Struct CacheSizeMetrics 

pub struct CacheSizeMetrics {
    gauges: IntGaugeVec,
    sources: Arc<Mutex<Vec<CacheSizeSource>>>,
}

Cache byte metrics combining manually maintained gauges and sampled cache weights. Sampling does not force backend maintenance or include pending loader values.

Fields

gauges: IntGaugeVec

sources: Arc<Mutex<Vec<CacheSizeSource>>>

Implementations

impl CacheSizeMetrics

pub fn new(opts: Opts, labels: &[&str]) -> Result<Self>

Creates an unregistered collector. Register a clone with the caller’s registry.

pub fn gauges(&self) -> &IntGaugeVec

Returns the backing gauges for callers retaining manual accounting.

pub fn with_label_values(&self, labels: &[&str]) -> IntGauge

Returns a manually maintained gauge for existing non-cache accounting.

pub fn bind(&self, labels: &[&str]) -> CacheSizeMetric

Binds labels for sampled cache weights. Instances sharing labels are summed.
