fix: update dashboards to use service instead of exported_service

[cloud-j-luna]

Summary by CodeRabbit

• Bug Fixes

  • Corrected dashboard queries and variables to use the proper metric label, ensuring service filters work reliably and panels (node health, request counts, RPS, status codes, node status) display accurate data across dashboards.

• Chores

  • Aligned metric label usage across dashboards for consistency with the current Prometheus schema and improved maintainability.

Walkthrough

Prometheus label selectors in two Grafana dashboards were updated to replace exported_service with service across panel queries and templating variable definitions/queries. No structural or control-flow changes were made; only metric label names in expressions and label_values queries were adjusted.

Changes

Cohort / File(s)	Summary of Changes
Grafana node drilldown dashboard deploy/grafana/provisioning/dashboards/node-drilldown.json	Replaced PromQL selectors and templating queries from exported_service="$service" to service="$service"; updated label_values from exported_service to service for variables (service, proxy_type, node).
Grafana overview dashboard deploy/grafana/provisioning/dashboards/overview.json	Switched PromQL selectors and templating variable queries from exported_service to service across panels (Healthy Nodes, RPS, Request Count, Status Codes, Node Status) and related label_values.

Poem

I hop through dashboards, ears held high,
Swapping labels as metrics fly.
exported_service, I bid adieu—
hello, service, clean and true.
With every query, neat and terse,
A rabbit’s tweak improves the verse.

Learning: Prometheus automatically adds the "exported_" prefix to labels to preserve original target labels and differentiate labels from different sources. When labels are defined in scrape configurations, they become available with the "exported_" prefix in metrics queries, which is why dashboards should use "exported_service" even when the scrape config defines "service".

Learning: Prometheus automatically prefixes labels defined in scrape configurations with "exported_" when they conflict with internal labels. For example, a "service" label in static_configs becomes "exported_service" in the actual metrics, which is why dashboards should query using "exported_service" even when the code or config uses "service".
