Statistical Console tables and graphs

Graphs

Graphs consist of the following components:

Graph Slider

Sliders

The sliders in StatCon control the horizontal and vertical axes of the graph where the vertical axis is the value of the data (in whatever units the graph is in) and the horizontal axis is time. Each graph has an attached horizontal and vertical slider. The horizontal slider specifies the timeline of the data displayed and the vertical slider specifies the bounds of the data displayed.

 

Graph Indicator

Indicators

Each graph's attached vertical slider contains an indicator for that graph. At runtime, the rightmost edge of the graph data (commonly the most recent data) is displayed by the indicator (the bar on the slider colored the same as the graph). When looking at old data, left-clicking on a horizontal slider causes a vertical black line to appear. This black line defines the point of data the indicators display.

Graph Table

The graph table is a summary of the graph information and allows easy configuration of the graph. Each graph takes up a single row in the table.

Controls table

Controls in the statistical model are shown in the Control table. Each control takes up a single row in the table.

Alerts table

StatCon allows you to add alerts over a metric in your statistical model. Each Alert takes up an entire row in the Alerts table in StatCon. An Alert is a configurable event which is triggered or reset based on the latest value of a metric. To add an alert you must open up the nodes in your trace until you see a graph icon, representing an individual metric. Right-click on the graph icon and select 'Add an Alert over this observation'. You will be promted for a name for your Alert and your newly created Alert will appear in the Alerts table.

Alerts have their own averaging information which is separate from the graph averaging information. This allows you to set an Alert to trigger when the value of a metric has passed a set boundary only over a certain period and after a certain averaging calculation has been applied. This means that you can have fine grained information in your graphs but the Alerts can be set to be average out spikes.

Alerts Table

When an Alert triggers, a warning icon will appear in the table next to it's name. When the Alert resets, the warning icon will disappear. In addition to this, Alerts can be configured with a variety of other actions to be performed when the Alert triggers or resets. Click in the 'On Trigger' column of your alert and then click the '...' button that appears to get to the action configuration dialog. In this dialog you can add and remove trigger and reset actions as you wish using the 'Add' and 'Remove' buttons. You can select the action type from the drop menu and configure it in the panel below. If you wish to test your configuration, simply click the 'Test Now' button.

Common Base Event Log table

Any Common Base Event messages stored within a Trace Agent appear in the Common Base Event Log. Only the following information is written to the log:

Common Base Event Log Table

Common Base Event messages can be saved as a text log using the save button on the left of the log. If at run-time messages are coming in too fast to read, the lock button on the left of the log can be used to temporarily block new messages and show a static log.
