Finding the logs you need to troubleshoot an issue can often feel like looking for a needle in a haystack, especially if you need to manually sift through large volumes of log files, individual log files that are too large, or both. On top of that, tasks like searching through log files with commands like grep become more computationally expensive and time consuming as their size increases. A primary concern for system administrators is that log files can quickly take up a resource’s available disk space, requiring additional maintenance and on-demand capacity that can significantly drive up costs. Logging to files, while recommended, presents its own set of challenges when it comes to implementation at scale. Rotate your logs with the logrotate utility

Logging to files ensures that you always have access to the information you need for identifying security threats and troubleshooting application issues, even (or especially) in the case of a production issue. For example, an application that does not leverage file-based logging may attempt to execute resource-intensive retry logic multiple times in order to resume log streams during an outage.

In this guide, we’ll walk you through how to customize the logrotate utility to fit your logging needs. Logrotate is a Linux utility designed to simplify log management and maintenance within these types of environments through a process known as log rotation. Large-scale production environments emit enormous quantities of logs, which can make them more challenging to manage and introduces the risk of losing important data if underlying resources run out of space. Logs are records of system events and activities that provide valuable information used to support a wide range of administrative tasks-from analyzing application performance and debugging system errors to investigating security and compliance issues.
