I'm using varnishncsa to log requests that are taking to long to be answered on my backend servers using the following command:

varnishncsa -F '%t "%r" %s %T' | awk '$7 > 10 {print}'

I was trying to add information on the backend name but this is not being displayed on varnishncsa output:

sub vcl_backend_response {
    std.log("backend_name:" + beresp.backend.name);
}

what I'm doing wrong?
