PMDADBPING(1)

NAME
pmdadbping - database response time and availability PMDA

DESCRIPTION
Simple database response time measurement PMDA. dbprobe.pl(1) should be configured to use the type of DBI appropriate for your database, which includes: RDBMS flavour, user/password, delay between "ping" requests, and the SQL statement to use. pmdadbping runs dbprobe.pl(1), and exports the performance measurements it makes available as PCP metrics.

INSTALLATION
Configure dbprobe.pl(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

If you want to undo the installation, do the following 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.
