Split Second Graph: CPU

This workspace report displays real-time CPU utilization for all CPU's on a SNMP enabled device. The device must have SNMP credentials specified in Device Properties > Credentials. This report queries the specified device for a list of all CPU's and then polls and graphs each of them for the duration that the report is loaded in the Web browser.

Note: When viewing information for devices running Microsoft Windows, information gathered via WMI is displayed in real time. Information gathered by SNMP, however, may reflect a delay of one minute or more. This delay is caused by a limitation in how often Microsoft Windows updates SNMP values.

To configure this workspace report in WhatsUp Gold:

1. In the title bar of the workspace report pane, select Menu > Configure. The Configure Report dialog appears.
2. Enter or select the appropriate information in the following fields.
   • Report name. Enter a title for the workspace report. This name appears in the title bar of the workspace report's pane.
   • Device. Select a device for the report by clicking the browse (...) button.
   • Width. Specify how wide, in pixels, the graph or chart should appear.
   • Height. Specify how tall, in pixels, the graph or chart should appear.
   • Vertical Axis Scale. Select how you want the vertical axis, or Y axis, of this graph to display.
     • Auto Scale adjusts the axis value based on the minimum and maximum values of the data being displayed.
     • Fixed Scale shows the data on the scale you enter in the Min and Max boxes.

   Tip: Auto scale is the best option when the minimum and maximum chart values are unknown.

   Graph Type. Select the type of graph you would like to display. To learn about the various types of graphs available, please see Graph Types.

   • Trend Type. Select the type of trend line you want to see on the report. This line shows the average value of data for the duration the graph is displayed in the Web browser. Choose None, Line, or Curve.
   • Dimensions. Select the dimension in which you would like the graph to display. Select 3D or 2D to change the dimensions of the lines/bars in your charts.
   • Refresh interval (seconds). Enter an amount of time (in seconds) for how often you would like the graph to refresh. Essentially, when the graph refreshes, it is polling for more data and then displaying that new data.

   Note: The faster the refresh interval, the more granular the chart data will be. Slower poll intervals will result in data that is more normalized and will have less detail.

   • Data interval (seconds). Enter an amount of time (in seconds) for how long you would like the data in the graph to be displayed. Think of this as the X axis for the graph.

   Note: Specifying larger values for this setting is allowed, but may adversely affect the refresh interval for a graph. The optimum value is determined by the memory and speed of your Web server.
