DESCRIPTION
This utility allows you to maintain the audit log including the ability to view and modify a subset of
audit log control variables, display the audit log file status, perform on-demand rotation of the log
file, and copy files to other locations. These features enable you to easily monitor the audit log file
growth and control its rotation (automatically based on the defined file size threshold, or manually by a
on-demand command).
Rotation refers to the action of replacing the current audit log file by a new one for continuous use,
renaming (with a timestamp extension) and copying the previously used audit log file to a defined
location for archival purposes.
The available actions include the following:
• copy
This command copies the audit log specified by --audit-log-name to the destination path specified by
--copy-to. The --remote-login option can be used to copy log files from a remote location. Note: the
destination path must be locally accessible by the current user.
• policy
The policy command is used to change the audit logging policy. The accepted values include the
following, which are set using the --value option.
Note
The --server option is also required to execute this command.
Starting from MySQL server 5.6.20 and 5.7.5, the value is read only for the audit_log_policy
variable. MySQL server 5.7.9 introduced two new variables: audit_log_connection_policy and
audit_log_statement_policy whose values are determined based on the presence and value of the
audit_log_policy startup variable. See the MySQL reference manual for more information about how
the policy variables are set. These changes are supported starting from MySQL Utilities 1.5.2.
• ALL: log all events
• NONE: log nothing
• LOGINS: only log login events
• QUERIES: only log query events
• DEFAULT: sets the default log policy
• rotate_on_size
This command sets the file size threshold for automatic rotation of the audit log (the
audit_log_rotate_on_size variable). The value is set using the --value option, and must be in the
range (0, 4294967295). This command also requires the --server option to be specified. Note: if the
variable is set with a value that is not a multiple of 4096, then it is truncated to the nearest
multiple.
• rotate
This command is used to perform an on-demand audit log rotation, and only requires the --server
option to be passed. Note: this command has no effect if the audit log file size is smaller than
4096, which is the minimum value allowed that is greater than 0 for the audit_log_rotate_on_size
variable).
OPTIONS.PP mysqlauditadmin accepts the following command-line options:
• --audit-log-name=<AUDIT_LOG_FILE>
Full path and filename for the audit log file. Used by the --file-stats option, and the copy command.
• --copy-to=<COPY_DESTINATION>
The location to copy the specified audit log file. The path must be locally accessible for the
current user.
• --file-stats
Display the audit log file statistics.
• --help
Display a help message and exit.
• --license
Display license information and exit.
• --remote-login=<REMOTE_LOGIN>
User name and host to be used for the remote login, for copying log files. It is defined using the
following format: <user>:<host or IP>. Usage will prompt for the password.
• --server=<SERVER>
Connection information for the server.
To connect to a server, it is necessary to specify connection parameters such as the user name, host
name, password, and either a port or socket. MySQL Utilities provides a number of ways to supply this
information. All of the methods require specifying your choice via a command-line option such as
--server, --master, --slave, etc. The methods include the following in order of most secure to least
secure.
• Use login-paths from your .mylogin.cnf file (encrypted, not visible). Example :
<login-path>[:<port>][:<socket>]
• Use a configuration file (unencrypted, not visible) Note: available in release-1.5.0. Example :
<configuration-file-path>[:<section>]
• Specify the data on the command-line (unencrypted, visible). Example :
<user>[:<passwd>]@<host>[:<port>][:<socket>]
• --show-options
Display the audit log system variables.
• --ssl-ca
The path to a file that contains a list of trusted SSL CAs.
• --ssl-cert
The name of the SSL certificate file to use for establishing a secure connection.
• --ssl-cert
The name of the SSL key file to use for establishing a secure connection.
• --ssl
Specifies if the server connection requires use of SSL. If an encrypted connection cannot be
established, the connection attempt fails. Default setting is 0 (SSL not required).
• --value=<VALUE>
Value used to set variables based on the specified commands, such as policy and rotate_on_size.
• --verbose, -v
Specify how much information to display. Use this option multiple times to increase the amount of
information. For example, -v = verbose, -vv = more verbose, -vvv = debug.
• --version
Display version information and exit.
NOTES.PP This utility can only be applied to servers with the audit log plugin enabled. And the audit log
plugin is available as of MySQL Server versions 5.5.28 and 5.6.10.
This utility requires Python version 2.6 or higher, but does not support Python 3.
The path to the MySQL client tools should be included in the PATH environment variable in order to use
the authentication mechanism with login-paths. This will allow the utility to use the my_print_defaults
tools, which is required to read the login-path values from the login configuration file (.mylogin.cnf).
This feature exists as of MySQL Server 5.6.6, see mysql_config_editor — MySQL Configuration Utility[1].
Changes to MySQL Enterprise Audit are not documented here, so your output might be different than the
examples shown. For example, a new (or removed) MySQL Enterprise Audit option might affect the output.
LIMITATIONS.PP The --remote-login option is not supported on Microsoft Windows platforms. For Microsoft
Windows, use UNC paths and perform a local copy operation, omitting the
--remote-login option. EXAMPLES.PP To display the audit log system variables, run the following
command:
shell> mysqlauditadmin --show-options --server=root@localhost:3310
#
# Showing options after command.
