Journald is a logging system used in modern Linux-based operating systems to record system events. It collects information about the operation of various services, applications, and system processes to help administrators monitor system health and diagnose errors.

Unlike standard text logs, journald stores data in a binary format. This allows logs to be stored more compactly and managed more efficiently, but at the same time, you cannot simply open these logs in a text editor. Special tools are required to view and analyze them.

In this article, we will look at how to view the records maintained by journald and how to clear them to save disk space.

Log management is a crucial part of any server administrator's job. Logs that are not rotated can quickly occupy all available disk space, slow down the server, and cause unpredictable errors. In this article, we’ll explain how to configure and use logrotate for automatic log cleanup and rotation on a server. 

Logs are files that store information about server events: application and operating system activity, various errors, user requests to websites, and more. Over time, logs can take up a significant amount of disk space, especially under heavy load or if there are software errors.

One critical aspect of log files is that, in most cases, deleting them can cause issues for the program generating them — whether it’s a web server or even the operating system itself.

Additionally, logs often contain valuable diagnostic information that can help identify software issues on your server and prevent larger problems. Therefore, it’s important to handle them properly and carefully.
