this environment?
You can check column pg_stat_activity.client_addr if your pgbouncer and
the clients making direct connections are on different hosts.
Otherwise you can list pgbouncer's connections with SHOW SERVERS in the
admin console[1] and cross-check with pg_stat_activity. Columns
local_addr and local_port of SHOW SERVERS matches client_addr and
client_port in pg_stat_activity. The remaining connections in
pg_stat_activity should be from other clients and backends.
In addition to what Erik said, there is pgbouncer_fdw, which makes several pg_bouncer real time monitoring data available as foreign tables, so you can join pg_stat_activity with pgbouncer_servers
and draw conclusions.
