Monitoring performance using Web Tools
9
The advanced monitoring graphs give more detailed performance information to help you manage
your fabric. You can access the basic monitoring graphs on all switches; advanced monitoring
graphs are available only on switches that have a Brocade Advanced Performance Monitoring
license activated.
The Brocade 48000 with an FC4-18i and the Brocade 7500 include physical FC ports, logical FC
ports, and GbE ports. The Brocade 48000 with a or FC4-16IP blade includes physical FC ports and
GbE ports. Not all of the performance monitoring graphs support the logical FC ports and GbE
ports.
TABLE 6 Basic performance graphs
Graph Type Displays
Port Throughput The performance of a port, in bytes per second, for frames received and
transmitted.
Switch Aggregate Throughput The aggregate performance of all ports on a switch.
Blade Aggregate Throughput The aggregate performance of all ports on a port card. This graph is
available only for the Brocade 24000 and 48000 directors.
Switch Throughput Utilization The port throughput, in Gbit/sec, at the time the sample is taken. For the
Brocade 24000 and 48000 directors, this graph displays the throughput for
each slot. You can customize this graph to display information for particular
ports.
Port Error CRC errors for a given port.
Switch Percent Utilization The percentage utilization for each port in a switch. For the Brocade 24000
and 48000 directors, this graph displays the percent utilization for each
slot. You can customize this graph to display information for particular ports.
Port Snapshot Error The CRC error count between sampling periods for all the ports on a switch.
For the Brocade 24000 and 48000 directors, this graph displays the CRC
error rate for each slot. You can customize this graph to display information
for particular ports.
TABLE 7 Advanced performance monitoring graphs
Graph Type Displays
SID/DID Performance The traffic between the SID-DID pair on the switch being managed. For
more information, see “Creating SID-DID Performance Graphs” on
page 129.
SCSI vs. IP Traffic The percentage of SCSI versus IP frame traffic on each individual port. For
more information, see “Creating an SCSI vs. IP Traffic Graph” on page 130.
AL_PA Errors CRC errors for a given port and a given AL_PA. For more information, see
“Creating AL_PA Error Graphs” on page 132.
SCSI Commands by port and LUN
(R, W, R/W)
The total number of read/write commands on a given port to a specific LUN.
For more information, see “Creating SCSI Command Graphs” on page 131.
