Instrumented 🎸
Observe your service.
You can specify the global metrics prefix with the METRICS_PREFIX
env var,
and provide default labels with the METRICS_LABELS
env var, which accepts a
command separated list of label=value
pairs. For example:
METRICS_PREFIX=myapp
METRICS_LABELS=app=myapp,env=prod,region=us
Example
extern crate instrumented;
extern crate log;
extern crate reqwest;
use instrumented::instrument;
#[instrument(INFO)]
fn my_func() {
use std::{thread, time};
let ten_millis = time::Duration::from_millis(10);
thread::sleep(ten_millis);
}
#[derive(Debug)]
pub struct MyError;
#[instrument(INFO)]
fn my_func_with_ok_result() -> Result<String, MyError> {
use std::{thread, time};
let ten_millis = time::Duration::from_millis(10);
thread::sleep(ten_millis);
Ok(String::from("hello world"))
}
#[instrument(INFO)]
fn my_func_with_err_result() -> Result<String, MyError> {
use std::{thread, time};
let ten_millis = time::Duration::from_millis(10);
thread::sleep(ten_millis);
Err(MyError)
}
fn main() {
let addr = "127.0.0.1:5000".to_string();
instrumented::init(&addr);
my_func();
assert_eq!(my_func_with_ok_result().is_ok(), true);
assert_eq!(my_func_with_err_result().is_err(), true);
let body = reqwest::get(&format!("http://{}/metrics", addr))
