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
page976.
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 8 6 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).
