We are generating sample Apache access logs each day at 00:00 UTC, so that provides 24 hours of access logs for you to play with. You can download it here. (There is a new file each day.) Once you have the file, you can use our fancy "File Upload" endpoint to ingest it:
curl -T apache-daily-access.log https://listener.logz.io:8022/file_upload/<TOKEN>/apache-access
Just wait one minute, and the logs will appear in your account!
After you do that, make sure to visit the ELK Apps tab to download appropriate Apache dashboards, visualizations, and alerts.
