NAME

       pmdapostgresql - PostgreSQL database PMDA

DESCRIPTION

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

INSTALLATION

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

       •   /etc/pcpdbi.conf

       •   $PCP_PMDAS_DIR/postgresql/postgresql.conf

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

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

       •   database username

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

               # cd $PCP_PMDAS_DIR/postgresql
               # ./Install

       If you want to undo the installation, do the following as root:

               # cd $PCP_PMDAS_DIR/postgresql
               # ./Remove

       pmdapostgresql 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.
