NAME¶
mysqlserverinfo - Display Common Diagnostic Information from a ServerSYNOPSIS¶
mysqlserverinfo [options]
db1 [:db2] ...
DESCRIPTION¶
This utility displays critical information about a server for use in diagnosing problems. The information displayed includes the following:•Server connection information
•Server version number
•Data directory path name
•Base directory path name
•Plugin directory path name
•Configuration file location and name
•Current binary log coordinates (file name and
position)
•Current relay log coordinates (file name and
position)
This utility can be used to see the diagnostic information for servers that are
running or offline. If you want to see information about an offline server,
the utility starts the server in read-only mode. In this case, you must
specify the --basedir, --datadir, and --start options to
prevent the utility from starting an offline server accidentally. Note: Be
sure to consider the ramifications of starting an offline server on the error
and similar logs. It is best to save this information prior to running this
utility.
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.
To turn off the headers for csv or tab display format, specify the
--no-headers option.
To see the common default settings for the local server's configuration file,
use the --show-defaults option. This option reads the configuration
file on the machine where the utility is run, not the machine for the host
that the --server option specifies.
To run the utility against several servers, specify the --server option
multiple times. In this case, the utility attempts to connect to each server
and read the information.
To see the MySQL servers running on the local machine, use the
--show-servers option. This shows all the servers with their process ID
and data directory. On Windows, the utility shows only the process ID and
port.
OPTIONS mysqlserverinfo accepts the following command-line options:
•--help
Display a help message and exit.
•--basedir=<basedir>
The base directory for the server. This option is required for starting an
offline server.
Is also used to access server tools, such as my_print_defaults that is required
to read the login-path values from the login configuration file
(.mylogin.cnf).
•--datadir=<datadir>
The data directory for the server. This option is required for starting an
offline server.
•--format=<format>, -f<format>
Specify the output display format. Permitted format values are grid,
csv, tab, and vertical. The default is grid.
•--no-headers, -h
Do not display column headers. This option applies only for csv and
tab output.
•--port-range=<start:end>
The port range to check for finding running servers. This option applies only to
Windows and is ignored unless --show-servers is given. The default
range is 3306:3333.
•--server=<server>
Connection information for a server in the format: <
user>[:<passwd>]@<
host>[:<port>][:< socket>] or
<login-path>[:< port>][:<socket>]. Use
this option multiple times to see information for multiple servers.
•--show-defaults, -d
Display default settings for mysqld from the local configuration file. It
uses my_print_defaults to obtain the options.
•--show-servers
Display information about servers running on the local host. The utility
examines the host process list to determine which servers are running.
•--start, -s
Start the server in read-only mode if it is offline. With this option, you must
also give the --basedir and --datadir options.
•--start-timeout
Number of seconds to wait for the server to be online when started in read-only
mode using the --start option. The default value is 10 seconds.
The --start-timeout option is available as of MySQL Utilities 1.2.4 /
1.3.3.
•--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.
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 To display the server information for the local server and the settings for mysqld in the configuration file with the output in a vertical list, use this command:
$ mysqlserverinfo --server=root:pass@localhost -d --format=vertical # Source on localhost: ... connected. ************************* 1. row ************************* server: localhost:3306 version: 5.1.50-log datadir: /usr/local/mysql/data/ basedir: /usr/local/mysql-5.1.50-osx10.6-x86_64/ plugin_dir: /usr/local/mysql-5.1.50-osx10.6-x86_64/lib/plugin config_file: /etc/my.cnf binary_log: my_log.000068 binary_log_pos: 212383 relay_log: None relay_log_pos: None 1 rows. Defaults for server localhost:3306 --port=3306 --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --server_id=5 --log-bin=my_log --general_log --slow_query_log --innodb_data_file_path=ibdata1:778M;ibdata2:50M:autoextend #...done.
