tracing-logstash
The absolute minimum amount of code I could get away with for writing tracing messages/logs in the https://github.com/logstash/logstash-logback-encoder#standard-fields format.
Currently built for use in a single application with a single log consumer.
Installation
You can include this library in your Cargo.toml file:
[dependencies]
tracing-logstash = "0.6.1"
Usage
fn main() {
let logger = tracing_logstash::Layer::default()
.event_format(tracing_logstash::logstash::LogstashFormat::default()
.with_constants(vec![
("service.name", "tracing-logstash".to_owned()),
])
);
let env_filter = EnvFilter::try_from_default_env()
.or_else(|_| EnvFilter::try_new("info"))
.unwrap();
let collector = Registry::default().with(logger).with(env_filter);
tracing::subscriber::set_global_default(collector).unwrap();
tracing::info!("Hello, world!");
}
