NAME

       mysqlreport - Makes a friendly report of important MySQL status values

SYNTAX

       mysqlreport [options]

DESCRIPTION

       mysqlreport makes a friendly report of important MySQL status values. Actually, it makes a
       friendly report of nearly every status value from SHOW STATUS.  Unlike SHOW  STATUS  which
       simply  dumps  over  100  values  to  screen  in one long list, mysqlreport interprets and
       formats the values and presents the basic values  and  many  more  inferred  values  in  a
       human-readable  format. Numerous example reports are available at the mysqlreport web page
       at http://hackmysql.com/mysqlreport.

       The benefit of mysqlreport is that it allows you to very  quickly  see  a  wide  array  of
       performance  indicators  for your MySQL server which would otherwise need to be calculated
       by hand from all the various SHOW STATUS values. For example, the Index Read Ratio  is  an
       important  value but it's not present in SHOW STATUS; it's an inferred value (the ratio of
       Key_reads to Key_read_requests).

       This documentation outlines all the command line options in  mysqlreport,  most  of  which
       control  which  reports are printed. This document does not address how to interpret these
       reports; that topic is covered in the  document  Guide  To  Understanding  mysqlreport  at
       http://hackmysql.com/mysqlreportguide.

OPTIONS

       Technically,  command  line  options  are in the form --option, but -option works too. All
       options can be abbreviated if the abbreviation is unique. For example, option  --host  can
       be abbreviated --ho but not --h because --h is ambiguous: it could mean --host or --help.

       --help Output help information and exit.

       --user USER

       --password
              As  of  version  2.3  --password  can  take  the  password on the command line like
              "--password FOO". Using --password alone without giving a password on  the  command
              line causes mysqlreport to prompt for a password.

       --host ADDRESS

       --port PORT

       --socket SOCKET

       --no-mycnf
              --no-mycnf makes mysqlreport not read ~/.my.cnf which it does by default otherwise.
              --user and --password always override values from ~/.my.cnf.

       --dtq  Print Distribution of Total Queries (DTQ) report (under Total in Questions report).
              Queries  (or Questions) can be divided into four main areas: DMS (see --dms below),
              Com_   (see   --com   below),   COM_QUIT   (see   COM_QUIT   and    Questions    at
              http://hackmysql.com/com_quit),  and  Unknown. --dtq lists the number of queries in
              each of these areas in descending order.

       --dms  Print Data Manipulation Statements (DMS) report (under DMS  in  Questions  report).
              DMS  are  those  from  the MySQL manual section 13.2. Data Manipulation Statements.
              (Currently,  mysqlreport  considers  only  SELECT,  INSERT,  REPLACE,  UPDATE,  and
              DELETE.) Each DMS is listed in descending order by count.

       --com N
              Print  top N number of non-DMS Com_ status values in descending order (after DMS in
              Questions report). If N is not given,  default  is  3.  Such  non-DMS  Com_  values
              include Com_change_db, Com_show_tables, Com_rollback, etc.

       --sas  Print  report  for  Select_  and  Sort_ status values (after Questions report). See
              MySQL Select and Sort Status Variables at http://hackmysql.com/selectandsort.

       --tab  Print Threads, Aborted, and Bytes status reports (after Created temp report). As of
              mysqlreport v2.3 the Threads report reports on all Threads_ status values.

       --qcache
              Print Query Cache report.

       --all  Equivalent  to  "--dtq --dms --com 3 --sas --qcache".  (Notice --tab is not invoked
              by --all.)

       --infile FILE
              Instead of getting SHOW STATUS values from MySQL, read values from  FILE.  FILE  is
              often  a  copy  of the output of SHOW STATUS including formatting characters (|, +,
              -).  mysqlreport expects FILE to have the format " value number "  where  value  is
              only  alpha and underscore characters (A-Z and _) and number is a positive integer.
              Anything before, between, or after value and number is  ignored.  mysqlreport  also
              needs  the following MySQL server variables: version, table_cache, max_connections,
              key_buffer_size, query_cache_size. These values can be specified in INFILE  in  the
              format  "name = value" where name is one of the aforementioned server variables and
              value is a positive integer with or without a trailing M and possible periods  (for
              version).  For  example,  to specify an 18M key_buffer_size: key_buffer_size = 18M.
              Or, a 256 table_cache: table_cache = 256. The M implies Megabytes not  million,  so
              18M  means  18,874,368  not 18,000,000. If these server variables are not specified
              the following defaults are used (respectively) which may cause strange values to be
              reported: 0.0.0, 64, 100, 8M, 0.

       --outfile FILE
              After  printing  the  report  to  screen, print the report to FILE too. Internally,
              mysqlreport always writes the report to a temp file first: /tmp/mysqlreport.PID  on
              *nix,  c:sqlreport.PID  on Windows (PID is the script's process ID). Then it prints
              the temp file to screen. Then if --outfile is specified, the temp file is copied to
              OUTFILE. After --email (below), the temp file is deleted.

       --email ADDRESS
              After  printing  the  report  to  screen,  email the report to ADDRESS. This option
              requires  sendmail  in  /usr/sbin/,  therefore  it  does  not  work   on   Windows.
              /usr/sbin/sendmail  can  be  a  sym  link  to  qmail,  for example, or any MTA that
              emulates sendmail's -t command line  option  and  operation.  The  FROM:  field  is
              "mysqlreport", SUBJECT: is "MySQL status report".

       --flush-status
              Execute  a  "FLUSH  STATUS;"  after  generating  the  reports.   If you do not have
              permissions in MySQL to do this an error  from  DBD::MariaDB::st  will  be  printed
              after the reports.
