Fabric OS 6.2 administrator guide 407
You can monitor end-to-end performance using the perfMonitorShow command, as described in
”Displaying monitor counters” on page 418. You can clear end-to-end counters using the
perfMonitorClear command, as described in ”Clearing monitor counters” on page 420.
End-to-end monitors
The maximum number of end-to-end monitors supported varies depending on the switch model:
• The following products allow up to 256 end-to-end monitors shared by all ports in the same ASIC chop:
•HP StorageWorks SAN Switch 4/32
• HP StorageWorks 4/64 SAN Switch
•HP StorageWorks SAN Switch 4/32B
• HP StorageWorks 400 Multi-Protocol Router
• HP StorageWorks 4/256 SAN
• The following models allow up to 1024 end-to-end monitors shared by all ports in the same ASIC chip:
• HP StorageWorks DC SAN Backbone Director
• HP StorageWorks DC04 SAN Director Switch
• HP StorageWorks 8/40 SAN Switch
• The following switches allow up to 768 end-to-end monitors shared by all ports in the same ASIC chip:
• HP StorageWorks 8/8 SAN Switch
• HP StorageWorks 8/24 SAN Switche
• HP StorageWorks 8/80 SAN Switch
• The HP StorageWorks 4/8 and 4/16 SAN Switches allow up to 96 end-to-end monitors.
The number of interswitch links configured on the switch affects the amount of resources available for
end-to-end monitors.
Virtual Fabrics considerations: If Virtual Fabrics is enabled, the following switches allow up to 337
end-to-end monitors on one Logical Switch:
• HP StorageWorks DC SAN Backbone Director
• HP StorageWorks DC04 SAN Director Switch
• HP StorageWorks 8/40 SAN Switch
The
HP StorageWorks 4/48 SAN Director Blade allows end-to-end monitors on all 48 ports.
For the HP StorageWorks B-Series iSCSI Director Blade, end-to-end monitors are supported on the FC ports
(ports 0 through 7), but not on the GbE ports.
You cannot add end-to-end monitors to interswitch links. Identical end-to-end monitors cannot be added to
the same port. Two end-to-end monitors are considered identical if they have the same SID and DID values
after applying the end-to-end mask.
The monitor count is qualified using either of the following conditions:
• For frames received at the port with the end-to-end monitor installed, the frame SID is the same as
SourceID and the frame DID is the same as DestID. The RX_COUNT updated accordingly.
• For frames transmitted from the port with the end-to-end monitor installed, the frame DID is the same as
SourceID and the frame SID is the same as DestID. The TX_COUNT updated accordingly.
NOTE: The relationship between the area ID for a port and the port number depends on the PID format
used by the fabric. See Appendix A, ”Configuring the PID format” on page 523 for more information.
Adding end-to-end monitors
1. Connect to the switch and log in as admin.
2. Enter the following command:
perfaddeemonitor [slotnumber/]portnumber sourceID destID
