mysqlauditgrep: Search an audit log

NAME

mysqlauditgrep - Search an audit log

SYNOPSIS

mysqlauditgrep [OPTIONS]... AUDIT_LOG_FILE mysqlauditgrep --file-stats[--format=FORMAT] AUDIT_LOG_FILE mysqlauditgrep --format=FORMATAUDIT_LOG_FILE mysqlauditgrep [--users=USERS] [--start-date=START_DATE] [--end-date=END_DATE] [--pattern=PATTERN[--regexp]] [--query-type=QUERY_TYPE] [--event-type=EVENT_TYPE] [--status=STATUS] [--format=FORMAT] AUDIT_LOG_FILE

DESCRIPTION

This utility allows you to search the current or archived audit logs, allowing you to display data from the audit log file according to the defined search criterion. It also allows you to output the results in different formats, namely GRID (default), TAB, CSV, VERTICAL, and RAW (the original XML format).

This utility allows you to search and filter the returned audit log records by: users (--users), date and time ranges (--start-date and --end-date), SQL query types (--query-type), logged event and record types (--event-type), status (--status), and matching patterns (--pattern). Any of these search options can be combined and used together, with the retrieved records resulting from all passed in options being true.

The --pattern supports two types of pattern matching: standard SQL, used with the SQL LIKE operator (SQL patterns), and standard REGEXP (POSIX regular expression patterns).

This utility always requires an audit log file to be passed in, so the AUDIT_LOG_FILE argument is searched as a full path and file name for the audit log file. If not specified, a notification concerning this requirement will be printed. And if --format is passed in without search parameters, then all the records of the audit log are displayed in the specified format.

The --file-stats option is not considered a search criteria, and is used to display the file statistics of a specified audit log. Other search options will be ignored when the --file-stats option is used, except the --format option will continue to format the results accordingly.

To specify the format of the generated results, use one of the following values with the --format option:

1. GRID (default)

Display output in grid or table format like that of the mysql monitor.

2. CSV

Display output in comma-separated values format.

3. VERTICAL

Display output in single-column format like that of the \G command for the mysql monitor.

4. RAW

Display output results in the original raw format of the audit log records, which is written in XML.


Standard SQL Pattern Matching

The simple patterns defined by the SQL standard enables users to use two characters with special meanings: "%" (percent) matches zero or more characters, and "_" (underscore) matches exactly one arbitrary character. In standard SQL, these types of patterns are used with the LIKE comparison operator, and they are case-insensitive by default. This utility assumes that they are case-insensitive.

For example:

• "audit%"

Match any string that starts with "audit".

• "%log%"

Match any string containing the word "log".

• "%_"

Match any string consisting of one or more characters.

For documentation about the standard SQL pattern matching syntax, see m[blue]Pattern Matchingm[][1].
REGEXP Pattern Matching (POSIX)

Standard REGEXP patterns are more powerful than the simple patterns defined in the SQL standard. A regular expression is a string of ordinary and special characters specified to match other strings. Unlike SQL Patterns, REGEXP patterns are case-sensitive. The REGEXP syntax defines the following characters with special meaning:

• .

Match any character.

• ^

Match the beginning of a string.

• $

Match the end of a string.

• \

Match zero or more repetitions of the preceding regular expression.

• +

Match one or more repetitions of the preceding regular expression.

• ?

Match zero or one repetition of the preceding regular expression.

• |

Match either the regular expressions from the left or right of |.

• []

Indicates a set of characters to match. Note that, special characters lose their special meaning inside sets. In particular, ^ acquires a different meaning if it is the first character of the set, matching the complementary set (i.e., all the characters that are not in the set will be matched).

• {m}

Match m repetitions of the preceding regular expression.

• {m,n}

Match from m to n repetitions of the preceding regular expression.

• ()

Define a matching group, and matches the regular expression inside the parentheses.

For example:

• "a\*"

Match a sequence of zero or more a.

