7.2.6 Displaying Fibre Channel switch performance information

From the device tree view in the Performance Management window, select and right-click the port number of the Fibre Channel switch whose performance information you want to display, and then select [Show Performance Graph] from the resulting pop-up menu.

The dialog shown below appears. In the dialog, select the items to be displayed.

Items

Explanation

Time Axis

Select the time interval for a graph that you want to display. Select one hour, one day, or one week.
Refer to "7.1.2 Performance Graph Window Types" for details.

Date Specification

Specify the date and time to be displayed the center of the graph. The current time is displayed. You may select the date and time of a graph that you want to display. A period of up to 7 days can be specified.

Throughput

Displays a data transfer rate (MB/S). Here, select an information type. Select one of the following three: (1) displaying the graphic window for the transmitting-side performance of a port, (2) displaying the graphic window for the receiving-side performance, and (3) displaying one graphic window where both transmission and reception performances are displayed at the same time. The transmission and reception performances can be selected at the same time but, if the combined transmission-reception performances are selected, neither the individual transmission performance nor the reception performance can be selected.

Error

Displays the graph of a CRC error count that occurs in the port.

The window shown below displays a result of selections in the above dialog. One-hour Graph windows of send throughput and receive throughput are displayed. Using the graphs, you can determine the operating status of the port. See "B.10.5 Graph window functions".

To display performance information of multiple ports at the same time, click multiple ports in the tree while holding down the [Ctrl] or [Shift] key, and then right-click a selected port to display a graph.

In this case, "Open Window for Every Port" is added to the dialog displayed immediately before a graph is displayed. If you check the check box, one window for each port opens.

If you do not check the check box, you can select "Total of Throughput" in the dialog. If you select it, the total values of the ports are displayed in a graph. Otherwise, values of each port are displayed in the same graph window. Incidentally, if "Send/Receive" is selected, "Total of Throughput" must be selected.

The window shown below is an example where "Open a window for each port" and "Total of Throughput" are not selected. To check the correspondence between ports and lines in the graph in the window, select a button for a line in the graph. In this example, port 14 is frequently used.
