Managing log files
About logging with Cloud 66
When Cloud 66 deploys your servers, we also configure the logging for various services on your server. There are several logs available for different parts of your server. Depending on the specifics of your application, log names and directories may vary. The information below applies to most applications.
Ruby stacks
Web logs
Web logs are stored in $STACK_PATH/log:
- Web logger:
$STACK_PATH/log/<environment>.log
- Nginx error log:
$STACK_PATH/log/nginx_error.log
If you are using a custom web server, such as Unicorn, you can find your web server bluepill logs in /tmp/web_server_bluepill.log.
Background processes
Logs for background processes can also be found in $STACK_PATH/log, and depend on the name of the process:
- Process log:
$STACK_PATH/log/user_<name>.log
- Process bluepill log:
$STACK_PATH/log/user_<name>.pill
Other
- Auth requests, Fail2Ban etc:
/var/log
- Nginx access and errors:
/opt/nginx/logs
Log rotation
Your logs in $STACK_PATH/log and /var/log are automatically rotated on a daily basis and by default kept for 14 days into a sub-directory called archive/ in each respective directory. These logs are compressed, and can be uncompressed with the following command: gzip -d <log_file>.log.gz.
Note
You can set the frequency and the number of rotations to be kept using toolbelt.
