nodstatus

Nodstatus is a term used in distributed computing to refer to a component or protocol that reports the status of individual nodes within a network, cluster, or grid. It may function as an agent running on each node and/or as a centralized service that aggregates status information. The primary purpose is to facilitate monitoring, orchestration, and failure detection by providing up-to-date visibility into node health and capacity.

Data model: common fields include node_id, host, role, status (up, down, maintenance), last_seen, uptime, cpu_load, memory_usage, disk_usage, network_io, capacity, tasks_active, and temperature if available.

Operations: nodstatus typically supports periodic heartbeats, on-demand status requests, and event-driven updates. Interfaces may include RESTful HTTP, gRPC, or message bus protocols. Security features often include TLS, authentication tokens, and access control.

Architectures: nodstatus can be implemented as a centralized collector with per-node agents, a fully federated model where nodes publish to regional brokers, or as a hybrid with push and pull components. It is commonly used in cloud infrastructure, high-performance computing clusters, and IoT fleets to support dashboards, alerting, and automated scaling.

Usage: in practice, nodstatus informs dashboards, alerts, and orchestration decisions. Operators may configure health checks, thresholds, and alert routing, while automation pipelines can trigger remediation or scale-out actions based on status data.

History: the concept aligns with general best practices in distributed systems for node visibility and reliability, with implementation variants across platforms and vendors.
