monitoring
This chapter contains procedures for the HP Advanced Performance Monitoring licensed feature and
contains the following sections:
• Displaying and clearing the CRC error count, page 145
• Monitoring end-to-end performance, page 145
• Monitoring filter-based performance, page 149
• Monitoring ISL performance, page 152
• Monitoring trunks, page 152
• Displaying monitor counters, page 153
• Clearing monitor counters, page 155
• Saving and restoring monitor configurations, page 156
• Collecting performance data, page 156
Based on HP Frame Filtering technology and a unique performance counter engine, Advanced
Performance Monitoring is a comprehensive tool for monitoring the performance of networked storage
resources. It supports direct-attach, loop, and switched fabric Fibre Channel SAN topologies by:
• Monitoring transaction performance from source to destination
• Reporting cyclic redundancy check (CRC) error measurement statistics
• Measuring HP Inter-Switch Link (ISL) Trunking performance and resource usage
Further features are provided through HP Advanced Web Tools:
• Measuring device performance by port, arbitrated loop physical address (AL_PA), and logical unit
number (LUN)
• Comparing IP versus SCSI traffic on each port
• Providing a library of predefined graphs
NOTE: The SAN Switch 4/32 running Fabric OS v4.4.0 does not display AL_PA measurements for
end-to-end monitors. It provides port CRC reports through Advanced Web Tools.
Table 23 lists commands associated with Advanced Performance Monitoring. For detailed information on
these commands, refer to the HP StorageWorks Fabric OS 4.x command reference guide.
