fix(grafana): remove obsolete Kupo Sync Delta rule - #73
Merged
Conversation
The Kupo Sync Delta alert queried kupo_most_recent_node_tip - kupo_most_recent_checkpoint in namespace ftr-kupo-v1, which was decommissioned when Kupo moved to the Dolos-backed proxies (namespace dolos). kupo_most_recent_node_tip is no longer populated (NaN / no series) anywhere, so the rule only ever produced DatasourceNoData and cannot be salvaged by repointing the namespace. Checkpoint staleness for the Dolos-based Kupo is already covered by 'Kupo checkpoint is stale' and 'Kupo (Dolos) checkpoint is stale', so remove the dead sync-delta rule.
