Description
Proposal
We had a query to count all connections by machine, which we lost due to deprecation of the queries file. I am sure others would profit from this as well
pg_connections_by_machine:
query: "select count(*) as count, client_hostname from pg_stat_activity where client_hostname is not null group by client_hostname ;"
master: true
metrics:
- client_hostname:
usage: "LABEL"
description: "Name of connecting client"
- count:
usage: "GAUGE"
description: "Number of Connections"
If there is another easy solution for this which I am missing right now please tell me.
Regards,
Dennis

Research direction
Start with the existing PostgreSQL collector entry points and how query results become Prometheus metrics. Use the proposed pg_stat_activity query and metric descriptions as the target behavior. Done means the exporter exposes connection counts grouped by non-null client_hostname, with client_hostname as a label and count as a gauge.
