6 pmdapostgresql - PostgreSQL database PMDA
7
9 pmdapostgresql is a Performance Co-Pilot PMDA which extracts live per‐
10 formance data from a running PostgreSQL database.
11
13 pmdapostgresql uses a configuration file from (in this order):
14 · /etc/pcpdbi.conf
15 · $PCP_PMDAS_DIR/postgresql/postgresql.conf
16 · ./postgresql.conf
17
18 This file can contain overridden values (Perl code) for the settings
19 listed at the start of pmdapostgresql.pl, for example:
20 · $database - database access method and database name, [default:
21 'dbi:Pg:dbname=postgres'] (see DBI(3) for details)
22 · $username - username to connect to the database [default: 'post‐
23 gres']
24 · $password - password to connect to the database [default: '']
25 · $os_user - operating system username (PMDA will run with the corre‐
26 sponding user id) [default: $username]
27
28 Once this is setup, you can access the names and values for the post‐
29 gresql performance metrics by doing the following as root:
30
31 # cd $PCP_PMDAS_DIR/postgresql
32 # ./Install
33
34 To uninstall, do the following as root:
35
36 # cd $PCP_PMDAS_DIR/postgresql
37 # ./Remove
38
39 pmdapostgresql is launched by pmcd(1) and should never be executed
40 directly. The Install and Remove scripts notify pmcd(1) when the agent
41 is installed or removed.

56 Environment variables with the prefix PCP_ are used to parameterize the
57 file and directory names used by PCP. On each installation, the file
58 /etc/pcp.conf contains the local values for these variables. The
59 $PCP_CONF variable may be used to specify an alternative configuration
60 file, as described in pcp.conf(5).
