Performance statistics counters
Table 142
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 142
).
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).
