Access PgBouncer statistics

PgBouncer is used at Aiven for Connection pooling.

Get PgBouncer URL

PgBouncer URL can be seen under Pools in the PostgreSQL® service web interface. Alternatively it can be extracted via Aiven Command Line interface, using jq (https://stedolan.github.io/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 --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

Connect to PgBouncer using the URL extracted above and show the statistics with:

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

Tip

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