Caution:
The graphical output of statistics values in Microsoft Internet Explorer is only possible as of version 10.
WebAdmin can display up to ten statistic collectors in a chart. To do this, proceed as follows:
- In the property dialog of a statistic collector, choose the action "Show Chart" to display the values of the collector in a chart.
- Using the checkboxes in the first column, select up to ten statistic collectors from the list of statistic collectors and then choose the action "Show Chart" in order to display the values for these collectors in a chart.
Before displaying the chart, you can also define the following parameters:
Parameter | Meaning |
|---|---|
Time Range | Choose a time range from 1 hour through to 1 year or "All" for the statistic values that are to be displayed. Caution: The graphical display of thousands of values can take a few seconds and may possibly cause the termination of Java Script routines in the browser. If this is the case then you should choose a smaller time range. |
Show multiple value axis | This option is only available if you are displaying multiple collectors in the chart. It permits the optimum scaling of the curves of collectors whose values have different units, e.g. load in percent compared to CPU time in microseconds. |
Poll statistic values | This option is of use if a running UTM application or UTM cluster application is to be monitored. |
Show graph bullets | This option is useful when the chart contains only a few data points. Otherwise, it's better to display only thin lines without shading. |
Now choose the action "Refresh Data" to display the chart.
Each polled statistic value appears as a node in the graphic; neighboring nodes are connected by a line. The x-axis (horizontal) of the graph corresponds to the time, while the y-axis (vertical) corresponds to the scaled values of the statistic collector.
Below the chart you will see a key describing the curves displayed in the chart.
If the curves of more than one statistic collector are displayed in the graph then the individual curves are displayed in different colors (red, green, blue etc. in the sequence in which the collectors were selected). The key below the graph indicates which curves correspond to which statistic collectors.
If a threshold for a collector displayed in the chart is exceeded then the icon corresponding to the collector in question above the chart is displayed with a red or blue bar.
Zooming in the chart:
- Zooming out:
- Right-click the magnifier icon at the top right of the chart to display the entire time range.
- With the left mouse button held down, drag the right or left slider in the gray bar above the chart to enlarge the displayed section
- Zooming in / displaying a section of the chart
- Left-click in the chart, keep the mouse button held down and select a section that will then be displayed.
- With the left mouse button held down, drag the right or left slider in the gray bar above the chart to reduce the displayed section
Moving the displayed time range:
- Left-click in the light area between the two sliders in the gray bar above the chart, keep the button held down and move the mouse to the right or left.
- Briefly right-click in the gray bar above the chart outside the light area between the two sliders in order to select the midpoint of the displayed time range.
