Administering Advanced Performance Monitoring (Apm) - HP AA979A - StorageWorks SAN Switch 2/8V Administrator's Manual

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
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, SAN Switch 4/32, 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.
