Statistics display
The following is a summary of how to use the statistics display. Details of what each statistic means are after this summary.
- When there are large numbers of individual statistics for a particular object, two or more tabs at the top of the display divide these into major categories. Click on a tab to view the statistics in that category.
- To change the time-period displayed, use the radio buttons at the top of the window. You can choose from Last day, Last month, and Last year.
- For Last day, the line graph covers the previous 36 hours (if available).
- For Last month, the line graph covers the previous six weeks (if available).
- For Last year, the line graph coversthe previous 15 months (if available).
- The value of a counter statistic is the number of events per hour.
- If you want to see a larger graph of a particular statistic, click the + symbol at the top-right corner of that line graph. A new window is opened containing just that graph. (Note that if you are running the Windows version of the EMS System Explorer, these enlarged line graph windows do not appear on the Windows taskbar.) If you hold down the left-click button of your mouse and drag a box over the line graph, the display zooms in on that section. To zoom out, hold down the left-click button of your mouse and drag a box over the line graph in a different direction (such as up and left instead of down and right).
- To find out the exact value of a point on the line graph, hover your mouse pointer over that point. The EMS System Explorer displays a tooltip containing the timestamp for that data point (the start of the period it covers), and the value.
- The line graphs consist of a number of data points joined together. For Last day, each data point covers a 5-minute period. For Last month, each data point covers a 1-hour period. For Last year, each data point covers a 1-day period.
- If a value is not available for a particular data point, the line graph connects the two data points either side directly. A value may not be available if, for example, the EMS was not running or the NE performed a Software Protection Switch.
