Graph
The graph is real-time with constant updates according to the Sample Time. The results shift as the
new data is mapped on the graph. The Sample Time is displayed in the Graph Control area.
Legend
A list displaying the MIBs in the graph and their automatically assigned color-codes. Check/clear the
Show Legend checkbox to display or hide the graph legend.

Display Configuration

The graph in the display area can be manipulated into different configurations.

Graph Controls

This area describes the parameters used in generating the data for display in the graphs. They include
the following:
♦ Graph Type – Choose from various graphs types for data analysis. The available graph types
are; bar, area, stacking area, plot, scatter-plot, stacking-bar and pie.
♦ Data Buffer Size – How many polling sessions will remain in memory for viewed by scrolling.
Range is 5 to 100.
♦ Monitor Size – How many polling sessions are displayed without scrolling. Range is 1 to 100.
♦ Sample Time – How often the device or interface is polled (time interval, in seconds, between
polling sessions). Range is 3 to 3600 seconds.
♦ Presentation Units – How often the histogram is updated.
If the Presentation Units value is set to Sample Time, the graph is updated at the polling
rate specified in the Sample Time field.
If the Presentation Units is set to a value different from the Sample Time value, the
histogram is updated at the Presentation Units rate displaying the estimated polling
results. The graph is also updated with the true data at the Sample Time rate.
Set the Presentation Units to a value lower than the Sample Time in traffic-heavy
systems (where too frequent system polling is not recommended).
For example: if the Sample Time is set to 10 seconds and the Presentation Units to 1
second, the graph is refreshed every second with extrapolated data and every 10 seconds
with true data.
Close – Closes the graph window.
Show/Hide Control Panel – Hides the Display and Graph controls.
