The core engine histograms ship with default bucket boundaries tuned for
typical serving workloads. The `--custom-histogram-buckets` option replaces
the boundaries of one or more bucket families. Use it, for example, to track
sub-300ms latency SLOs with the request-phase histograms, whose smallest
default boundary is 0.3s.
