Novell SUSE LINUX ENTERPRISE DESKTOP 11 SP1 - 8-18-2010 VIRTUALIZATION WITH ZEN Manual page 96

9.5.2 Monitor Xen with xentop
Information is also available when only a standard terminal is available on no X envi-
ronment. The preferred tool to gather information in this case is xentop. Unfortunately,
this tool needs a rather broad terminal, else it inserts line breaks into the display.
xentop has several command keys that can give you more information about the
system that is monitored. Some of the more important are:
D
Change the delay between the refreshs of the screen
N
Also display network statistics. Note, that only standard configurations will be
displayed. If you use a special configuration like a routed network, no network will
be displayed at all.
B
Display the respective block devices and their cumulated usage count.
For more information about xentop see the manual page man 1 xentop.
9.5.3 More Helpful Tools
There are many different system tools that also help monitoring or debugging a running
SUSE Linux Enterprise system. Many of these are covered in the official SUSE Linux
Enterprise documentation. Especially useful for monitoring a virtualization environment
are the following tools:
ip
The command line utility ip may be used to monitor arbitrary network interfaces.
This is especially useful, if you did set up a network that is routed or applied a
masqueraded network. To monitor a network interface with the name alice.0,
run the following command:
watch ip -s link show alice.0
