Struct KeyMetric 

pub struct KeyMetric {
    pub column: String,
    pub agg: KeyAgg,
    pub family: String,
}

SRD-109 — one key-metric designation on an execution node: column: agg(family). Designating key metrics both names the node’s measurables and attaches the node to the table row of its nearest enclosing anchor (or the spine). family is empty for the family-less span().

Fields

column: String

agg: KeyAgg

family: String
