    pub name: String,
    pub snapshots: Vec<(u64, String, f64)>,
    pub capacity: usize,
}

snapshots: Vec<(u64, String, f64)>

Collected metric snapshots: (timestamp_ns, metric_name, value).

capacity: usize

Maximum snapshots to keep.

Implementations

pub fn new(name: &str, capacity: usize) -> Self

Create a new monitor.

pub fn record(&mut self, metric: &str, value: f64)

Record a metric value.

pub fn latest(&self, metric: &str) -> Option<f64>

Get the most recent value for a metric.

pub fn avg(&self, metric: &str) -> f64

Average value for a metric.

pub fn count(&self, metric: &str) -> usize

Count of snapshots for a metric.
