pub fn gauge(name: String) -> Gauge
Create a gauge to monitor both incrementing and decrementing of a statistic
Example
use metrical::gauge; use std::thread::JoinHandle; struct Threader{ threads: Vec<JoinHandle<()>> } impl Threader { pub fn add_resource(&mut self) { let mut gauge = gauge("NumThreadsInUse".to_owned()); gauge.increment(1); self.threads.push(std::thread::spawn(|| println!("This does nothing...") )); } pub fn terminate_resource(&mut self) { let mut gauge = gauge("NumThreadsInUse".to_owned()); gauge.decrement(1); self.threads.pop().map(|thread| thread.join()); } }
