17 Administering Advanced Performance Monitoring
(APM)
Based on Frame Filtering technology and a unique performance counter engine, Advanced Performance
Monitoring (APM) 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 InterSwitch Link (ISL) Trunking performance and resource usage
NOTE: Advanced Performance Monitoring is not supported on VE_Ports (virtual FC_Ports) and EX_Ports. If
you issue commands for any Advanced Performance Monitors on VE_Ports or EX_Ports you will receive
error messages. Refer to ”Using the FCIP Tunneling Service” on page 273 for more information about
VE_Ports.
Additional features are provided through Web Tools. For additional information, refer to Web Tools
Administrator’s Guide.
NOTE: The 4/16 SAN Switch, 4/8 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class BladeSystem,
Brocade 4Gb SAN Switch for HP c-Class BladeSystem, SAN Switch 4/32, SAN Switch 4/32B, 4/64 SAN
Switch, 400 MP Router, and 4/256 SAN Director switches do not display AL_PA measurements for
end-to-end monitors. CRC reports are accessed using Web Tools.
Also, AL_PA monitoring is not supported on NPIV configured ports.
