You can also use Fabric Watch to configure thresholds corresponding to specific frame monitors
Refer to the Fabric Watch Administrator's Guide for details.
End to End monitors
End to End monitors measure the traffic between a host and target pair by counting 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
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:
