Performance Monitoring

• RX_COUNT - Words in frames received at the port

• TX_COUNT - Words in frames transmitted from the port

To enable end-to-end performance monitoring, you must install an end-to-end monitor on an F_Port

using the perfAddEEMonitor command, specifying the SID-DID pair (in hexadecimal). End-to-end

monitoring on N-ports is not supported in AG mode. Complete details of the perfAddEEMonitor

command parameters are provided in the Fabric OS Command Reference Manual.

NOTE

End-to-end monitors are not supported on logical EX, VE, VEX, Mirror, or FCoE ports.

For more information on end-to-end monitoring, including the following topics, refer to the

“End-to-end performance monitoring” section in the Fabric OS Administrator’s Guide:

• General feature information

• Fabric OS commands for end-to-end monitors

• The maximum number of end-to-end monitors per switch model

• Setting a mask for a monitor

• Deleting a monitor

Frame monitors

Frame monitors count the number of times a frame with a particular pattern is transmitted by a

port and generate alerts when thresholds are crossed. Frame monitoring is achieved by defining a

filter, or frame type, for a particular purpose. The frame type can be a standard type (for example,

an SCSI read command filter that counts the number of SCSI read commands that have been

transmitted by the port) or a frame type that you can customize for a particular use. For a complete

list of the standard, pre-defined frame types, see the fmMonitor command description in the Fabric

OS Command Reference Manual.

To enable frame monitoring, you must install a frame monitor on an F_Port or N_Port in the AG

switch using the fmMonitor command. Using options in this command, you can also perform the

following tasks:

• Create a new frame type.

• Delete a specified frame type.

• Delete the set of ports on which the specified frame type can be monitored.

• Add a set of ports for which a specific frame type can be monitored.

• Save a set of ports on which the specified frame type can be monitored.

• Show different frame types configured on the switch, as well as frame counters.

• Change properties for a particular frame type, such as thresholds and bit pattern.

• Clear a set of ports on which the specified frame type is monitored to the persistent

configuration.

Complete details of the fmMonitor command parameters are provided in the Fabric OS Command

Reference Manual.

The thConfig command can be used for advanced configuration of filter thresholds corresponding

to frame monitors. See the Fabric Watch Administrator’s Guide for more information about using

this command.
