How to configure pgbouncer source?

[klonuo]

Hi,

I run one of the databases under pgbouncer, and set in pgwatch sources postgresql://klo:[email protected]:6432/isd with type pgbouncer and selected corresponded preset.

If I run:

pgwatch --sources=postgresql://pgwatch:pgwatchadmin@localhost:5432/pgwatch --sink=postgresql://pgwatch:pgwatchadmin@localhost:5432/pgwatch_metrics

I get:

2025-09-04 05:29:45.903 [ERROR] [database:isd] [err:failed to connect to `user=klo database=isd`:
        192.168.100.2:6432 (192.168.100.2): dial error: dial tcp 192.168.100.2:6432: connect: connection refused

User "klo" is set as admin and stats user in pgbouncer. I can access pgbouncer database with psql -U klo pgbouncer and SHOW STATS prints the results as expected.

Anyone have a suggestion how to set pgwatch with pgbouncer?

Why you set isd database then in the connection string? It must be pgbouncer:

postgresql://klo:[email protected]:6432/pgbouncer

Ah so to reference the db itself...
I just did that and I get the same result:

[ERROR] [database:pgbouncer] [err:failed to connect to `user=klo database=pgbouncer`

I can connect to pgbouncer db with psql -p 6432 pgbouncer afterwhich I'm asked for password and then headed:

klo@Asus:~ $ psql -p 6432 pgbouncer
Password for user klo:
pgbouncer=# show help;

while in sources I've set

postgresql://klo:[email protected]:6432/pgbouncer

Ok great thanks @pashagolub for pointing in the right direction.

Besides wrong database, I used lan network address as for other database sources in pgwatch, but after setting localhost instead lan address everything works now :)
