End-to-end performance monitoring
17
• ISL monitors measure the traffic transmitted through an InterSwitch Link (ISL) to different
destination domains.
• Top Talkers monitors measure the flows that are major consumers of bandwidth on a switch or
port.
The type of monitors supported depends on the switch model, as shown in Table 79.
NOTE
Advanced Performance Monitoring is not supported on VE_Ports and EX_Ports. If you issue
commands for any Advanced Performance Monitors on VE_Ports or EX_Ports you will receive error
messages.
Virtual Fabrics considerations for Advanced Performance Monitoring
In a fabric with Virtual Fabrics enabled, the number of logical switches that can be configured with
monitors is restricted. Table 80 lists the platforms that support logical switches and, for each
platform, the maximum number of logical switches that can support performance monitors.
Each logical switch can have its own set of performance monitors. The installation of monitors is
restricted to the ports that are present in the respective logical switch.
End-to-end performance monitoring
End-to-end performance monitoring counts the number of words in Fibre Channel frames for a
specified Source ID (SID) and Destination ID (DID) pair. An end-to-end performance monitor
includes these counts:
• RX_COUNT - words in frames received at the port
• TX_COUNT - words in frames transmitted from the port
