About vFoglight Cartridges
A cartridge is a unit that is distributed separately from the vFoglight Management
Server, but can be added to the Management Server. A cartridge contains components
that extend the functionality of vFoglight, such as agent installers, communication
capabilities, modifications to the way that data is transformed or handled, model
definitions, rules, reports, and views.
An installation of the vFoglight Management Server includes a collection of core
cartridges, including the Monitoring Policy, Service Model, and other core cartridges.
Core cartridges are installed with the server, and are enabled on its startup. Along with
the core cartridges, your configuration can include other cartridges that are installed
additionally on the server and are designed to monitor specific types of environments,
such as the OS cartridge. Both core and installed cartridges can contain a set of rules,
registry variables, tables, retention policies, and other vFoglight entities.
The following concepts and terms relate to cartridge management in vFoglight:
• Cartridge. A unit that is distributed separately from the vFoglight Management
Server. Cartridges contain components that extend the functionality of vFoglight,
such as agents, rules, and views.
• Cartridge installation. The act of installing a cartridge on the machine hosting the
vFoglight Management Server. Cartridge installation makes the Management
Server aware of the cartridge.

Server and available for use by vFoglight.
