Logrotateohjelma

Logrotateohjelma is a utility designed for the automatic management of log files on Unix-like operating systems. Its primary function is to rotate, compress, remove, and mail log files. This process is crucial for preventing log files from consuming excessive disk space and for making them more manageable for analysis.

The program works by processing configuration files, typically located in `/etc/logrotate.conf` and files within the `/etc/logrotate.d/` directory. Each configuration file specifies rules for individual log files or groups of files. These rules can include directives such as the frequency of rotation (daily, weekly, monthly, or simply when a file reaches a certain size), the number of old log files to keep, and whether to compress the rotated logs.

Common directives allow for the execution of scripts before or after the rotation process, enabling custom actions like restarting logging daemons to ensure they start writing to a new log file. Logrotateohjelma can also be configured to send rotated logs via email to a specified address, which can be useful for remote log analysis or archival. The utility is typically run as a daily cron job, ensuring that log management occurs automatically without manual intervention. Its flexibility makes it a standard tool for system administrators tasked with maintaining system health and performance.
