diagstatus

Diagstatus is a term used in information technology and engineering to denote the outcome or current state of a diagnostic test, check, or procedure. It typically appears as a field in diagnostic data structures, logs, or API responses. The purpose is to convey whether a component, subsystem, or process is operating normally or requires attention, enabling automated systems to take appropriate action.

The actual values of diagstatus vary by system, but common patterns include categorical statuses such as OK, WARN, ERROR, FAIL, and PENDING, as well as numeric codes like 0 for success and non-zero values for various failure categories. Some implementations use strings such as "ok", "failed", or "unknown". In many cases a numeric code is mapped to a human-readable message in a log or user interface.

Diagstatus is used across domains, including embedded devices performing self-tests during startup, network devices reporting the health of interfaces or services, and software health endpoints that expose diagstatus in REST or SNMP responses. It supports automation by allowing monitoring systems to trigger alerts when the status indicates problems or to route remediation workflows.

Best practices for diagstatus include defining a clear, finite set of statuses, documenting the exact meaning of each value, ensuring consistent usage across components, and including timestamps and contextual details with status updates. Consider versioning the status schema and providing localization for messages in user-facing interfaces.
