Logging is the first thing we learn when learn how to write code.
It enable us to track the behavior of our applications and identify issues. It involves capturing and storing information about events that occur during the execution of our programs.
For example, in a Node.js application, logging can be implemented using a popular library like Winston. You can use Winston to log various types of messages, such as errors, warnings, or information about specific events in the application. These logs can then be stored in files or sent to a centralized log management system for further analysis.
Logging alone starts to show its limitation in a distributed systems, where distributed tracing becomes more crucial for understanding the interactions between different services. Solutions like OpenTelemetry can be used to instrument applications and capture distributed traces and logs, providing a comprehensive view of the entire system's behavior.
