•Destination Port Type - The port type through which the selected device is connected to the destination device.

•Additional Measures columns - Displays each measure selected in the Measures list and Additional Measures area.

•Measures columns - A column for each selected measure in the Measures list or Additional Measures area.

Exporting real-time performance data

To export real-time performance data, complete the following steps.

1.Generate a performance graph.

To generate a performance graph, refer to “Generating a real-time performance graph” on page 976.

2.Right-click anywhere in the graph table and select Export Table. The Save table to a tab delimited file dialog box displays.

3.Browse to the file location where you want to save the performance data.

4.Enter a name for the file and click Save.

Performance statistics counters

Table 86 details the formulas used to calculate performance statistics based on counter type and protocol.

To calculate FC, GE, FCIP and TE port statistics, the Management application uses SNMP to query the respective object identifiers (OID) (listed in Table 86).

To calculate HBA and CNA statistics, the Management application uses APIs provided by HCM.

To calculate end-to-end monitor (EE monitor) statistics, the Management application uses HTTP to obtain the TX, RX, and CRC error values.

The polling interval for historical graphs is 5 minutes. The polling interval for real-time graphs is based on the granularity value (configured in the Real Time Graph dialog box).

TABLE 86	Performance statistic counters
Counter name	Type	Protocol	Source OID value	Formula
TX	FC	SNMP	.1.3.6.1.3.94.4.5.1.6	TX = (delta value1 / (1000 * 1000)) /
				(polling interval2)
RX	FC	SNMP	.1.3.6.1.3.94.4.5.1.7	RX = (delta value1 / (1000 * 1000)) /
				(polling interval2)
TX	GE	SNMP	.1.3.6.1.2.1.31.1.1.1.10	TX = (delta value1 / (1000 * 1000)) /
				(polling interval2)
RX	GE	SNMP	.1.3.6.1.2.1.31.1.1.1.6	RX = (delta value1 / (1000 * 1000)) /
				(polling interval2)
TX	FCIP	SNMP	.1.3.6.1.2.1.31.1.1.1.10	TX = (delta value1 / (1000 * 1000)) /
				(polling interval2)
