Feat: kupo dolos checkpoint stale alert - #65
Merged
Conversation
…panel Mirrors the Kupo checkpoint-stale work for the Dolos-backed Kupo deployment. Adds a 'Kupo (Dolos) checkpoint is stale' alert that fires when a connected Dolos-backed Kupo instance's most recent checkpoint (kupo_most_recent_checkpoint) stops advancing for 15m, catching wedged Kupo<->Dolos chain-sync sessions that report connection_status=connected but serve a stale index. Notifies #infra-alerts. Adds a matching 'Checkpoint Advancement (changes / 15m)' timeseries panel under a new 'Checkpoint Health' row on the Cardano Kupo (Dolos) dashboard.

The grafana_alerts module existed but was never instantiated, so the alert JSON files under grafana/alerts/ (including the Kupo and Kupo-Dolos checkpoint-stale rules) were never deployed by terraform apply. Adds grafana-alerts.tf to instantiate the module for each grafana.alerts entry in config.yaml, using the existing folder UIDs and the shared data source UID map.
Also fixes the module's fileset/templatefile path from ${path.root}/../${var.local_directory} to ${path.root}/${var.local_directory}, matching the working grafana_dashboard module (path.root is the repo root, so the ../ pointed outside the repo and matched zero files).
