Patroni Exporter broken dashboard panels

[Deezzir]

Steps to reproduce

1. Deploy the charm.
2. Open the Patroni Grafana dashboard.

Expected behaviour

Patroni panels (xlog_location, etc.) should render correctly.

Actual behaviour

Panels show no data. Prometheus and the OpenMetrics standard now automatically append _total to the name of any metric with the TYPE counter. The dashboard queries still use the legacy metric names.

Versions

Juju CLI: N/A
Juju agent: N/A
Charm revision: N/A
LXD: N/A

Log output

Juju debug log: N/A

Additional context

Proposal:
Patch the Grafana dashboard JSON to comply with the OpenMetrics standard by updating the following queries:

• patroni_xlog_location -> patroni_xlog_location_total
• patroni_xlog_received_location -> patroni_xlog_received_location_total
• patroni_xlog_replayed_location -> patroni_xlog_replayed_location_total
