6.3.1 Chart
In the left half of the window is the chart showing the values of the selected variables.
The vertical (Y) axis shows the values and the horizontal (X) axis shows the variable
name or number. You can select whether to display the name or the number in Option >
Option > Other.
Each variable is shown with a different color. The colors of the variables are displayed
between the chart and the variable table.
By placing the cursor on a bar, you can see the exact value of the variable.
6.3.2 MIB Variable Table
The right half of the window is the table of variables suitable for graph display. Each entry
has a checkbox. Only checked variables are shown on the chart.
Assume that you selected four variables to display. If one of the variables has a very large
value, for instance 1000000, and the other variables have much lower values, for instance
around 100, the vertical axis is automatically scaled to accommodate the largest variable.
In this situation, you can see the largest variable only because the scale of the vertical axis
is very large. To see the smaller variables, uncheck the largest variable temporarily.
Note - SNMPv3: Depending on the READ VIEW access settings of the User Account Name used,
there is a possibility that some MIB variables will not be displayed in this table.
6.3.3 Select All Button
: checks all variables. Clicking this button causes all variables to be plotted on the chart.
6.3.4 Clear Button
: unchecks all variables.
6.3.5 Reverse Button
: flips the states of all checkboxes, that is, unchecks all variables currently selected
and checks all variables currently not selected.
Note - Displaying many variables at the same time imposes a load on system resources.
If you encounter delay or reduced system performance, reduce the number of variables
displayed, or increase the polling interval. To reduce the number of variables, uncheck some
variables in the MIB variable table. To increase the polling interval, click the Options tab and
change the Polling Interval.
