status code http monitor

A monitor can look for different status codes to base its up/down decision, so you could configure an HTTP monitor to mark nodes up if the response is a 200 and down if not. But it isn't going to report back to you, other than node up/down status what the server returned. You could use an external monitor with cURL and have that response logged, but again if you're just troubleshooting a monitor, your best bet is still tcpdump.
