An entry point is either a C++ function or a script (shell or Perl, for example) used by the agent to carry out a specific task on a resource. The agent framework supports a specific set of entry points, each of which is expected to do a different task and return. For example, the online entry point brings a resource online.
An agent developer implements the entry points for a resource type that the agent uses to carry out the required tasks on the resources of that type. For example, in the online entry point for the Mount type, the agent developer includes the logic to mount a file system based on the parameters provided to the entry point. These parameters are attributes for a particular resource, for example, mount point, device name, and mount options. In the monitor entry point, the agent developer checks the state of the mount resource and returns a code to indicate whether the mount resource is online or offline.
