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.
