NAME

       pmdamysql - MySQL database PMDA

DESCRIPTION

       pmdamysql  is  a  Performance  Co-Pilot  PMDA  which  extracts live performance data from a running MySQL
       database.

INSTALLATION

       pmdamysql uses a configuration file from (in this order):

       •   /etc/pcpdbi.conf

       •   $PCP_PMDAS_DIR/mysql/mysql.conf

       This file can contain overridden values (Perl code) for the settings listed at the start of pmdamysql.pl,
       namely:

       •   database name (see DBI(3) for details)

       •   database username

       Once this is setup, you can access the names and values for the mysql performance metrics  by  doing  the
       following as root:

             # cd $PCP_PMDAS_DIR/mysql
             # ./Install

       To uninstall, do the following as root:

             # cd $PCP_PMDAS_DIR/mysql
             # ./Remove

       pmdamysql  is  launched  by pmcd(1) and should never be executed directly. The Install and Remove scripts
       notify pmcd(1) when the agent is installed or removed.

Binary Status values in text

       Some of the status values are in the form of YES/NO or ON/OFF.

       Since these cannot be intepreted by tools like pmie(1), they have been duplicated with a  _num  extension
       and the values of 1 (YES/ON) or 0 (NO/OFF).

   Eg:
       •   mysql.slave_status.slave_io_running

       •   mysql.slave_status.slave_io_running_num

           installation script for the pmdamysql agent

PCP ENVIRONMENT

       Environment  variables with the prefix PCP_ are used to parameterize the file and directory names used by
       PCP. On each installation, the file /etc/pcp.conf contains the local values  for  these  variables.   The
       $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).