• "a+"

Match a sequence of one or more a.

• "a?"

Match zero or one a.

• "ab|cd"

Match ab or cd.

• "[axy]"

Match a, x or y.

• "[a-f]"

Match any character in the range a to f (that is, a, b, c, d, e, or f).

• "[^axy]"

Match any character excepta, x or y.

• "a{5}"

Match exactly five copies of a.

• "a{2,5}"

Match from two to five copies of a.

• "(abc)+"

Match one or more repetitions of abc.

This is a brief overview of regular expressions that can be used to define this type of patterns. The full syntax is described in the m[blue]Python "re" module docsm[][2], supporting the definition of much more complex pattern matching expression.
OPTIONS

mysqlauditgrep accepts the following command-line options:

• --end-date=<END_DATE>

End date/time to retrieve log entries until the specified date/time range. If not specified or the value is 0, all entries to the end of the log are displayed. Accepted formats: "yyyy-mm-ddThh:mm:ss" or "yyyy-mm-dd".

• --event-type=<EVENT_TYPE>

Comma-separated list of event types to search in all audit log records matching the specified types. Supported values are: Audit, Binlog Dump, Change user, Close stmt, Connect Out, Connect, Create DB, Daemon, Debug, Delayed insert, Drop DB, Execute, Fetch, Field List, Init DB, Kill, Long Data, NoAudit, Ping, Prepare, Processlist, Query, Quit, Refresh, Register Slave, Reset stmt, Set option, Shutdown, Sleep, Statistics, Table Dump, Time.

• --file-stats

Display the audit log file statistics.

• --format=FORMAT, -f FORMAT

Output format to display the resulting data. Supported format values: GRID (default), TAB, CSV, VERTICAL and RAW.

• --help

Display a help message and exit.

• --pattern=<PATTERN>, -e <PATTERN>

Search pattern to retrieve all entries with at least one attribute value matching the specified pattern. By default the standard SQL LIKE patterns are used for matching. If the --regexp option is set, then REGEXP patterns must be specified for matching.

• --query-type=<QUERY_TYPE>

Comma-separated list of SQL statements/commands to search for and match. Supported values: CREATE, ALTER, DROP, TRUNCATE, RENAME, GRANT, REVOKE, SELECT, INSERT, UPDATE, DELETE, COMMIT, SHOW, SET, CALL, PREPARE, EXECUTE, DEALLOCATE.

• --regexp, --basic-regexp, -G

Indicates that pattern matching will be performed using a regular expression REGEXP (from the Python re module). By default, the simple standard SQL LIKE patterns are used for matching. This affects how the value specified by the --pattern option is interpreted.

• --start-date=<START_DATE>

Starting date/time to retrieve log entries from the specified date/time range. If not specified or the value is 0, all entries from the start of the log are displayed. Accepted formats: yyyy-mm-ddThh:mm:ss or yyyy-mm-dd.

• --status=<STATUS>

Comma-separated list of status values or intervals to search for all audit log records with a matching status. Status values are non-negative integers (corresponding to MySQL error codes). Status intervals are closed (i.e., include both endpoints) and defined simply using a dash between its endpoints. For Example: 1051,1068-1075,1109,1146.

The --status option is available as of MySQL Utilities 1.2.4 / 1.3.3.

• --users=<USERS>, -u <USERS>

Comma-separated list of user names, to search for their associated log entries. For example: "dan,jon,john,paul,philip,stefan".

• --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 m[blue]audit log plugin enabledm[][3]. And the audit log plugin is available as of MySQL Server versions 5.5.28 and 5.6.10.

This utility requires the use of Python version 2.6 or higher, but does not support Python 3.

Single or double quote characters (respectively, ' or ") can be used around option values. In fact, quotes are required to set some options values correctly, such as values with whitespace. For example, to specify the event types Create DB and Drop DB for the --event-type option, the following syntax must be used: --event-type='Create DB,Drop DB' or --event-type="Create DB,Drop DB".
