Chapter 29, Performance Data
In the section “SAN historical performance data,” on page 1478, after the section “How to extract
performance statistics data from the database”, add the following section:
Performance statistics counters
Table 1 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 1).
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).
