Legacy performance monitoring features
Instead of Flow Monitor, you can use the legacy end-to-end and frame monitoring features available
through Advanced Performance Monitoring (APM). These legacy features are available on platforms
using Fabric OS 7.2 and earlier. The following licenses must be appropriately installed on the AG
switch to use the end-to-end and frame monitors:
• APM
• Fabric Watch
Use the following Fabric OS commands used to manage APM in switch mode to manage end to end
and frame monitoring in AG mode. Refer to the Fabric OS Command Reference Manual and Fabric
OS Administrator’s Guide for details.
• perfAddEEMonitor
• perfMonitorClear
• perfMonitorShow --class EE <port#>
• perfResourceShow
• perfCfgSave
• perfCfgClear
• perfCfgRestore
• fmmonitor
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 :

• 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
