Audit Log File Format

Each node in a cluster will create its own files using the following naming convention:

auditlog_<hostname>-<port>_<year>-<month>-<day>_<hour>-<minute>-<second>.log

For example, consider the following log file name:

auditlog_myVmbox-3306_2016-08-30_06-38-46.log

If a log file’s rotation size is very small, an auto-incrementing integer may be appended to the end of the log file. For example:

auditlog_myVmbox-3306_2016-08-30_06-38-46_1.log
auditlog_myVmbox-3306_2016-08-30_06-38-46_2.log
auditlog_myVmbox-3306_2016-08-30_06-38-46_3.log

Data within the log file is written in comma-separated values (CSV) format. Log files are updated immediately as queries are executed; they are not cached locally and then eventually written to the destination directory.
