Server Statistics

The MuStats class can give you various statistics about your server.

public class StatisticsExample {
    public static void main(String[] args) {
        MuServer server = httpServer()
            .addHandler((req, resp) -> {
                MuStats stats = req.server().stats();
                long completedRequests = stats.completedRequests();
                long bytesRead = stats.bytesRead();
                long bytesSent = stats.bytesSent();
                resp.write("There have been " + completedRequests + " requests with " + bytesRead
                    + " uploaded and " + bytesSent + " downloaded.");
                return true;
            })
            .start();
        System.out.println("Server started at " + server.uri().resolve("/handle-it"));
    }
}

Here are some stats for this website:

Connection info

You can access all the existing connections to your server by calling server.activeConnections() which returns a set of HttpConnection objects. This allows you to see which HTTP protocols are in use, which TLS versions are used, the ciphers used, etc. This can be useful when analysing which TLS settings will not impact your users.

The MuRequest object also gives you access to the current connection via the connection() method. For example, you are accessing this web page over HTTP/2 using TLSv1.3 with the TLS_AES_256_GCM_SHA384 cipher. This connection, started at 2024-12-21T15:09:57.631322497Z has served 0 requests.
