Dashboard Settings
Using the Dashboard Settings window, you can configure the debug level via the Logs tab, the percentile settings for percentile graphs via the Percentile tab, the percentile settings for transactions via Transaction Details tab, favorite settings via the Favorite Settings tab, graphs gradient settings via Graph Settings tab, and graph tree refresh settings via Graph Tree Settings tab.
Logs
This tab is used to configure the debug levels for logs. You can select the debug level from 0 to 4. This defines the information level to be stored at trace level. The default level is 0, which contains the most basic information. Further levels (i.e., 1, 2, 3, and 4) contain information that is more verbose as the level increases.
To configure the debug level of server logs and dashboard server logs, select the debug level from the Debug Level section. For Module Debug Level, first select the module name and then select the debug level for that module.
Percentile
A percentile is the value of a variable below which a certain percent of observations fall. Therefore, the 20th percentile is the value (or score) below which 20 percent of the observations may be found. The pth percentile is a value so that roughly p% of the data is smaller and (100-p) % of the data is larger. Percentiles can be computed for ordinal, interval, or ratio data.
To configure the percentile view for a percentile graph, click the Percentile tab on the Configuration Settings window. The Percentile setting section is displayed.
The default percentile views are displayed. Select the percentile to view from the drop-down list. To select all percentile views, select the Select All checkbox. To view the default percentile, select the Select Default Percentiles button. To save the configuration setting in the Config file, select the Save In Config File check box. Apply the settings by clicking the OK button. To cancel the settings, click the Cancel button.
Example:
In case you select 90, 85, 80, and 70 as percentile views and apply the settings.
The percentile graph is displayed with the selected percentile views.
To view the percentile views, open a graph and change the graph type to percentile graph from the widget settings. Once the percentile graph is displayed, double-click the graph to view the lower pane. The percentile views configured are displayed in the lower pane.
Transaction Details
You can also configure percentile views for transactions as configured for graphs in the above section. To configure percentile view for the transactions, click the Transaction Details tab on the Configuration Settings window. The Transaction Details section is displayed.
Provide the following inputs:
- To view the transaction details in Auto mode, select the Transaction Details in Auto Mode check box.
- Select the Show selected percentiles check box to enable the percentile data creation for transactions.
- To view the default percentiles, click the Select Default Percentiles You can select the percentile to view from the drop-down list.
- You can also select all percentiles to view by using the Select All
- You can also provide a refresh time interval for transaction percentile and threshold for transaction details pagination in the respective input areas.
- To save the configuration setting in the Config file, select the Save In Config File check box.
- Apply the settings by clicking the OK To cancel the settings, click the Cancel button.
Example:
In case you select 99, 95, 90, and 80 as percentile views for transactions and apply the settings.
The selected percentile views are displayed in the Transaction summary report.
To view the Transaction summary report, go to View menu, and click the Transactions menu item. Then, click the All Transactions link or a particular transaction link.
Favourite Settings
You can specify whether to apply the default time of favorite or the time specified in the current view. You can also specify whether to load favorites with compare settings. It also provides a feature to enable dynamic Dashboard. For these settings, you need to click the Favorite Settings tab on the Configuration Settings window. The Favorite Settings section is displayed.
If you select the Load Graph Time Settings From Favorite checkbox, the graph time settings are loaded from favorite. If you do not select this check box, no time of the favorite is saved and the system considers the last saved value (default value). For example, if the current view of the favorite is last 1 hour and the default view is last 4 hours. Then, on selecting this checkbox, the favorite current value i.e., last 1 hour is saved and on not selecting this check box, no value of the favorite is saved and the system takes the last specified value (default value) i.e., last 4 hours on loading the favorite.
Note: If you apply comparison and save it as favorite, then, on selecting the Load Favorite with Compare Setting check box, the favorite is loaded with compare settings.
The Dynamic Dashboard feature allows a user to view the most recent updates in the graphs. You can enable dynamic Dashboard by selecting the Enable Dynamic WebDashboard checkbox. On enabling this, the graphs are displayed based on the runtime changes.
You can also specify Refresh Interval for Dynamic WebDashboard in minutes.
To save this setting in the configuration file, select the Save in Config File check box. Click OK to apply the settings.
Metrics Settings
You can also specify whether to apply gradient color on chart types and up to how many decimals the value is to be displayed on the y-axis. For this, you need to click the Graph Settings tab on the Configuration Settings window. The Metrics Settings section is displayed.
Note: Here, you can apply gradient color settings for the graphs, configure the decimal digits, and can enable/disable crosshair and gridline settings.
In the Advanced Settings section, you can configure the following settings:
- Shared Tooltip Threshold: To enable multiple tooltips for different graphs in a single widget.
- Series Boost Threshold: To decrease the width of graphs when a given threshold for number of graphs is crossed.
- Graph Scaling: To enable the scaling on widgets so that the lowest value graphs become visible in front of higher value graphs.
Note: Filter and Sorting options are available in the Scaling column to filter out scaled values of common scaled factors.
