I thik both release-6.0 and master include the metric. Try "conflictDetectDurationHis"?

➜ gco release-6.0
Switched to branch 'release-6.0'
Your branch is behind 'origin/release-6.0' by 8 commits, and can be fast-forwarded.
  (use "git pull" to update your local branch)

➜ grep -Rn conflictDetectDurationHis cdc
cdc/sink/metrics.go:52: conflictDetectDurationHis = prometheus.NewHistogramVec(
cdc/sink/metrics.go:113:        registry.MustRegister(conflictDetectDurationHis)
cdc/sink/mysql.go:173:  metricConflictDetectDurationHis := conflictDetectDurationHis.

➜ gco master
