Hi,
I have created health monitor on next-hop router as HTTP monitor since the connected router is blocking ICMP protocol.
What I have done here:
1.Create monitor type as HTTP with Send String (...

NimbostratusAgree with Michael J regarding the end device's HTTP server status and using curl to test. My humble addition:
Based on your receive string your expecting HTTP 1.1. HTTP 1.1 requires the 'HOST' header in the send string. It is fine if the header is blank, but it must be there. Example send string:
GET / HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n
You can also review the health monitor traffic using 'tcpdump' which can quickly show if the server is rejecting your Send String - server will usually send back a 'Bad Request' response if it doesn't like the syntax.
