       pmdapostgresql - PostgreSQL database PMDA

DESCRIPTION         top

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

INSTALLATION         top

       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.

PCP ENVIRONMENT         top

       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 pcp.conf(5).
