SNMP Graph Options

Use the Graph Options dialog box to set the layout of the Graph window, the interval (or frequency) for recording values for the SNMP objects, and whether you want to record the data to a file.

• Legend. When selected, the Legend appears at the bottom of the graph window. The Legend displays each graphed SNMP object and its associated device, as well as any accumulator items.
• Interval (seconds). Sets the time interval at which the graph records values.
• Vertical (y-axis). When Grid is selected, it displays lines across the graph to help you read the y-axis values. When Labels is selected, the values are displayed along the y-axis. The Maximum determines the highest value on the y-axis scale, as well as the internal values. This value cannot exceed 1500.
• Horizontal (x-axis). When Grid is selected, it displays lines across the graph to help you read the x-axis values. When Labels is selected, the values are displayed along to the x- axis. The Maximum determines the highest value on the x-axis, as well as the internal values. This value cannot exceed 1500.
• Save Window Location. When selected, it saves the position of the Graph Window so that it always opens in the same location on your screen.
• Record data to. If you want to save graph data, select this box and enter a file name. The file is saved in the WhatsUp directory. The file format is tab-delimited and can be imported to a spreadsheet application.
• Append new data to datafile if it already exists. By default, this is selected. Whenever the graph is running, the SNMP values will be appended to the existing file. If this is NOT selected, the new data will replace the existing file.

File Format

Date [tab] time [tab] first item value [tab] second item value [tab] ...

Note: The file format does not actually contain any spaces. They are only added here to make reading easier.

For example, a graph with four items would show the date and time plus the four values recorded at that time. The heading shows the IP address and SNMP object identifier for each graph item.
