Label: logging

Logging is the process of recording information about how a program or system operates. Applications write log messages to help developers monitor behavior, detect errors, and diagnose problems. Logs may contain status messages, warnings, debug information, performance metrics, or security events. Modern software often supports multiple log levels such as INFO, WARNING, ERROR, and DEBUG. Log data can be written to files, consoles, system services, or remote servers. Structured log output formats like JSON are commonly used for automated analysis and monitoring. Efficient logging is important because excessive overhead can reduce application performance. Logging plays a critical role in debugging, observability, security analysis, and production support.

Understanding logging is essential for software development, troubleshooting, and system monitoring.

FileBackend in Production: C++ Log Rotation with logme

By Eduard Mishkurov

Logging, С++

0

Writing log messages to a file is easy. Keeping file logging predictable after months of production use is much harder. An active log file must not grow forever. Old logs need to be preserved for a useful period, but they also need to be deleted eventually. Finished files may need compression. At the same time,

Thread-Local Logging Context in C++: Using Thread-Local Context in logme

By Eduard Mishkurov

Logging, С++

A useful log should do more than tell you what happened. It should also make it clear which request, connection, client, or background job a message belongs to. When an application is still small, this usually seems easy enough. You can just include the extra data directly in the log call: LogmeI( "Request %s: loading

Log Source Profiling: Which Log Statement Is Responsible?

Logging, С++

How log source profiling traces CPU and file I/O back to individual C and C++ call sites without disabling production diagnostics Log source profiling starts where a normal CPU profiler stops. A system profiler can tell you that a logging thread is consuming CPU and show write(), a file-backend worker, queue synchronization, memory copies, and

Migrating from glog to logme: LOG, CHECK, PLOG, and VLOG in a New Logging Model

By Eduard Mishkurov

Logging, С++

0

Migrating from glog to logme does not have to start with a full rewrite of every logging call. In large C++ projects, that is usually the wrong first step. Logging statements are spread across the codebase, and they often sit next to checks, conditions, diagnostic messages, CHECK, PLOG, VLOG, and debug-only calls. Replacing everything at
