Rust

note

If you need an example application to test this integration, please refer to our Rust OpenTelemetry repository.

This guide explains how to configure your Rust application to send logs to Logz.io via OpenTelemetry.

Prerequisites​

  • A Rust application with logging capabilities.
  • An active Logz.io account
  • Your log shipping token
  • Port 8071 available on your host system

Add Dependencies​

To send logs to Logz.io via OpenTelemetry, add the required dependencies to your Cargo.toml file:

[dependencies]
log = "0.4"
opentelemetry = "0.27"
opentelemetry-appender-log = "0.27"
opentelemetry_sdk = { version = "*", features = ["rt-tokio"] }
opentelemetry-otlp = { version = "*", features = ["http-proto", "reqwest-client", "reqwest-rustls"] }
tokio = { version = "1", features = ["full"] }

Configure Logging and Implement OTLP Communication​

Import the following modules into your existing app:

use opentelemetry_appender_log::OpenTelemetryLogBridge;
use opentelemetry_otlp::{WithExportConfig, WithHttpConfig};
use std::collections::HashMap;

Add the exporters and logger provider section to your code:

async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync + 'static>> {

    let endpoint = "https://otlp-listener.logz.io/v1/logs";
    let api_token = "LOGZ_IO_TOKEN";

    let logger_provider = opentelemetry_sdk::logs::LoggerProvider::builder()
        .with_batch_exporter(
            opentelemetry_otlp::LogExporter::builder()
                .with_http()
                .with_endpoint(endpoint)
                .with_headers(HashMap::from([
                    ("Authorization".to_string(), format!("Bearer {}", api_token), ),
                    ("User-Agent".to_string(), format!("logzio-rust-logs-otlp"), ),
                ]))
                .build()?,
            opentelemetry_sdk::runtime::Tokio,
        )
        .build();
    
    let log_bridge = OpenTelemetryLogBridge::new(&logger_provider);

Replace LOGZ_IO_TOKEN with the shipping token of the account.

If needed, update the https://otlp-listener.logz.io/v1/logs with the URL of your hosting region.

Run the application and check Logz.io for logs​

Run your application with cargo run. Give your logs some time to get from your system to ours.
