Introducing Advanced Performance Monitoring

• Fibre channel words that have been received by the port for the SID-DID pair
Filter-based Monitoring
Filter-based monitoring provides information about a filter’s hit count. Any pattern of values in the
first 64 bytes of the Fibre Channel frame can be measured. The counter increases each time a frame
is filtered through the corresponding port. Examples of port filter statistics that can be measured
are:
• SCSI Read, Write, or Read/Write commands
• IP vs. SCSI traffic comparison
Performance Monitoring with Web Tools
You can monitor performance using Web Tools, if a Web Tools license is also installed. The
enhanced Advanced Performance Monitoring features in Web Tools provide:
• Pre-defined reports for AL_PA, end-to-end, and filter-based performance monitoring.
• User-definable reports
• Performance canvas for application level or fabric level views
• Configuration editor (save, copy, edit, and remove multiple configurations)
• Persistent graphs across reboots (saves parameter data across reboots)
• Print capabilities
Predefined Performance Graphs
Predefined graphs are provided to simplify performance monitoring. A wide range of end-to-end
fabric, LUN, device, and port metrics are included.
Table 1-1 lists the predefined performance
graphs available with both basic and advanced performance monitoring. Figure 1-1 shows how to
access the list of predefined advanced performance monitoring graphs in Web Tools.
