NAME         top

       pmdadbping - database response time and availability PMDA

DESCRIPTION         top

       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         top

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

       •   /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, 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         top

           probe configuration file for dbprobe(1), used indirectly by

           installation script for the pmdadbping agent

           undo installation script for the pmdadbping agent

           default log file for error messages from pmdadbping


       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
