pmdapostgresql — PostgreSQL database PMDA


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

Many of the staticstics available from a PostgreSQL server may not be enabled by default. Refer to the online documentation at which describes each of the available parameters related to statistics collection and how to enable them.


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

This file can contain overridden values (Perl code) for the settings listed at the start of, for example:

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

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).
