Working with Groups
It is a good idea to sort your network devices (i.e.,
servers, routers, switches, etc.) into some kind of hierarchical group (e.g. by
location, by department, by importance, by project) to make the list of devices
easier to administer. So a "group" is a collection of several "servers".

The beginning of a group is shown by horizontal bars in the
list of servers and sensors. The numbers in parenthesis show the number of good,
failed, or slow sensors (if applicable). You can click the minus button on the
right
to fold up the servers of
a group.
See Managing Groups, Servers, and
Sensors for more information on adding and editing groups.
