Logging is an art form, and log messages are one of the primary tools developers use to troubleshoot issues in production. However, the importance of logging standards is often overlooked by developers. Logs are like insurance; they might not seem necessary during normal operations, but they become invaluable when something goes wrong. A well-crafted log entry serves as our evidence to the outside world.
Logs Introduction
What Are Logs
Logs, as defined by Wiki, are one or more log files automatically created and maintained by a server, containing a list of activities it performs.
A well-maintained log file provides developers with an accurate record of the system, aiding in pinpointing the details and root causes of system errors. In Java applications, log files are commonly used to record critical logical parameters and exceptions during the application’s runtime, supported by log collection systems (like ELK, DTM) to build a system monitoring framework.
