tracing-aliyun-sls

Enable tracing integration with Aliyun SLS, also support log crate.

Feature Flags

• lz4: enable lz4 compression for logs.
• deflate: enable deflate compression for logs.
• log-comp: enable the Logger for log crate.
• derive-key: enable the ability to derive the shard key (128 bits hex) from any string using BLAKE3.
• rustls: By default, it enables reqwest/default-tls, if you want to use rustls as the TLS backend, enable this feature also disable default features.

Note: lz4 and deflate cannot be enabled at the same time.

Example

To use with tracing:

use tracing_aliyun_sls::SlsLayer;
use tracing_subscriber::layer::SubscriberExt;
use tracing_subscriber::util::SubscriberInitExt;

#[tokio::main]
async fn main() {
   let (layer, _guard) = SlsLayer::builder()
        .access_key("access_key")
        .access_secret("access_secret")
        .endpoint("cn-hangzhou.log.aliyuncs.com")
        .project("project")
        .logstore("logstore")
        .shard_key("shard_key") // Optional if you want to use `KeyHash` mode
        .max_level(tracing::Level::INFO) // Optional, default is `tracing::Level::TRACE`
        .drain_timeout(std::time::Duration::from_secs(10)) // Optional, default is 5 seconds
        .build_layer();
    
    tracing_subscriber::registry()
        .with(layer)
        .init();
}

If you want to use it with log, enable the log-comp feature:

use tracing_aliyun_sls::SlsLayer;
use tracing_subscriber::layer::SubscriberExt;
use tracing_subscriber::util::SubscriberInitExt;

#[tokio::main(flavor = "current_thread")]
async fn main() {
   SlsLayer::builder()
        .access_key("access_key")
        .access_secret("access_secret")
        .endpoint("cn-hangzhou.log.aliyuncs.com")
        .project("project")
        .logstore("logstore")
        .shard_key("shard_key") // Optional if you want to use `KeyHash` mode
        .max_level(tracing::Level::INFO) // Optional, default is `tracing::Level::TRACE`
        .drain_timeout(std::time::Duration::from_secs(10)) // Optional, default is 5 seconds
        .build_logger()
        .init();
}
