Counter metrics like chunks.exported.count are monotonically increasing. Add mode=delta query parameter to the agent metrics API that computes per-bucket deltas server-side using ClickHouse lag() window function: max(value) per bucket, then greatest(0, current - previous) to get the increase per period with counter-reset handling. The chunks exported/dropped charts now show throughput per bucket instead of the ever-increasing cumulative total. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
