Graph Timer Properties

The default graph file, GRAPH.wgg contains one graph object, "timer," which is determined by the Interval specified in the graph options. The timer shows the time elapsed between reported SNMP values (or SNMP "gets").

To change the timer's properties:

  1. Select the timer in the legend.
  2. From the Edit menu, select Item Properties.
    • Absolute values. When this is selected, graphs the reported values for the timer rather than graphing the change between the last reported value and the current value (which is the default method).
    • Rate per second. When this is selected, calculates the average change per second in the values reported for the SNMP object, and then graphs the result. To calculate this average, it takes the difference between the latest reported value and the previously reported value, then divides by the number of seconds between reported values. This is useful when the graph Interval is different than one second. You cannot use this option with the Absolute values option.
    • AutoScale. When this is selected, the graph scale for the timer is determined by the graphing utility. This is a relative scale that is calculated to make the graph fit into the vertical scale. If you turn off this option, the Scale option becomes active and you can enter a value to scale the graph.
    • Line width. Sets the width of the line that represents the timer on the graph. Select a width from the list box.
    • Color. Sets the color of the line that represents the timer on the graph. Select a color from the list box.
    • Scale. When AutoScale is cleared (not checked), you can enter a fixed value in this text box to determine the scale of the graph. You may want to try different values in this box until you find a scale that is useful.
