Hello, I'm creating a dashboard database using Postgres Exporter, Prometheus, and Grafana. But it seems the database is not connected to the grafana dashboard because there is no data and the database not appear on dashboard. Then i check Prometheus, there is no query for pg_stat?
The only queries available are pg_exporter_last_scrape_duration_seconds, pg_up, pg_exporter_last_scrape_error, pg_exporter_scrapes_total.
So basically, I'm missing some metrics from the PostgreSQL exporter.
Then i check debugs logs and showing like this
Can anyone help me on how to resolve this? Thank you
Your connection was refused, so fix your credetials for connection. Also check for firewall, hba.conf setting, etc.

You are missing your config file, which should not be deal breaker
