DESCRIPTION

This utility allow you to maintain the audit log[1], allowing you to monitor the audit log
file growth and control its rotation. 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.

This utility allows you 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).

The available actions include the following:

1. 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.

2. policy

The policy command is used to change the audit logging policy. The accepted values are
the following, which are set using the --value option.

Note
The --server option is also required to execute this command.

· ALL: log all events

· NONE: log nothing

· LOGINS: only log login events

· QUERIES: only log query events

· DEFAULT: sets the default log policy

3. 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.

4. 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 variable).
OPTIONS

mysqlauditadmin accepts the following command-line options:

· --audit-log-name=<AUDIT_LOG_FILE>

Full path and file name 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.

· --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 in the format:
<user>[:<passwd>]@<host>[:<port>][:<socket>] or <login-path>[:<port>][:<socket>].

· --show-options

Display the audit log system variables.

· --value=<VALUE>

Value used to set variables based on the specified commands, such as policy and
rotate_on_size.

· --server1=<source>

Connection information for the first server in the format:
<user>[:<passwd>]@<host>[:<port>][:<socket>] or <login-path>[:<port>][:<socket>].

· --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

This utility is available as of μ 1.2.0.

This utility can only be applied to servers with the audit log plugin enabled[2]. 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[3].
LIMITATIONS

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

To display the audit log system variables, run the following command:

$ mysqlauditadmin --show-options --server=root@localhost:3310
#
# Audit Log Variables and Options
#
+---------------------------+---------------+
| Variable_name | Value |
+---------------------------+---------------+
| audit_log_buffer_size | 1048576 |
| audit_log_file | audit.log |
| audit_log_flush | OFF |
| audit_log_policy | ALL |
| audit_log_rotate_on_size | 0 |
| audit_log_strategy | ASYNCHRONOUS |
+---------------------------+---------------+

To perform a (manual) rotation of the audit log file, use the following command:

shell> mysqlauditadmin --server=root@localhost:3310 rotate
#
# Executing ROTATE command.
#

To display the audit log file statistics, run the following command:

shell> mysqlauditadmin --file-stats --audit-log-name=../SERVER/data/audit.log
+------------------------------+--------+---------------------------+---------------------------+
| File | Size | Created | Last Modified |
+------------------------------+--------+---------------------------+---------------------------+
| audit.log | 3258 | Wed Sep 26 11:07:43 2012 | Wed Sep 26 11:07:43 2012 |
| audit.log.13486539046497235 | 47317 | Wed Sep 26 11:05:04 2012 | Wed Sep 26 11:05:04 2012 |
+------------------------------+--------+---------------------------+---------------------------+

To change the audit log policy to log only query events, and show the system variables
before and after the execution of the policy command, use the following command:

shell> mysqlauditadmin --show-options --server=root@localhost:3310 policy \
--value=QUERIES
#
# Showing options before command.
#
# Audit Log Variables and Options
#
+---------------------------+---------------+

| audit_log_buffer_size | 1048576 |
| audit_log_file | audit.log |
| audit_log_flush | OFF |
| audit_log_policy | ALL |
| audit_log_rotate_on_size | 0 |
| audit_log_strategy | ASYNCHRONOUS |
+---------------------------+---------------+
#
# Executing POLICY command.
#
#
# Showing options after command.
#
# Audit Log Variables and Options
#
+---------------------------+---------------+

| audit_log_rotate_on_size | 0 |
| audit_log_strategy | ASYNCHRONOUS |
+---------------------------+---------------+

To change the audit log automatic file rotation size to 32535, and show the system
variables before and after the execution of the rotate_on_size command, use the following
command. (Notice that the value set is actually 28672 because the specified rotate_on_size
value is truncated to a multiple of 4096):

shell> mysqlauditadmin --show-options --server=root@localhost:3310 rotate_on_size \
--value=32535
#
# Showing options before command.
#
# Audit Log Variables and Options

| audit_log_file | audit.log |
| audit_log_flush | OFF |
| audit_log_policy | ALL |
| audit_log_rotate_on_size | 0 |
| audit_log_strategy | ASYNCHRONOUS |
+---------------------------+---------------+
#
# Executing ROTATE_ON_SIZE command.

To perform a copy of a audit log file to another location, use the following command:

shell> mysqlauditadmin --audit-log-name=../SERVER/data/audit.log.13486539046497235 \
copy --copy-to=/BACKUP/Audit_Logs

To copy a audit log file from a remote server/location to the current location (user
password will be prompted), use the following command:

shell> mysqlauditadmin --audit-log-name=audit.log.13486539046497235 \
copy --remote-login=user:host --copy-to=.
