http status codes in http monitor

The bigd (LTM) HTTP monitor should already look at both the header and content:

SOL3618: BIG-IP HTTP health monitors match Receive String against payload and HTTP headers (including cookies)

Note that this is not the behaviour of the DNS (aka GTM) http monitor, which works quite differently (see SOL13622 for details on that)

I've just done a test, and it seems to match the HTTP response code correctly:

ltm monitor http http_200_ok {
    adaptive disabled
    defaults-from http
    destination *:*
    interval 5
    ip-dscp 0
    recv "200 OK"
    send "GET / HTTP/1.0\r\n\r\n"
    time-until-up 0
    timeout 16
}

... and it matched this response:

HTTP/1.1 200 OK
Date: Wed, 13 Jan 2016 00:27:48 GMT
Server: Apache/2.4.7 (Ubuntu)
Last-Modified: Tue, 01 Sep 2015 02:47:01 GMT
ETag: "a6d-51ea69081150d"
Accept-Ranges: bytes
Content-Length: 2669
Vary: Accept-Encoding
Connection: close
Content-Type: text/html

/var/log/bigdlog shows that it did match:

[0][20364] 2016-01-12 16:31:33.833476: ID 44    : Response Code: 200 (OK) [ addr=::ffff:5.0.0.11:80 srcaddr=::ffff:5.0.0.211%0:57568 ]
[0][20364] 2016-01-12 16:31:33.833486: ID 44    :(_recv_active_service_ping): Response matched regex [ addr=::ffff:5.0.0.11:80 srcaddr=::ffff:5.0.0.211%0:57568 ] send=GET / HTTP/1.0\x0d\x0a\x0d\x0a
 recv=200 OK

ah, i have found out why.

the missing "HTTP/1.0" in send string caused this situation
