PostgreSQL Server Exporter
Note: Available since Omnibus GitLab 8.17. For installations from source you will have to install and configure it yourself.
The PostgreSQL Server Exporter allows you to export various PostgreSQL metrics.
To enable the PostgreSQL Server Exporter:
postgres_exporter['enable'] = true
If PostgreSQL Server Exporter is configured on a separate node, make sure that the local
address is listed in
trust_auth_cidr_addresses or the
exporter will not be able to connect to the database.
- Save the file and reconfigure GitLab for the changes to take effect.
Prometheus will now automatically begin collecting performance data from
the PostgreSQL Server Exporter exposed under
In most cases, PostgreSQL Server Exporter will work with the defaults and you should not need to change anything.
To further customize the PostgreSQL Server Exporter, use the following configuration options:
postgres_exporter['dbname'] = 'pgbouncer' # The name of the database to connect to. postgres_exporter['user'] = 'gitlab-psql' # The user to sign in as. postgres_exporter['password'] = '' # The user's password. postgres_exporter['host'] = 'localhost' # The host to connect to. Values that start with '/' are for unix domain sockets (default is 'localhost'). postgres_exporter['port'] = 5432 # The port to bind to (default is '5432'). postgres_exporter['sslmode'] = 'require' # Whether or not to use SSL. Valid options are: # 'disable' (no SSL), # 'require' (always use SSL and skip verification, this is the default value), # 'verify-ca' (always use SSL and verify that the certificate presented by the server was signed by a trusted CA), # 'verify-full' (always use SSL and verify that the certification presented by the server was signed by a trusted CA and the server host name matches the one in the certificate). postgres_exporter['fallback_application_name'] = '' # An application_name to fall back to if one isn't provided. postgres_exporter['connect_timeout'] = '' # Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely. postgres_exporter['sslcert'] = 'ssl.crt' # Cert file location. The file must contain PEM encoded data. postgres_exporter['sslkey'] = 'ssl.key' # Key file location. The file must contain PEM encoded data. postgres_exporter['sslrootcert'] = 'ssl-root.crt' # The location of the root certificate file. The file must contain PEM encoded data.
