Monitoring; End-To-End Performance Monitoring; Maximum Number Of Ee Monitors - HP SN3000B Administrator's Manual

Access Gateway considerations for Advanced Performance Monitoring
EE monitors and frame monitors are supported on switches in Access Gateway mode. Top Talker
monitors are not supported on these switches.
EE monitors must be installed on F_Ports. Frame monitors can be installed on F_Ports or N_Ports.
See the Access Gateway Administrator's Guide for additional information.

End-to-end performance monitoring

Use end-to-end (EE) monitoring when you want to monitor throughput between a pair of devices.
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.
To enable EE performance monitoring, you must configure an EE monitor on a port, specifying the
SID-DID pair (in hexadecimal). The monitor counts only those frames with matching SID and DID.
Each SID or DID has the following three fields:
•
•
•
For example, the SID 0x118a0f denotes DD 0x11, AA 0x8a, and AL_PA 0x0f.
An EE monitor includes these counts:
•
•

Maximum number of EE monitors

The maximum number of end-to-end monitors supported varies depending on the switch model:
•
•
The number of interswitch links (ISLs) configured on the switch affects the amount of resources
available for end-to-end monitors.
Virtual Fabrics considerations: If Virtual Fabrics is enabled, the Brocade DCX, DCX-4S, DCX 8510
and 5300 models allow up to 256 end-to-end monitors on one logical switch. The Brocade 5100,
6510, and VA-40FC allow up to 337 end-to-end monitors on one logical switch.

RX_COUNT - words in frames received at the port
For frames received at the port with the EE monitor installed, the RX_COUNT is updated if the
frame SID is the same as the SID in the monitor and the frame DID is the same as the DID in
the monitor.
TX_COUNT - words in frames transmitted from the port
For frames transmitted from the port with the EE monitor installed, TX_COUNT is updated if the
frame DID is the same as the SID in the monitor and the frame SID is the same as the DID in
the monitor.
The Brocade DCX, DCX-4S, DCX 8510, 5100, 6505, 6510, 8000, VA-40FC, and Brocade
Encryption Switch models allow up to 1024 end-to-end monitors shared by all ports in the
same ASIC.
The Brocade 300, 5300, 5410, 5424, 5450, 5460, 5470, 5480, and 7800 models allow up to
768 end-to-end monitors shared by all ports in the same ASIC.
