feat: add cluster_name and cluster_peer labels to Prometheus metrics#277
Merged
Conversation
Move cluster_name and cluster_peer from mev-boost relabel_configs to global external_labels so all metrics (charon, mev-boost) include these identity labels. Also add the missing sed substitutions in run.sh that were preventing the variables from being rendered.
