Summary
Cardano node metrics update
In the new version of cardano-node the following metrics were removed:
• cardano_node_metrics_peers_connectedPeers_int
• cardano_node_metrics_Forge_adopted_int
We replaced these metrics with their current equivalents (peerSelection_, Forge_ + slotsMissedNum_int) to keep dashboards functional.
Grafana dashboard changes
• Replaced the Clock widget (not natively supported by Grafana by default) with a Stat panel using PromQL time() * 1000 and unit dateTimeAsIso to display the current time.
• Updated Grafana dashboard plugins to the latest supported versions.
Motivation
• Ensure compatibility of monitoring dashboards with the latest cardano-node version.
• Remove reliance on deprecated plugins (Clock) and switch to native PromQL/Grafana functionality.
• Keep dashboards up to date and avoid errors from missing metrics.
Notes
• Please verify dashboards after deployment to ensure new metrics map correctly to widgets.
• Backward compatibility with older cardano-node versions is not preserved.
