slog-mongodb
MongoDB extension for Rust’s logging library slog-rs. Serializes slog messages to BSON documents and stores them in a MongoDB collection. To reduce the stress on the database, the logged messages are buffered and only sent in configurable time intervals.
slog_mongodb
MongoDB extension for Rust’s logging library slog-rs. Serializes slog messages to BSON documents and stores them in a MongoDB collection. To reduce the stress on the database, the logged messages are buffered and only sent in configurable time intervals.
Usage
use slog::*;
fn main() {
let client = mongodb::Client::with_uri_str("mongodb://localhost:27017/").unwrap();
let db = client.database("some_db");
let logs = db.collection("logs");
let drain = slog_mongodb::MongoDBDrain::new(logs, std::time::Duration::from_secs(5)).fuse();
let drain = slog_async::Async::new(drain).build().fuse();
let log = Logger::root(drain, o!());
info!(log, "Hello MongoDB!");
}
Notes
By default, the logged messages contain the following values:
- “ts”: RFC3339 timestamp
- “level”: “TRCE”, “INFO”, “WARN”, “ERRO” or “CRIT”
- “leveli”: 4 - 0
- “msg”: the log message
This behavior can be changed by constructing the drain as follows:
use slog::*;
fn main() {
let client = mongodb::Client::with_uri_str("mongodb://localhost:27017/").unwrap();
let db = client.database("some_db");
let logs = db.collection("logs");
let drain = MongoDBDrainBuilder::new(logs, std::time::Duration::from_secs(5))
.add_key_value(o!("key" => "value")).build();
let drain = slog_async::Async::new(drain).build().fuse();
let log = Logger::root(drain, o!());
info!(log, "Hello MongoDB!");
}
Credits
The serde serialization as well as the overall design is copied from slog-json.
