Prometheus 3.8.0 introduces a relabeling visualizer in its web UI that helps debug target relabeling configurations. The tool provides a step-by-step view showing how each relabeling rule affects discovered target labels, highlighting changes, additions, and deletions. Users can now easily identify where targets get incorrectly labeled or dropped by inspecting the sequential application of rules from initial discovery through final output.
