Retrieval time increases when you are in a large fabric as there is more data to fetch from the switch(s).
• Processor speed of the system you are using may slow down the refresh rate.
• OS-Job Scheduling if you are using a host-system in the data center impacts the refresh rate
• JVM-Performance can contribute to causing interval differences between what is on-screen and
how long it is actually taking.
For these reasons, you might see that the time displayed in the port statistics tab isn’t refreshed as
expected. The counter time indicates only that “this statistics data is retrieved from the switch in this
time.” This is the reason the time field is updated along with the port statistics data after every refresh.
The lag in refresh rate is more evident in the iSCSI Target Gateway module.
Displaying Switches in the Fabric
If your fabric has more than one switch, you can launch Web Tools from one switch and then access
other switches.
You should not launch switches running Fabric OS v4.4.x or higher from a fabric tree displayed for a
pre-v4.4.x switch, as some features might be disabled.
To access the Switch Explorer for a particular switch
1. Launch Web Tools as described in “Launching Web Tools” on page 1-8 and log in to the switch
The Switch Explorer is displayed for the switch you logged in to. The Fabric Tree is expanded by
default when you first launch Web Tools.
2. If the Fabric Tree is not expanded, click the plus sign (+) in the Fabric Tree to view all the switches
in the fabric.
3. Click a switch in the Fabric Tree.
A separate browser window opens and displays the selected switch. (If the launch switch is running
a Fabric OS version earlier than v5.0.1, the selected switch displays in the same browser window.)
The graphic of the selected switch is displayed in the Switch View. Additional switch information
is displayed in the Switch Information View.