- Lower Panel Pagination and Threshold: To enable the pagination in the lower panel of the Dashboard and threshold of the pagination.
- Scaling Threshold: To define the graphs on which scaling is applied. It allows you to scale graphs using different threshold values.
Example: If the scaling threshold is 20 and the max value of the graph is 100 then all the graphs having values lesser than 100/20 are scaled with the Scaling factor Nx1. All the graphs having values greater than 100*20 are scaled with a Scaling factor shown like Nx2 or Nx/3.
Scaling threshold value in Dashboard:
- Inter-widget Delay Time (ms): Whenever a new sample arrives on a production test, then graphs are updated one by one with the given delay.
- Enable Monochromatic Color: To enable monochromatic colors in Advance settings.
Example: Applied gradient color on Donut chart.
Note: To configure the decimal digits to be displayed with graphs, specify the value in the Show Decimal Digits text box.
Example: Crosshair and Gridlines
To enable crosshair and gridlines, select the respective options. Once you hover the mouse, crosshair is displayed.
In the below figure, decimal digits (3), grid lines, and crosshair are displayed.
Scale
This feature is added to reduce the visualization and interpretation complexities arising from having a large as well as small graph values on the same widget. Scaling enables distinct display of very small values compared with very high values on the same widget. Two scaling modes are provided, logarithmic and auto.
To enable scaling for all widgets, go to Settings > Graph Settings, and enable Graph Scaling.
Note: Once scaling is enabled, 
icon is displayed over the widget.
Key Pointers
- Scaling can be changed/applied from the widget.
- If scaling option is changed/applied from the widget, then it is applicable on that widget only.
- If scaling by specified metrics is selected, then on the selection of metrics from the lower pane or from widget, the scaling is changed.
- From the configuration UI, you can change the default option of scaling.
- Using the Scaling Threshold value, you can scale the graph as and when needed and can calculate the Scale Factor based on that.
- The graphs, which are being scaled, are displayed with the dash and dotted line respectively.
- The scale factor is being calculated and it could be seen in the lower panel as ‘X’ (Scaled up) and ‘/’ (Scaled down), based on the nature of the graphs.
- The scale factor is displayed in whole numbers.
- A specific range is maintained for the graphs where scaling is applied and maximum graphs will have the Scale Factor as 1. For example: If the scaling threshold is 20 and the max value of the graph is 100 then all the graphs having values lesser than 100/20 are scaled with the Scaling factor Nx1. All the graphs having values greater than 100*20 are scaled with Scaling factors shown like Nx2 or Nx/3.
Example:
In the graph panel, there is a graph with low values (CPU Utilization) and hence it is difficult to view the graph data concerning the higher valued graphs.
To have a better view, you can apply scaling on the graphs. To do this, enable the scaling via Settings > Graph Settings, and enable Graph Scaling with scale factor. There are two modes of scaling – Auto and Logarithmic.
Auto
This mode is applied to the graph having the highest value.
Note: The scaling factor is calculated and displayed in the lower panel automatically. To find the actual value at any instance, mouse over to that instance. You can change the scaling base metric by clicking if from the lower panel. Scaling is re-calculated according to the selected metric and redraws the chart.
Logarithmic
Here we can use logarithmic scaling to handle the large number of metric or graphs. In mathematics, the logarithm is the inverse operation to exponentiation, just as division is the inverse of multiplication and vice versa. That means the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number. In simple cases, the logarithm counts factors in multiplication. For example, the base 10 logarithm of 1000 is 3, as 10 to the power 3 is 1000 (1000 = 10 × 10 × 10 = 103); 10 is used as a factor three times.
Scaling Off
To disable scaling from the graphs, select Off from the scale menu. This laid the graphs in their original form.
Area Range Graph
Area Range graphs is a chart type, which is applicable based on the configured threshold. This is implemented to resolve the UI slowness due to the large number of graphs on the panel. The area-range graph plots the higher value and lower value samples from a set of graphs, which makes it lightweight and quick to update and render.
Geo Country Map
This shows the map of the country which is selected in the Widget.
Widget Metric Limit
It shows the limit of the Widget plotted.
Widget Count limit
This shows the limit of the count in the widget.
Shows data points
In this, the data point is shown in the graph if samples are below the given limit.
Apply Zoom: Select this check box to apply Zoom on the widget.
Offset line: Select this check box to show the offset line.
Metrics Tree Settings
You can specify whether to refresh the graph tree on the occurrence of run time changes. In addition, you can also specify at what level, compare group members to be displayed.
For this, you need to click the Metrics Tree Settings tab on the Configuration Settings window. The Metrics Tree Settings section is displayed.
Note: This option allows you to set the maximum level in the tree hierarchy by which “Compare Group Member” related context menus are shown. This is required as there is an impact on the performance of Dashboard when “Compare Group Member” is shown in the tree and the hierarchy level is high (>5). Default value is -1, which means it is allowed at all the levels.
DB Settings
