NAME

       pmdadbping - database response time and availability PMDA

DESCRIPTION

       pmdadbping is a database response time measurement PMDA.

       pmdadbping runs dbprobe(1), and exports the performance measurements it makes available as
       PCP metrics.

       dbprobe(1) should be configured to use the type of DBI appropriate for the local database,
       which  includes:  RDBMS flavour, user/password, delay between "ping" requests, and the SQL
       statement to use.

INSTALLATION

       Configure dbprobe(1) - it uses a configuration file from (in this order):

       •   /etc/pcpdbi.conf

       •   $PCP_PMDAS_DIR/dbping/dbprobe.conf

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

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

       •   database user name

       •   database pass word

       •   SQL statement to measure (probe)

       •   delay between probes

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

           # cd $PCP_PMDAS_DIR/dbping
           # ./Install

       To uninstall, the following must be done as root:

           # cd $PCP_PMDAS_DIR/dbping
           # ./Remove

       pmdadbping 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.

FILES

       $PCP_PMDAS_DIR/dbping/dbprobe.conf
           probe configuration file for dbprobe(1), used indirectly by pmdadbping

       $PCP_PMDAS_DIR/dbping/Install
           installation script for the pmdadbping agent

       $PCP_PMDAS_DIR/dbping/Remove
           undo installation script for the pmdadbping agent

       $PCP_LOG_DIR/pmcd/dbping.log
           default log file for error messages from pmdadbping

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).
