The type of graph displayed is determined by the option selected from the radio buttons above the Statistics Element Display. The options for the type of graph displayed can also be changed at any time from the Display Menu of the Real-Time Stats Graph Window.
Depending on the selected graph type, the statistics display in one of the Real-Time Stats Graph Windows, shown in
Figure 6.2, Figure 6.3, and Figure 6.4. Plot Graph
This option displays the statistics as a plot graph. The x-axis represents the time, and the y-axis represents the value. Values plotted are based on the selected Data Mode.

Peg Counts
Peg Counts display total accumulated event counts. These are incremented at each accumulation period.

Bar Graph
The Bar Graph provides a three-dimensional statistics graph. The lowest of the two numbers represents the most recent accumulation period values, and the high value at the end of each bar represents the maximum values reached for any accumulation period. Values are based on the selected Data Mode. In Figure 6.4 the x-axis represents the count, and the y-axis represents the network element. Graph orientation, planes, and appearance can be modified from the Resources menu, as explained in Lab 6.2.

Once the statistics display in any of the graph windows, the following actions are available from the pull-down menus. The File menu allows the statistics display to be printed or
saved to a file, or exit from the Real-Time Stats Graph Window.
• Open Data opens an existing data file.
• Save Data saves the displayed graph to a file.
• Save Data As saves the displayed graph to a new file
with a different name than a previously saved version.
• Delete Data accesses a dialog box to choose
previously saved data to delete.
• Print prints the displayed graph to a printer.

Use the Display menu to set the current display to Plot Graph, Bar Graph, or Peg Counts. This option does not open up a new window, but replaces the current window display.
The Data menu provides options to pause and clear displayed data.
• Use Pause Data to pause and resume data display. When this menu option is selected, no statistical data is counted or appended to the display. A small toggle button next to the menu option indicates that data display is paused. Click on the toggle button again to resume data display.
• Use Global Reset to clear all data from the graph in the active window, then continue graphing new data.

Network Performance Statistics and ReportsThe Graph Resources menu allows the appearance of the graph to be defined, including the presence of the X and Y axes, the presence of a legend, the presence and appearance of a background grid for the X and Y axes, appearance of the bars in bar graphs, the time interval and time period for which statistics are graphed. When the Graph Resources option is selected from the Resources menu, either the Stats Plot Graph Resources window or the Stats Bar Graph Resources window appears, depending on the type of graph display selected.

This lab focuses on the steps to display Real-Time Statistics in a plot graph.
1. In Network Status mode, choose Real-Time from the Statistics Menu. Choose Configure from the Real-Time Statistics submenu. You may also click on the Real-Time Statistics icon on the SpImain. The Real-Time Statistics Setup Window appears.

3. Click the toggle button next to Link to display only Core SS7 statistics for links. If the toggle buttons next to Linkset, Node, SpIprobe, and Signalling Groups are selected, toggle these options off.
When you have specified these options, the relevant statistics categories display in the Statistics Category list.
4. In the Statistics Category List, click Link: FISU Count in the list to select it. Scroll down through the list with the scroll bar if it is not visible. You can only select one statistic at a time. 5. Click Add to add the statistics category to the Statistics
Object Display area, the empty area on the right side of the window. The FISU Count stats object is listed by name in this area. The window next to its name is a drop box. Other statistics you add to the Statistics Object Display area display in the same Stats Graph window as the FISU Counts.
6. To view statistics for particular nodes, links, linksets, or signalling groups, you must specify these network elements. To specify the links for the FISU counts, click the El Paso to
Amarillo link and El Paso to Laredo link on the network
map. Drag the linksets to the Element drop box and release the mouse button when the drag and drop icon is above the drop box for the FISU Counts.
Different network elements can be dragged and dropped onto the drop box for each statistics category, or the same network elements can be selected for each statistic.

7. Repeat step 4 through step 6 to add Link: MSU Count to the Statistics Object Display area.
When you’re finished, the Real-Time Statistics Setup Window should match Figure 6.7.

8. In the FISU Count Statistics Element drop box, click the El
Paso-Laredo link with the left mouse button. Then click the
right mouse to display the pop-up menu.

11. From the pop-up menu, select Delete this stats object. The
Link: FISU Count object is deleted from the Statistics
Object Display area.
12. Repeat step 4 through step 6 to re-assign the Link: FISU
Count to the Statistics Object Display area.
When all statistic categories and network elements have been selected, define the parameters to set up the statistics display. These are located in the upper right side of the screen above the Statistics Object Display area. These parameters apply to all selected statistics and network elements.
13. Click the Default Rate toggle button to select the default accumulation rate for the FISU and MSU counts. The accumulation rate can also be set from the Resources menu in the Real-Time Stats Graph window.
14. Select Per Second for the Data Mode.
15. Enter 0 hours and 45 minutes in the History field. This is the period for which data will be retained in the buffer for the statistics selected. That is, the period for which you can view the graphed data by scrolling back in the Stats Graph window. The history can also be defined from the Resources menu in the Real-Time Stats Graph window.
16. Click the Plot Graph toggle button to display the statistics as a plot graph.

The Plot Graph displays each of your statistics as an
individual line associated with each linkset. Find the color for the El Paso-Amarillo linkset FISU count and then follow it on the graph. Each element will display in a different color for each statistic selected.
18. From the Resources Menu, click on Graph Resources option to display the Plot Graph Resources Window.

Selecting Show X Grids will display the vertical gridlines. Selecting Show Y Grids will show the horizontal gridlines. Select both to show a complete grid.
The width of the gridlines is determined by the Line Width field below the toggle buttons. Only integer values from 1 to 9 are allowed. Use the arrows to the right of the Line Width box to toggle the width up or down.
20. The Line Pattern box shows the pattern of the gridlines. Click on the box to show a pull-down menu of options for line patterns.
21. Select the format for the time displayed on the graph by clicking on the X Axis Time Format button. The options are Min:Sec or Hour:Min:Sec. Select Min:Sec.
22. Choose to show a legend by clicking on the Show Legend toggle button. The legend is shown below the graph.
23. Choose to show a border around the top and right sides of the graph by clicking on the Show Axis Bounding Box toggle button. Clicking on it again removes the border and shows only the X and Y axes. Leave the border on.
24. The Display Time Interval is the length of time in seconds for which data is displayed simultaneously in the graph window (the time duration from the left side to the right side of the window without scrolling back). Enter 60 seconds, and press
Return or click on Apply.
25. The history field is the length of time for which data is displayed in the scrollable region of the graph window (the total time duration if you scroll from the furthest point on the left to the furthest point on the right). The history field should display 0 hours and 45 minutes because you entered it in step 15.
