Multiple Device Threshold Graphs

The Multi Threshold Graph is designed to give the user a view of one threshold type for many devices at the same time. A Multiple Device Thresholds Video is also available.

Selection

The main method of selection is from the menu of a device. In this case all the devices connected to and below this device relative to the IntraVUE host computer are displayed together.

An alternate method of selection is to select several devices in the main user interface and then the device menu will allow you to view just the selected devices in the Multi Threshold Graph. (starting in version 2.1)

A third method is available from within the Event log and depends on how events are selected.

Data

The data available for Mutil Threshold Graphs is exactly the same as the Threshold Line graphs available by right clicking on any connecting line.

The data includes:

Graph Elements

The small image above contains numbered markers for each of the major graph elemets.

The red 1 box is next to the Graph Title which includes the specific threshold currently displayed and the time period of the data.

The scale of the data values is near the red 2. The scale changes each time new data is graphed and is redrawn so the the maximum graph value is near the top of the graph.

The red 3 is near the time values for the graph. When displaying 3 hour data the values will be the normal clock time. When displaying data for longer time periods there may be up to three lines of time information. For instance, 12 month data will indicate the year, month, and day.

Note that the available data will fill the graph from left to right. If there is only a weeks worth of data in the database and you select the 12 month view, the available data will fill the x axis.

There will typically be an indication of the start and ending date/times in this area.

The red 4 shows where the graph legend is. Each device will have a color assigned to it. If you have problems telling which line belongs to which device there is hover text near graph points as well as a zoom feature (see below).

User Selection Options

The Time Interval drop down list allows you to select between 3 hours of data and 12 months of data. If data is not available for the entire period the time scale axis will be limited to the available data. If you were to choose the 12 month option and IntraVUE had only scanned for one hour, no data will be available.

The Max Devices To Graph edit box allows you to limit the number of devices that will appear in the graph. The limit is based on worst case data. If 20 or less devices are graphed, a legend will be displayed under the graph. Set the Max Devices to Graph to 21 or more and NO legend will be displayed.

You can select whether the graph shows Average Values for the data being graphed or Peak Values. As data becomes older it is stored in fields that represent more information. One minute becomes 10 minute, becomes 2 hour, etc. Intravue stores both the average of these periods as well as the maximum value for these periods. This prevents a spike in a single minute from being lost when it eventually becomes 1 day data.

The Threshold to Graph radio buttons allow you to select amoung the four typs of graphs

The Nodes to Graph radio buttons allow you to filter data for only switches, only devices, all devices, or if the current device is a switch, only the ports of the current switch. [Note this last option is not available in the pre-release]

The Graph Now button gets new data from the IntraVUE database and displays the results. Note: The graph does not update after changing selections, it only updates when this button is selected.

Hover Text

When the mouse is positioned near a graph POINT, not the line, hover text will indicate the IP Address of the device and the time of the value.

Zooming in

You can zoom in on any portion of the graph by dragging the mouse with the left mouse button. To zoom in you must drag the mouse to the right and downward. As you drag you will see the outline of the zoom area. When you release the graph will be zoomed.

You may zoom in as many times as you like.

Zooming out

When you are ready to zoom out, simply drag the mouse in any direction except right and down.
