chart data in CSV format.

	Option	Description
	Export raw data	Opens the file dialog where user specifies the export location. If specified file already exists user is asked for confirmation to replace it. Complete data, for the entire test, of all statistics assigned to a chart are exported.

LoadUI allows you to compare old Results with each other and with the live statistics generated from the current run. Before reading this article, we recommend that you know how The Results Window work.

How to compare Results

From the Analysis view, click on the Compare Results button found close to the upper left corner:

This will bring up the Result Selector containing all your previous Results, as shown below:

Comparing two results is now as easy as selecting one Result from the left set (this will be the Primary Result) and one from the right set (this will be the Compared Result) and then click Load data. All charts will now show duplicate lines for each Statistic – lines from the Primary Result will show in their original color while the corresponding lines from the Compared Result will appear in a slightly darker shade:

Notice that the names of the Primary Result and the Compared Result will always be shown on the left and right side of the Result Selector button respectively:

Selecting Current run as the Primary Result instead of an old Result will allow you to compare live statistics from the current run (if you have a project running) with an old Result.

Clicking Clear will clear any selection made in the right set, so that you can go back to just watching a single Result.

As always, don't forget to have fun!

Opening the Statistics Workbench

Open the Statistics Workbench by clicking the button that looks like a bar chart in the Project view:

The Statistics Workbench has two views (or states if you like), which we will now go into with more detail.

The Results view

The Results view lets you manage Results of a project. From here, you can access statistics from stored Results as well as from the current run (by double clicking their icons). For a tutorial on how to use this view, please refer to Managing Stored Results.

The Results view without any previous Results.

The Results view with two recent and one archived Result.

The Analysis view

Double clicking a Result or the current run in the Result view will open that Result in the Analysis view. From here you have full access to statistic data from any component and agent at any given point in time!

The Analysis view without any Charts added.

The Analysis view showing one Chart together with a sub chart.

The Analysis view is layered on top of the Results view in the same way that the Project view is layered on top of the Workspace view. Thus, clicking the close button will "go back" to the underlying Results view:

The close button of the Results view.

To learn how to use the Analysis view, please refer to the Analysis view.

Preparations

Before starting this tutorial, you need to know the basics about the Statistics Workbench.

Create a new project with a Fixed Rate Generator connected to a Web Page Runner. Set the Generator's rate to 10/Sec, name the Runner My Runner and point it to some URL. Start the project in by clicking the Play button and let it stay running during the whole tutorial.

Showing Statistics from a component

Open the Statistics Window and enter the Analysis view. Locate the icon representing My Runner in the left toolbar and drag it into the empty space to the right:

This will create a Chart containing My Runner. A Chart can show all the Statistics of its contained Components.

By default a Chart will show the Statistic Average Time Taken of a containing Web Page Runner; this is why there's already a line in the Chart.

Click Add Statistic to add another Statistic from My Runner:

This will toggle the Add Statistic Panel. Specify which Statistic you want to add by clicking Sent, Per Second and All. You have now specified a Statistic that will show the Sent requests per second for My Runner.

Click Add to add the specified Statistic to the Chart:

A new line will appear in the Chart, together with a new legend called Sent/s.

Playing around

The new Statistic will stay steady at the value 10 since you previously set the Fixed Rate Generator in your project to 10/Sec. Let's lower the rate of the our generator to 1/Sec while keeping the Statistics Window open:

As expected, the Statistic showing My Runner's Sent Requests per second falls to 1 as well:

Also, use the horizontal scrollbar to go back to the beginning of the test (the X-axis should show 00:00). Notice that when the scrollbar is positioned to the far right, the chart will be always show the most recent datapoints as the test goes on. All other scrollbar positions will fixate the chart at that specific time interval.

Removing Statistics

Now remove the Average TimeTaken (abbreviated TimeT Avg) Statistic by dragging it to the black hole in the upper right corner to delete them:

What's next?

There's a lot more to the Analysis view, so take a deep breath and then proceed reading The Analysis view, continued.

As always, don't forget to have fun!

If you are not familiar with the Results Window and its two views, we suggest that you read about the Results Window before starting this tutorial.

For the purpose of this tutorial, the current project has previously been run three times and the Results view has been opened. The individual runs were started 09:43, 11:04 and 11:42 respectively, as reflected in the Result’s names below.

Archiving a Result

Having a list of automatically saved recent results can be handy, but since loadUI only saves a limited number of results automatically (before deleting the oldest one) you should know that you can archive Results. Archiving a Result will not just prevent loadUI from ever deleting it, but also lets you rename Results for easier access.

If you want to archive a Result, simply drag and drop it from the Recent Result container to the archived Results container. You don’t have to rename the Result, but we encourage it since it’ll make it easier to find it later on. Renaming is almost as easy; just click the text on the Result’s top border and click Rename:

After archiving and renaming one of the recent Results, the Results view will look something like this:

The Manage Results view with two recent and one archived Result.

Change settings

Click the Settings button in the upper right part of the Results view to bring up the settings dialog:

From this dialog you can specify where in the file system you want Results to be saved and how many results loadUI should automatically save per project, before deleting the oldest unarchived Result.

The current result will however always be be saved to disk regardless of this setting, since the Statistics Workbench requires disk data to function . If you are willing to sacrifice the Statistics Workbench on the altar of disk space, provide this command line option to loadUI:

-Dloadui.statistics.disable=true
