You can simply query /

This is what I use in Varnish to do a health check:

backend rgw {
    .host               = "127.0.0.1";
    .port               = "7480";
    .connect_timeout    = 1s;
    .probe = {
        .timeout   = 30s;
        .interval  = 3s;
        .window    = 10;
        .threshold = 3;
        .request =
            "GET / HTTP/1.1"
            "Host: localhost"
            "User-Agent: Varnish-health-check"
            "Connection: close";
    }
}

Works fine, RGW will respond with a 200 OK in /
