Application Discovery 6.0 Software: User Guide

The degree of sharing among processes is unknown. For a given process, the shared memory
can be shared with every process on the system, only some processes on the system, only
some processes within the application, or with all of the processes within the application.
The 'right' answer for how to sum shared memory for processes depends in part on how
the individual administrator uses the information for planning. For example, is the
administrator thinking of adding an application instance to the host? Is he or she thinking
of moving an application instance to another host? Is the administrator thinking of moving
the entire application to another host?
To arrive at a usable deterministic answer, all the shared memory for each process is summed.
This conservative calculation should allow you to safely estimate resource usage for the
applications shown.
Understanding server resource consumption
Application Discovery consumes varying amounts of server resources as it goes about its work
of discovering application and system data for display and storage. To monitor this resource
usage, select the Admin/Config tab and then the AD Server tab.
On the AD Server tab screen, you can see a graphic display of Application Discovery memory
consumption plotted against discovery data for processes and packages.
Figure 2-4 Example of Application Discovery server memory consumption
The key to the graphic is as follows:
Memory usage by the Application Discovery server

Total number of processes found — matched and unmatched to known
templates or packages
Tot procs
Total number of processes found that have not been matched to known
templates or packages
Tot unmatched procs
Total number of expected packages according to initial survey.
