[shutao917]

hi, i run exporter in docker,with DATA_SOURCE_NAME= postgresql://user:[email protected]:5432/postgres?sslmode=disable,postgresql://user:[email protected]:5432/postgres?sslmode=disable but the exporter just return one "pg_up{} 1" metric exception is: pg_up{server:"postgres-single.postgresql:5432"} 1 pg_up{server:"postgres-single.postgresql-2:5432"} 1

I have the same issue. I checked previous versions and the last one correctly working 0.5.1. On servers with many sources, rolled back to 0.5.1. pg_up is an important metric for a trigger as pg_up != 10.

Same here, proposed idea about labels in pg_up metrics seems sufficient. @wrouesnel what do You think?

[timown]

Same here, would expect server label here

@SuperQ do you have any plan to support "server" label for pg_up? https://awesome-prometheus-alerts.grep.to/rules#rule-postgresql-1-1 for multi instance availability alert
