Enum KeyAgg 

pub enum KeyAgg {
    Min,
    Max,
    Avg,
    Last,
    First,
    Median,
    Stddev,
    Sum,
    Count,
    Rate,
    Span,
    Delta,
}

SRD-109 — the time-dimension aggregate a key-metric designation carries. MANDATORY on every designation: there are no implied aggregates, so rows: result_success (no qualifier) is a parse error naming this vocabulary. Defined over the stored samples of one instance within the row scope’s activation window — which, per the SRD-42 amendment, are last-write-wins point samples with PromQL semantics.

Variants

Min

Max

Avg

Last

First

Median

Stddev

Sum

Count

Rate

Derived: increase over the activation span, per second.

Span

Derived: the activation’s wall clock (family-less — span()).

Delta

Derived: last − first over the activation.

Implementations

impl KeyAgg

pub const VOCAB: &'static str = "min, max, avg, last, first, median, stddev, sum, count; \ derived: rate(F), span(), delta(F)"

The suggestion list every qualification error carries.
