Metrics Exporter for vise

Documentation:

This crate provides a simple Prometheus metrics exporter for metrics defined using vise. It is based on the hyper library and supports both pull-based and push-based communication with Prometheus.

Usage

Add this to your Crate.toml:

[dependencies]
vise-exporter = "0.3.1"

An exporter can be initialized from a metrics Registry:

use tokio::sync::watch;

use vise_exporter::MetricsExporter;

async fn my_app() {
    let (shutdown_sender, mut shutdown_receiver) = watch::channel(());
    let exporter = MetricsExporter::default()
        .with_graceful_shutdown(async move {
            shutdown_receiver.changed().await.ok();
        });
    let bind_address = "0.0.0.0:3312".parse().unwrap();
    tokio::spawn(exporter.start(bind_address));

    // Then, once the app is shutting down:
    shutdown_sender.send_replace(());
}
