dagent

Dagent is a term used in computing to refer to a software component that runs in the background to perform automated tasks on behalf of a host application or system. The name is not tied to a single, universal product; rather, it denotes a class of processes that function as daemons, agents, or services in various software environments. Because of its generic nature, dagent can describe different implementations across projects, architectures, and platforms.

In typical use, a dagent acts as an autonomous executor and communicator. Common roles include collecting data (such as metrics or logs), performing routine maintenance or remediation tasks, coordinating job execution or workflow steps, and bridging interactions between systems via APIs or messaging protocols. A dagent often runs persistently on a machine or within a container, listening for instructions, polling resources, or responding to events signaled by other components.

Architecturally, dagents usually comprise a lightweight runtime, a configuration mechanism, and a communication layer. They may expose REST or gRPC interfaces, subscribe to message queues, or communicate through secure channels with a central manager or control plane. Security considerations typically emphasize least-privilege operation, encrypted communication, and robust authentication and authorization for remote management.

In some workflows, the concept of a dagent is related to directed-acyclic-graph (DAG) processing, where an agent executes tasks while honoring dependencies defined in a graph. Terminology and exact features can vary by project, so references to dagent are best understood in the specific context of the software or system in question.
