Struct MultiHistogram

pub struct MultiHistogram { /* private fields */ }

Represents a vector of histograms with floating point values. Wrapper for HistogramVec type

Implementations

impl MultiHistogram

pub fn record_measure(&self, timer: SimpleTimer)

Stops the given timer and records the elapsed duration in seconds to the multi-histogram.

pub fn cancel_measure(&self, timer: SimpleTimer) -> f64

Stops the given timer and discards the measured duration in seconds and returns it.

pub fn name(&self) -> String

Returns the name of the histogram given at construction.

impl MultiHistogram

pub fn new( name: &str, description: &str, buckets: Vec<f64>, labels: &[&str], ) -> Result<Self>

Creates a new histogram with the given name, description and buckets. If no buckets are specified, they will be defined automatically. The +Inf bucket is always added automatically.

pub fn start_measure(&self, label_values: &[&str]) -> Result<SimpleTimer>

Starts a timer for a histogram with the given labels.

pub fn observe(&self, label_values: &[&str], value: f64)

Records a value observation to the histogram with the given labels.

pub fn get_sample_count(&self, label_values: &[&str]) -> Option<u64>

Get all samples count with given labels

pub fn get_sample_sum(&self, label_values: &[&str]) -> Option<f64>

Get all samples sum with given labels

pub fn labels(&self) -> Vec<&str>

Returns the labels of the counters given at construction.
