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.
