tracing-gelf
A Graylog tracing
library.
Usage
Add this to your Cargo.toml
:
[dependencies]
tracing-gelf = "0.6"
The current tracing-gelf
requires Rust 1.53 or later.
TCP Logging
use tracing_gelf::Logger;
#[tokio::main]
async fn main() {
// Graylog address
let address = "127.0.0.1:12201";
// Initialize subscriber
let conn_handle = Logger::builder().init_tcp(address).unwrap();
// Spawn background task
// Any futures executor can be used
tokio::spawn(conn_handle.connect());
// 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(|| {
let test = tracing::info_span!("deeper in cave", smell = "damp");
test.in_scope(|| {
// Send a log to Graylog, inside a nested span
tracing::warn!(message = "oh god, it's dark in here");
})
});
// Send a log to Graylog
tracing::error!(message = "i'm glad to be out", spook_lvl = 3, ruck_sack = ?["glasses", "inhaler", "large bat"]);
}
UDP Logging
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);
}
