Crate metrics_printer[−][src]
This crate provides you with a metrics recorder that can print all metrics to a target of your choice in regular intervals.
It uses a thread to print, so it doesn’t interfere with other threads’ work directly.
Custom printing targets (e.g., logging frameworks) can be provided via the simple Printer trait, while default implementations for stdout and stderr are provided.
Example
use metrics::*; use metrics_printer::*; PrintRecorder::default().install().unwrap(); register_counter!("test.counter"); for _i in 0..300 { increment_counter!("test.counter"); std::thread::sleep(Duration::from_millis(10)); }
