A call graph can potentially contain hundreds of methods. You can exclude packages (Java) or namespaces (.NET) with classes that you do not want to monitor.

For Java, some packages are excluded by default. These are visible in the Excluded Packages list. The packages that are excluded by default cannot be removed. However, you can include a particular sub-package from an excluded package.

You can customize call graph instrumentation from the call graph instrumentation page. From there, choose from these configuration options:

• Use the Add Custom Package Exclude (Java) or Add Custom Namespace Exclude (.NET) configuration options to exclude specific packages or namespaces from call graphs.
• Use the Add Always Show Package/Class (Java) or Add Always Show Namespace/Class (.NET) configuration options to have a package or namespace always shown in call graphs.

When the Controller constructs a call graph it uses excluded packages and included sub packages to determine which calls to include. However, the Controller includes some calls even if they are listed among the excluded packages. For example, web service calls.
