tracing-gelf

A Graylog tracing library.

Usage

Add this to your Cargo.toml:

toml [dependencies] tracing-gelf = "0.6"

TCP Logging

```rust use tracing_gelf::Logger;

[tokio::main]

async fn main() { // Graylog address let address = "127.0.0.1:12201";

// Start tracing
let bg_task = Logger::builder().init_tcp(address).unwrap();

// Spawn background task
// Any futures executor can be used
tokio::spawn(bg_task);

// Send a log to Graylog
tracing::info!(message = "oooh, what's in here?");

// Create a span
let span = tracing::info_span!("cave");
span.in_scope(|| {
    // Log inside a span
    let test = tracing::info_span!("deeper in cave", smell = "damp");
    test.in_scope(|| {
        tracing::warn!(message = "oh god, it's dark in here");
    })
});

// Log a structured log
tracing::error!(message = "i'm glad to be out", spook_lvl = 3, ruck_sack = ?["glasses", "inhaler", "large bat"]);

}

```

UDP Logging

```rust use tracing_gelf::Logger;

[tokio::main]

async fn main() { // Graylog address let address = "127.0.0.1:12202";

// Start tracing
let bg_task = Logger::builder().init_udp(address).unwrap();

// Spawn background task
// Any futures executor can be used
tokio::spawn(bg_task);

// Send a log to Graylog
tracing::info!(message = "our dreams feel real while we're in them");

// Create a span
let span = tracing::info_span!("level 1");
span.in_scope(|| {
    // Log inside a span
    tracing::warn!(message = "we need to go deeper", music = "hans zimmer");

    // Create an nested span
    let inner_span = tracing::info_span!("level 5");
    inner_span.in_scope(|| {
        // Log inside nested span
        tracing::error!(message = "you killed me");
    });
});

// Log a structured log
tracing::info!(message = "he's out", spinning_top = true);

}

```
