   sudo vim /etc/logrotate.d/rsyslog

2. Modify the configuration to set up hourly rotation.

   1. Change the rotate directive to 6. rotate 6

   2. Change the weekly directive to hourly. hourly

   3. Add the maxsize directive if it is not already present. maxsize 0

3. Test the configuration to ensure there are no syntax errors.

   sudo logrotate -d /etc/logrotate.conf

4. Open the logrotate timer configuration file in a text editor.

   sudo nano /lib/systemd/system/logrotate.timer

5. Modify the timer to trigger log rotation hourly. Change OnCalendar=daily to OnCalendar=hourly

6. Restart the logrotate.timer to apply the changes.

   sudo systemctl daemon-reload
   sudo systemctl restart logrotate.timer

7. If needed, clear other log files using the following commands to free up more storage.

   sudo rm -f /var/log/*.gz /var/log/*.1 /var/log/*.old
