pub trait GaugeMetric {
// Required method
fn name(&self) -> &'static str;
}Expand description
A metric for capturing gauges.
Gauge values are an instantaneous measurement of a value determined by the client. They do not change unless changed by the client. Examples include things like load average or how many connections are active.
§Example
use relay_statsd::{metric, GaugeMetric};
struct QueueSize;
impl GaugeMetric for QueueSize {
fn name(&self) -> &'static str {
"queue_size"
}
}
let queue = VecDeque::new();
// a simple gauge value
metric!(gauge(QueueSize) = queue.len() as u64);
// a gauge with tags
metric!(
gauge(QueueSize) = queue.len() as u64,
server = "server1",
host = "host1"
);
