is installed. A system has one agent per resource type that monitors all resources<br />
of that type; for example, a single IP agent manages all IP resources.<br />
When the agent is started, it obtains the necessary configuration information<br />
from VCS. It then periodically monitors the resources, and updates VCS with the<br />
resource status.<br />
