programLevel

Programlevel is a term used in software engineering to denote the current level, stage, or scope of a program's execution or configuration. There is no single universal definition, and the exact meaning of programlevel depends on the context and the project that uses it. In configuration files, programlevel can be a key that selects behavior appropriate to different software stages, such as development, testing, or production.

In logging and observability, a programlevel field can classify messages by the program’s state or phase, enabling filtering and correlation across components. For example, messages might be labeled with levels that indicate initialization, startup, steady operation, or shutdown, helping operators diagnose issues based on the program’s lifecycle.

In state machines or workflow engines, programlevel can indicate hierarchical depth or the nesting level of processes, such as level 1 for the main flow and level 2 for subroutines. In build and deployment pipelines, a similar concept may exist to denote the current phase or artifact level, though many teams prefer terms like stage, phase, or environment.

Common values for programlevel are typically simple, such as integers (0–5) or strings like "development", "staging", "production", or lifecycle labels such as "init", "run", and "terminate". Because the term lacks a formal standard, its exact semantics are defined by the project, library, or framework that introduces it. See also: level, phase, environment, logging level.
