Aliased Type§

struct RelabeledGuardedHistogramVec<const N: usize> {
    relabel_threshold: MetricLevel,
    metric_level: MetricLevel,
    metric: LabelGuardedMetricVec<impl MetricVecBuilder<M = Histogram>, N>,
    relabel_num: usize,
}

Fields§

§relabel_threshold: MetricLevel§metric_level: MetricLevel§metric: LabelGuardedMetricVec<impl MetricVecBuilder<M = Histogram>, N>§relabel_num: usize

The first relabel_num labels will be relabeled to empty string

For example, if relabel_num is 1, and the input labels are ["actor_id", "fragment_id", "table_id"], when threshold is reached, the label values will be ["", "<original_fragment_id>", "<original_table_id>"].
