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 accomodate 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.
