A daemon is a reserved background Java thread that executes as a BATCH requestor type. Daemons behave similarly to an agent, but daemons are not defined by a Rule-Agent-Queue rule type, are not full requestors, and operate continuously and automatically. The Pega Platform includes the following daemons: License Compliance, Master-for-Agent, Master-for-Requestors, Node, Passivation, and Usage.
