Introducing Xgig Performance Monitor

Xgig Performance Monitor is one of four applications in the Xgig Analyzer software suite.  It is a
versatile monitoring tool which shows performance and error statistics on all analyzer ports being
monitored.  Xgig Performance Monitor consists of views that provide a quick snapshot of the
current running state of the links being analyzed, as well as total statistics over time.  The views
are:

•

Chart View

Presents a view of the port and link information in a line graph with a historical view over
time. A

Total

line graph is also available if applicable.

•

List View

Brings up a set of table views with monitor data for each port or link. The row for a link
displays the sum of all values of each port in the link. The

Total

row shows the sum of values

for the chassis. The current view is selected from a tab at the bottom. Table views include data
transfer rate in megabytes, data transfer rates in kiloframes, utilization percentage, frame
statistics, frame errors, SAS/SATA error counters, PCIe errors, and physical errors.

•

Meter View

Presents the current transfer rate and a metered representation of the transfer rate.

•

LED View

Indicates the current status of all ports.

•

Summary of Status LEDs (LED Summary View)

Indicates the summary status of all ports. The number of ports that are in a particular state is
indicated with the status type.

Use Xgig Performance Monitor to monitor performance of each channel and detect errors. You
can vary the update rate to suit your measurement.

You can set the protocol of the port (Fibre Channel, GigE, SAS/SATA, or PCIe) from the

Select

Ports to Monitor

dialog box in Performance Monitor. You can also set the link speed and the

signal regeneration (analog passthrough, analog passthrough multiplexed, digital retime) from the

Hardware > Port Settings

menu of Xgig Performance Monitor.

If you exit and restart Performance Monitor, changes to the position and placement of all view
windows are preserved. It is recommended that you have no more than two instances of
Performance Monitor running per domain.
