27Fabric OS 5.0 features overview
Advanced Performance Monitoring
Advanced Performance Monitoring (APM) allows you to monitor the performance of networked
storage resources. This product helps reduce overprovisioning and enables SAN
performance tuning.
Advanced Performance Monitoring provides SAN performance monitoring through an
end-to-end monitoring system that provides the following:
• Increased end-to-end visibility into the fabric
• More accurate reporting for service-level agreements and charged access applications
• Shortened troubleshooting time
• Better capacity planning
• Increased productivity through preformatted and customized screens and reports
You can administer APM through the Fabric OS CLI, Advanced Web Tools, or Fabric Manager.
Using APM, you can perform the following activities:
• Measure the bandwidth consumed by individual routes (host-target pairs)
• Provide device performance measurements by port, Arbitrated Loop Physical Address
(AL_PA), and Logical Unit Number (LUN)
• Report cyclic redundancy check (CRC) error measurement statistics
• Measure HP ISL trunking performance and resource usage.
NOTE: ISL monitoring is set up on E_ports automatically in Fabric OS 4.x and later.
• Compare IP versus SCSI traffic on each port
• Produce a wide range of predefined reports
• Create customized user-defined reports
• Provide a performance history for each port
• Use the Fabric Manager application (version 4.x or later) to store performance data
persistently off the switch and maintain historical data for the performance of the switches
in your fabric
