SAN Top Talker monitoring
43
You can create Top Talker monitors on selected devices. Use Top Talkers to display the connections
which are using the most bandwidth on the selected device or port. Top Talkers can be enabled on
the device or one of the F_Ports on the device. You can only use Top Talkers to view real-time
performance data.
You can have multiple Top Talker monitors configured at the same time. You can monitor up to 10
switches for fabric mode Top Talkers and 32 ports and 10 switches for F_Port Top Talkers;
however, you can only monitor one device or port for each Top Talker you configure.
NOTE
If the Fabric OS device is configured for Fibre Channel routing (FCR), you can only configure a Top
Talker monitor on the following devices:
- 16 Gbps Backbone Chassis with a FC 16 Gbps 32-port or 48-port blade
- 16 Gbps 48-port switch
Configuring a fabric mode Top Talker monitor
Procedures in this section pertain to configuring the legacy Top Talkers feature instead of using
Flow Vision.
For systems using Fabric OS version 7.2 or later, when you select a device or device port, and then
select Monitor > Performance > Top Talkers, a message displays that you can use Flow Vision to
provide Top Talkers monitoring. You have these options:
• To use Flow Vision, delete existing monitors, then use the Add Flow Definition dialog box to
define an initiator and target port pair for monitoring. Refer to
Chapter 44, “Flow Vision” for
more information.
• Clicking OK opens the legacy Top Talkers dialog box. To use the legacy Top Talkers feature, you
must deactivate existing flows defined for the switch for Flow Vision.
Here are some important notes for using this feature.
NOTE
A fabric mode Top Talker and an end-to-end monitor cannot be configured on the same fabric. You
must delete the end-to-end monitor before you configure the fabric mode Top Talker.
NOTE
A fabric mode Top Talker and an F_Port mode Top Talker cannot be configured on the same fabric.
You must delete the F_Port mode Top Talker before you configure the fabric mode Top Talker.
NOTE
You cannot enable Top Talkers for a single-switch fabric.
To configure a fabric mode Top Talker monitor on systems using Fabric OS before v7.2, complete
the following steps.
1. Select the fabric on which you want to monitor Top Talker data.
NOTE
On the 8 Gbps 8-FC port, 10 GbE 24-DCB port Switch, Top Talkers is only supported on the
8 Gbps FC Ports.
2. Select Monitor > Performance > Top Talkers.
