Histogram

Struct Histogram 

Source
pub struct Histogram {
    pub name: String,
    pub count: u64,
    pub sum_ns: u64,
    pub min_ns: u64,
    pub max_ns: u64,
    pub buckets: [u64; 11],
}
Expand description

Histogram-Primitive — exponentielle Buckets (Powers of 10) plus Sum/Count/Min/Max. Bewusst minimalistisch: kein hdrhistogram-Dep, sondern [u64; 10]-Buckets fuer 1ns..10s in 10x-Schritten.

Für volle p99/p999-Aufloesung kann der Konsument hdrhistogram als Sink-Sink benutzen — wir liefern hier nur das aggregat-frei summierbare Format, das OTLP Histogram direkt mappt.

Fields§

§name: String

Logischer Name (z.B. "dds.write.latency").

§count: u64

Anzahl aller Records.

§sum_ns: u64

Summe aller Records (in der Einheit; default: ns).

§min_ns: u64

Min-Wert.

§max_ns: u64

Max-Wert.

§buckets: [u64; 11]

Bucket-Counts: buckets[i] = wie viele Records <= 10^i ns. 10 Buckets fuer 1ns (10^0) bis 10s (10^10).

Implementations§

Source§

impl Histogram

Source

pub fn new(name: impl Into<String>) -> Self

Konstruktor mit Namen.

Source

pub fn record_ns(&mut self, ns: u64)

Misst einen Wert in Nanosekunden.

Source

pub fn mean_ns(&self) -> u64

Mittelwert in Nanosekunden, oder 0 wenn count=0.

Source

pub fn bucket_bounds() -> [u64; 11]

Bucket-Boundaries als Array — fuer OTLP-Export. bounds[i] ist der obere Cutoff von buckets[i] in Nanosekunden.

Source

pub fn reset(&mut self)

Reset auf leeren Zustand.
