perfAddEEMonitor
Adds an end-to-end monitor to a port.
SYNOPSIS perfaddeemonitor [slot/]port SourceID DestID [-force]
DESCRIPTION Use this command to add an end-to-end performance monitor to a port. The performance monitor counts
the number of words received, number of words transmitted, and number of CRC errors detected using
either of the following conditions:
•
For frames received at the port, the frame SID is the same as SourceID and frame DID is the same
as DestID; both RX_COUNT and CRC_COUNT are updated accordingly.
•
For frames transmitted from the port, the frame DID is the same as SourceID and frame SID is the
same as DestID; both TX_COUNT and CRC_COUNT are updated accordingly.
To monitor traffic from host A to device B, add a monitor on port 2, specifying 0x050200 as the SID and
0x010100 as the DID. The RX count equals the number of words from host A to device B, whereas the
TX count equals the number of words from device B to host A. The CRC count equals the total number of
CRC errors for both directions. Adding a monitor on port 1, specifying 0x010100 as SID and 0X050200
as the DID has a similar effect, except the RX and TX counts are interchanged.
To monitor traffic between one Initiator host and one target storage device connected to an Encryption
Switch, you must add two monitors because of the manner in which the real initiators or targets transfer
data to VIs and VTs. The first monitor would be added between the initiator SID and the virtual initiator
DID, and the second monitor would be set up between virtual target SID and the target DID. Refer to the
Examples section for details.
Identical monitors cannot be added to the same port. Two monitors are considered identical if they have
the same SID and DID values after applying the end-to-end mask.
Execution of this command displays a monitor number, which can be used to manipulate performance
monitors.
Because of a hardware limitation on Brocade devices, the following types of monitors cannot coexist on
the same ASIC chip:
•
If an end-to-end monitor is installed on a port in a given ASIC, you cannot install an ingress or
egress Top Talker monitor on another port on the same ASIC.
•
If an ingress Top Talker monitor is installed on a port in a given ASIC, you cannot install an egress
Top Talker monitor or an end-to-end monitor on another port of the same ASIC.
•
If an egress Top Talker monitor is installed on a port in a given ASIC, you cannot install an ingress
Top Talker monitor or an end-to-end monitor on another port of the same ASIC.
You can use the -force option to override these limitations and install incompatible monitors on ports of
the same ASIC. However, if you choose to do so, be aware that the statistics will not be accurate.
NOTES This command requires an Advanced Performance Monitoring license.
This command is not supported on virtual FC ports (VE/VEX_Port), EX_Port, M (Mirror) ports, and GbE
ports.
On 8Gb (Condor 2-based) platforms, End-to-End monitors are supported only on F_Ports. On 16Gb
(Condor 3-based) platforms, End-to-End monitor are supported on both F_Ports and E_Ports. When
installing an end-to-end monitor on an E_Port, be sure to install the SID and DID in the ingress direction.
End-to-end monitors are non-persistent and will be removed when you reboot the system or disable the
port. To make the monitors persistent, issue the perfCfgSave command before you perform operations
that causes the port to go offline. Issue the perfCfgRestore command after the port comes back up.
