Type Alias RelabeledHistogramVec

pub type RelabeledHistogramVec = RelabeledMetricVec<HistogramVec>;

Aliased Type§

struct RelabeledHistogramVec {
    relabel_threshold: MetricLevel,
    metric_level: MetricLevel,
    metric: MetricVec<HistogramVecBuilder>,
    relabel_num: usize,
}

Fields§

§relabel_threshold: MetricLevel§metric_level: MetricLevel§metric: MetricVec<HistogramVecBuilder>§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>"].
