##Log rotate

# /etc/logrotate.d/azure_logs

/opt/AZURE/*.txt {
    weekly
    missingok
    rotate 4
    compress
    delaycompress
    notifempty
    create 0644 root root
}

~/.azcopy/*.log {
    weekly
    missingok
    rotate 4
    compress
    delaycompress
    notifempty
    create 0644 root root
}

Explanation:

• weekly: Rotate the logs on a weekly basis.
• missingok: If the log file is missing, go on to the next one without issuing an error message.
• rotate 4: Keep only the last 4 weeks of logs.
• compress: Compress the rotated logs using gzip.
• delaycompress: Delay compression until the next rotation cycle. This means the current log file will not be compressed immediately after rotation, but the previous log files will be.
• notifempty: Do not rotate the log if it is empty.
• create 0644 root root: Create new log files with owner root and group root, and permissions 0644.

Steps to Apply the Configuration:

1. Save the above configuration in /etc/logrotate.d/azure_logs.
2. Ensure that the logrotate service is enabled and running on your system.
3. Test the logrotate configuration with the following command to ensure there are no syntax errors:

sudo logrotate -d /etc/logrotate.d/azure_logs

The -d option runs logrotate in debug mode, which will show you what actions would be taken without actually performing them.

4. If everything looks good, you can force a rotation to test it:

sudo logrotate -f /etc/logrotate.d/azure_logs

This will rotate the logs immediately according to the specified configuration.

By following these steps, your logs in /opt/AZURE and ~/.azcopy should be rotated weekly, compressed, and kept for only the last 4 weeks.
