gelf_logger
The Graylog Extended Log Format (GELF) is a log format that avoids the shortcomings of classic
log formats. GELF is a great choice for logging from within applications. There are libraries
and appenders for many programming languages and logging frameworks so it is easy to implement.
You could use GELF to send every exception as a log message to your Graylog cluster.
The logger will:
- serialize log entries using the serde_gelf crate.
- bufferize the result into memory.
- batch send over network using TCP/TLS.
Example
use std::time::Duration;
use gelf_logger::{gelf_warn, Config, GelfLevel};
use log::info;
use serde_derive::Serialize;
#[derive(Serialize)]
struct Myapp {
name: String,
version: String,
}
impl Default for Myapp {
fn default() -> Myapp {
Myapp {
name: env!("CARGO_PKG_NAME").into(),
version: env!("CARGO_PKG_VERSION").into(),
}
}
}
fn main() {
let cfg = Config::builder()
.set_hostname("localhost".into())
.set_port(12202)
.set_level(GelfLevel::Informational)
.set_buffer_duration(Duration::from_millis(300))
.set_buffer_size(500)
.put_additional_field("myValue".into(), gelf_logger::Value::I64(10))
.set_null_character(true)
.build();
gelf_logger::init(cfg).unwrap();
info!("common message");
gelf_warn!(extra: &Myapp::default(), "My app info");
gelf_logger::flush().unwrap();
}
