Access PgBouncer statistics
PgBouncer is used at Aiven for connection pooling.
Get PgBouncer URL
PgBouncer URL can be checked under Pools in Aiven Console
your Aiven for PostgreSQL® service's page > Pools view (available from the sidebar). Alternatively, it can be extracted via Aiven Command Line interface, using jq to parse the JSON response.
Execute the following command replacing the INSTANCE_NAME parameter
with the name of your instance:
avn service get INSTANCE_NAME --project PROJECT_NAME --json | jq -r '.connection_info.pgbouncer'
The output will be similar to the below:
postgres://avnadmin:xxxxxxxxxxx@demo-pg-dev-advocates.aivencloud.com:13040/pgbouncer?sslmode=require
Connect to PgBouncer
To connect to PgBouncer, use the extracted URL:
psql 'EXTRACTED_PGBOUNCER_URL'
Access statistics
Enable the expanded display by running:
pgbouncer=# \x
Show the statistics by running:
pgbouncer=# SHOW STATS;
Depending on the load of your database, the output will be similar to:
database | total_xact_count | total_query_count | total_received | total_sent | total_xact_time | total_query_time | total_wait_time | avg_xact_count | avg_query_count | avg_recv | avg_sent | avg_xact_time | avg_query_time | avg_wait_time

Run SHOW HELP to see all available commands. Only read-only access is
available, as PgBouncer pools are automatically managed by Aiven.
