Application classes
An application in PATROL is any resource used or running on a computer. The Knowledge Module for Windows Servers has a basic set of applications that monitor events such as CPU, logical disk, and memory usage. Each running copy of an application discovered by PATROL is called an instance of the particular application class. Each application instance is represented by an icon in the COMPUTER window. For more information, see Application-classes-and-icons.
Application discovery
PATROL discovers applications using instructions provided by the Knowledge Module for Windows (KM). The instructions provided by the KM include application discovery rules that you have defined.
When PATROL discovers an application, it represents the application with an icon either in the icon window for the monitored computer on which it runs or in an application window specified for all application instances of that class.
You can add a new application class to PATROL so that it will find all future instances of that application running on monitored computers.
PATROL periodically runs application discovery to discover new applications and to verify that previously discovered applications and files are still there. If an application or file previously discovered is not found, PATROL triggers an alert, either audible or visual, for the missing resource.
Application discovery rules
Application discovery rules are defined using either:
- Simple discovery
- PATROL Script Language (PSL) discovery
Simple discovery uses simple pattern-matching to find instances of the application running on the monitored computer.
PSL discovery uses scripts written in PATROL Script Language to find the application instances.
