Logrotate runs daily as a cron job, going through various log files, rotating them, and purging older log files as defined in the configuration file. There are two main configuration sources that you need to pay close attention to:. It contains default settings and facilitates log rotation for non-system package logs.
We need to set the log files to rotate on a weekly basis. The log files will be rotated on a weekly basis, with suppression of any error messages if any of the log files are missing. Now we are going to create a logs directory that will contain the log files of the application and then create a log file called app. Now, we will run the logrotate command to create a logrotate state file in the home directory in order to verify if the log entries have been created or not.
From the output, the log file was not rotated for the simple reason that rotation occurs weekly and the log file is barely an hour old. Examine the logrotate file to verify if there was any information recorded about the log rotation run.
From the output, we can see that the logrotate utility acknowledged when last it considered the log file for rotation, and the timestamp is printed. If you head back to the logs directory, you will observe an additional log file that has been rotated and compressed as shown. Sometimes, log files can grow bigger and gobble up space even before the specified time interval for rotation, whether daily, weekly or monthly.
One way to resolve the issue is to specify the maximum size of the file which when exceeded, rotation of the log file will be triggered.
