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
· ./postgresql.conf

This file can contain overridden values (Perl code) for the settings listed at the start
of pmdapostgresql.pl, for example:
· $database - database access method and database name, [default:
'dbi:Pg:dbname=postgres'] (see DBI(3) for details)
· $username - username to connect to the database [default: 'postgres']
· $password - password to connect to the database [default: '']
· $os_user - operating system username (PMDA will run with the corresponding user id)
[default: $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

To uninstall, 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.
