Prometheus Rust client library

Build Status docs.rs crates.io

This is the Rust client library for Prometheus. The main Structures and APIs are ported from Go client.

Usage

  • Add this to your Cargo.toml:

    [dependencies]
    prometheus = "0.2"
  • Add this to your crate in lib.rs:

    extern crate prometheus
  • Or enable nightly feature for better performance.

    [dependencies.prometheus]
    git = "https://github.com/pingcap/rust-prometheus.git"
    default-features = false
    features = ["nightly"]

Example

use prometheus::{Opts, Registry, Counter, TextEncoder, Encoder};

// Create a Counter.
let counter_opts = Opts::new("test_counter", "test counter help");
let counter = Counter::with_opts(counter_opts).unwrap();

// Create a Registry and register Counter. 
let r = Registry::new();
r.register(Box::new(counter.clone())).unwrap();

// Inc.
counter.inc();

// Gather the metrics.
let mut buffer = vec![];
let encoder = TextEncoder::new();
let metric_familys = r.gather();
encoder.encode(&metric_familys, &mut buffer).unwrap();

// Output to the standard output.
println!("{}", String::from_utf8(buffer).unwrap());
