NAME
mysqlserverinfo - Display Common Diagnostic Information from a Server
SYNOPSIS
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 (filename and position)
• Current relay log coordinates (filename 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 client command-line tool.
• 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 client command-line
tool.
To turn off the headers for grid, 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.PP mysqlserverinfo accepts the following command-line options:
• --help
Display a help message and exit.
• --license
Display license information 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 grid, 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. Use this option multiple times to see information for multiple
servers.
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-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.
• --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).
• --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.PP 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:
shell> mysqlserverinfo --server=root:pass@localhost -d --format=vertical
