Integration of Custom Defined Monitor in Serviceguard Using Generic Resources
The feature, generic resources is a resource monitoring mechanism in Serviceguard that allows
you to monitor critical resources for a package through custom monitors, by configuring these
monitors as user-defined services. It provides integration of custom, user-defined monitors in
Serviceguard by configuring the generic resource parameters as part of package configuration.

Linux manual.

resource.
