Monitoring performance using Web Tools
9
Graphs within the Performance Monitoring window are updated every 30 seconds. When you first
display the graph or if you modify the graph (such as to add additional ports), you might have to
wait up to 30 seconds before the new values are shown.
When you have multiple graphs open in the Performance Monitoring window, you can:
• Click Window> Tile to view all graphs at once, tiled in the Performance Monitoring window.
• Select Window> Cascade to view one graph at a time.
• Select Window> Close All to close all open Performance Monitor graphs in the Performance
Monitoring window.
In addition, the Window menu lists all open graphs. You can click Window, and then select a graph
name to view that graph.
Admin Domain considerations:
• If you are not the switch owner, you will see the following ports:
• E_ports, including EX_Ports
• directly owned ports
• indirect ports
• You can use the Advanced Performance Monitoring feature only in AD255 or in AD0 if there are
no other user-defined Admin Domains. Otherwise, access to Advanced Monitoring features in
the Performance Graphs menu will be unavailable.
• It is recommended that you define a user with a switchadmin role and give that user access to
AD255 for the purpose of data collecting using the Advanced Performance Monitor.
Predefined performance graphs
Web Tools predefines basic graph types, to simplify performance monitoring. A wide range of
end-to-end fabric, LUN, device, and port metrics graphs are included.
Table 6 lists the basic monitoring graphs available. Table 7 on page 121 lists the advanced
monitoring graphs.
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.
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 48000 and Brocade DCX Director.
Switch Throughput Utilization The port throughput, in Gbit/sec, at the time the sample is taken. For the
Brocade 48000 and Brocade DCX Director, 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.
