PgBouncer Metrics Exporter Configuration

The PgBouncer Metrics Exporter exposes metrics such as the number of active connections, connections waiting in the queue, resource usage by PgBouncer, among others. This information is important to adjust the pooling operation and ensure that the environment is responding efficiently to client requests.

Through this configuration option, it is possible to specify the exposure port for PgBouncer metrics to be collected by Prometheus.

PgBouncer Exporter Configuration​

  1. Select the PgSmart Agent or register a new one.

  2. Select the PgBouncer Metrics Exporter.

  3. Add the Connection Pool Management instance(s).

    warning

    This metrics exporter requires the pre-configuration of the _ignore_startup_parameters_ parameter with the value _extra_float_digits_ for each PgBouncer instance.

    This configuration can be done by PgSmart itself through the Connection Pool service configuration option.

    This configuration is necessary for the connection driver to ignore certain parameters when initializing the connection.

    It is important to note that the PgBouncer metrics exporter will be configured by PgSmart regardless of this configuration. However, the metrics export will only start after the _ignore_startup_parameters_ parameter is configured.

    3.1. Provide the connection port for Connection Pool Management.

    3.2. Provide the user for Connection Pool Management.

    3.3. Provide the password for the Connection Pool Management user.

    3.4. Confirm if you want to add another Connection Pool Management instance.

    3.5. Provide the metrics exposure port and web interface.
