hyperlane-plugin-logger

Writes the log of a server to the console, to a file, or to both, and can log every request that the server answers.

LoggerPlugin::init(LoggerConfig {
    level: LevelFilter::Info,
    file: Some("server.log".to_owned()),
})?;

The request log is a middleware pair, so it is installed with the server. It does nothing until the logger is configured, so a service that never calls init writes no request log.

Configuration

The request log

Each answered request is written with its method, its path, its status and the time it took. The time is measured by a request middleware that notes when the request arrived, and read by a response middleware that writes the line.

Order

The request middleware uses the order -120, so it notes the arrival before the middlewares of the application run, and the response middleware uses the order 100, so it reports the answer after the application built and sent it. The plugins that answer a request keep the negative orders, and an application that gives its own middlewares positive orders runs between the two.
