LogError

LogError is a term used in software engineering to denote an event or operation that records an error condition in a system's logging framework. It typically represents the highest severity commonly used in logs, capturing messages, error codes, exceptions, and stack traces when something goes wrong. LogError entries are designed to aid debugging, monitoring, and incident response.

In practice, LogError may take the form of a function or method call (for example, logError or logger.error) that outputs a message tagged with the error level. Some languages provide overloads or variants that accept an exception object, a structured payload, or contextual metadata such as user IDs or request IDs. It is often distinct from non-error levels like Info or Debug.

Design considerations for using LogError include ensuring consistent severity naming, avoiding overly verbose messages, and protecting sensitive data. Many systems support asynchronous or batched logging, log rotation, and centralized aggregation. Structured logging for LogError entries—employing key-value fields—facilitates searching and correlation with traces and alerts across distributed services.

LogError is a common concept across languages and platforms, with implementations varying by framework. It serves as a standard cue for operators and automated systems to triage failures, enabling faster diagnosis and remediation.
