procPID

Procpid is a label used in computing to refer to a process identifier, often appearing in the context of logging, debugging, and monitoring. It is not defined by a universal standard, but rather serves as a convenient shorthand in various software environments for the numeric identifier assigned by the operating system to a running process.

In practice, a procpid typically corresponds to the system’s process ID (PID). It is used to distinguish events, metrics, or traces that originate from different processes, especially in multi-process architectures such as web servers with multiple workers, background job runners, or containerized applications. Logs or monitoring outputs may include a procpid field so developers and operators can correlate actions across different subsystems for the same process.

Because procpid is not standardized, its presence and exact labeling can vary by platform or tool. Some systems expose a field named procpid, while others may use pid, process_id, or a similar term. In some environments, procpid may be shown only in verbose logging or certain debugging formats and may not appear in all views of the same application.

Overall, procpid is best understood as a practical alias for the underlying process ID, used to help track and analyze the behavior of individual processes within a broader system. See also: PID, process ID, logging, monitoring, ps command, /proc.
