Tool Bar

The Tool Bar has the following icons:

•    — Hides the Display and Graph controls.

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 are 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.

Display Controls

This area controls what is displayed on the screen.

Alarm Definitions

Displays the variable alarm characteristics.
