NAME
mysqlprocgrep - Search Server Process Lists
SYNOPSIS
mysqlprocgrep [options]
DESCRIPTION
This utility scans the process lists for the servers specified using instances of the --server option and
selects those that match the conditions specified using the --age and --match-xxx options. For a process
to match, all conditions given must match. The utility then either prints the selected processes (the
default) or executes certain actions on them.
If no --age or --match-xxx options are given, the utility selects all processes.
The --match-xxx options correspond to the columns in the INFORMATION_SCHEMA.PROCESSLIST table. For
example, --match-command specifies a matching condition for PROCESSLIST.COMMAND column values. There is
no --match-time option. To specify a condition based on process time, use --age.
Processes that can be seen and killed are subject to whether the account used to connect to the server
has the PROCESS and SUPER privileges. Without PROCESS, the account cannot see processes belonging to
other accounts Without SUPER, the account cannot kill processes belonging to other accounts
To specify how to display output, use one of the following values with the --format option:
• grid (default)
Display output in grid or table format like that of the mysql monitor.
• csv
Display output in comma-separated values format.
• tab
Display output in tab-separated format.
• vertical
Display output in single-column format like that of the \G command for the mysql monitor.
Options
mysqlprocgrep accepts the following command-line options:
• --help
Display a help message and exit.
• --age=<time>
Select only processes that have been in the current state more than a given time. The time value can
be specified in two formats: either using the hh:mm:ss format, with hours and minutes optional, or as
a sequence of numbers with a suffix giving the period size.
The permitted suffixes are s (second), m (minute), h (hour), d (day), and w (week). For example,
4h15m mean 4 hours and 15 minutes.
For both formats, the specification can optionally be preceded by + or -, where + means older than
the given time, and - means younger than the given time.
• --format=<format>, -f<format>
Specify the output display format. Permitted format values are grid, csv, tab, and vertical. The
default is grid.
• --kill-connection
Kill the connection for all matching processes (like the KILL CONNECTION statement).
• --kill-query
Kill the query for all matching processes (like the KILL QUERY statement).
• --match-command=<pattern>
Match all processes where the Command field matches the pattern.
• --match-db=<pattern>
Match all processes where the Db field matches the pattern.
• --match-host=<pattern>
Match all processes where the Host field matches the pattern.
• --match-info=<pattern>
Match all processes where the Info field matches the pattern.
• --match-state=<pattern>
Match all processes where the State field matches the pattern.
• --match-user=<pattern>
Match all processes where the User field matches the pattern.
• --print
Print information about the matching processes. This is the default if no --kill-connection or
--kill-query option is given. If a kill option is given, --print prints information about the
processes before killing them.
• --regexp, --basic-regexp, -G
Perform pattern matches using the REGEXP operator. The default is to use LIKE for matching. This
affects the --match-xxx options.
• --server=<source>
Connection information for a server to search in the format:
<user>[:<passwd>]@<host>[:<port>][:<socket>] or <login-path>[:<port>][:<socket>]. Use this option
multiple times to search multiple servers.
• --sql, --print-sql, -Q
Instead of displaying the selected processes, emit the SELECT statement that retrieves information
about them. If the --kill-connection or --kill-query option is given, the utility generates a stored
procedure named kill_processes() for killing the queries rather than a SELECT statement.
• --sql-body
Like --sql, but produces the output as the body of a stored procedure without the CREATE PROCEDURE
part of the definition. This could be used, for example, to generate an event for the server Event
Manager.
When used with a kill option, code for killing the matching queries is generated. Note that it is not
possible to execute the emitted code unless it is put in a stored routine, event, or trigger. For
example, the following code could be generated to kill all idle connections for user www-data:
$ mysqlprocgrep --kill-connection --sql-body \
> --match-user=www-data --match-state=sleep
DECLARE kill_done INT;
DECLARE kill_cursor CURSOR FOR
SELECT
Id, User, Host, Db, Command, Time, State, Info
FROM
INFORMATION_SCHEMA.PROCESSLIST
WHERE
user LIKE 'www-data'
AND
State LIKE 'sleep'
OPEN kill_cursor;
BEGIN
DECLARE id BIGINT;
DECLARE EXIT HANDLER FOR NOT FOUND SET kill_done = 1;
kill_loop: LOOP
FETCH kill_cursor INTO id;
KILL CONNECTION id;
END LOOP kill_loop;
END;
CLOSE kill_cursor;
• --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
For the --format option, the permitted values are not case sensitive. In addition, values may be
specified as any unambiguous prefix of a valid value. For example, --format=g specifies the grid format.
An error occurs if a prefix matches more than one valid value.
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).
EXAMPLES
For each example, assume that the root user on localhost has sufficient privileges to kill queries and
connections.
Kill all queries created by user mats that are younger than 1 minute:
mysqlprocgrep --server=root@localhost \
--match-user=mats --age=-1m --kill-query
Kill all connections that have been idle for more than 1 hour:
mysqlprocgrep --server=root@localhost \
--match-command=sleep --age=1h --kill-connection
