PROGRAM:
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.
Use pmdapostgresql online using onworks.net services
