What are some examples of custom log rotation configurations?

Custom log rotation configurations can vary based on your needs. For instance, you can set up daily rotation for web server logs, keeping the last 7 days of logs, or configure monthly rotation for application logs, retaining logs for 6 months.

Can you show me a specific example for Apache logs?

Sure! For Apache logs, you can use the following configuration in your logrotate file:

/var/log/apache2/*.log {
    daily
    missingok
    rotate 14
    compress
    delaycompress
    notifempty
    create 640 www-data adm
}

This rotates the logs daily, keeps 14 days of logs, and compresses old logs.

What about rotating logs for a Node.js application?

For a Node.js application, you might configure log rotation like this:

/var/log/myapp/*.log {
    weekly
    rotate 4
    compress
    delaycompress
    missingok
    notifempty
}

This setup rotates logs weekly and keeps 4 weeks of logs.

Are there any best practices for log rotation?

Yes, some best practices include setting appropriate retention periods based on your needs, ensuring logs are compressed to save space, and monitoring log sizes to adjust rotation frequency as necessary.
