How computer and group views are displayed
Chapter 1 Installing Perceive 61
On the Configure Tomcat for Perceive page during installation, make sure you type
unique port numbers for the Tomcat Web Server port and the Tomcat Java Server
port. If you are using PATROL Web Central, make sure that these port numbers are
different from those specified during the PATROL Web Central installation.
If you want to change port numbers after installation, change the
<installdir>/CWA/jakarta-tomcat-4.0.3/conf/server.xml file. To modify the Tomcat Web
Server port, search for the
non-SSL HTTP/1.1 Connector. To modify the Tomcat Java
Server port, search for the
AJP 1.3 Connector.
How computer and group views are displayed
After you install Perceive, the administrator must log in to Perceive and activate data
sources. Perceive then begins querying for data based on your specified
configuration. Perceive searches for computers on either a local UDR data repository,
a Visualizer database, or an existing policy file (on Windows systems) or domain file
(on UNIX systems), and displays those computers in logical groupings.
Perceive is view-driven, meaning the actions you perform (and the resultant display)
are based on whether you select computer views or group views in Perceive.
Based on the data Perceive displays, computers and groups of computers are
organized, and an interval of data is selected for viewing. These groupings are
reflected in the view categories that are built on the scope pane of the Perceive
display.
Groups are defined by the administrator (see “Creating, deleting, or renaming
groups” on page 150). Until the administrator creates groups, you can search for
computers to create a temporary search group (see “Finding computers” on page 76).
To maximize your return on investment, BMC Software developed and included a
minimum set of views to provide you with the most common use cases, such as
checking the status of a system, or verifying an I/O process investigation. These
views are based on a set of performance metrics and metric groups common to both
UNIX and Windows platforms.
Computers are selected based on whether a single computer or multiple computers
have been selected. The Group and Computer menus display what is determined
based on that selection, as detailed in the following sections.
Group views
Group views are organized based on the following situations.
