Anuj_Chaudhary_if i am configuring and assigning pool to the above monitor.. Pool are becoming down..- Anuj_Chaudhary_what should i used in send string ? I used below string : GET /myitprodHealthCheck/HealthCheck\r\n is this correct ?

- How does the /arsys directory in the Send String specs fit into the URI you want to check? Have you checked log messages? You can also use curl on the BIG-IP system command line to check the monitor send string yourself and see what HTTP response you are actually getting. For example, curl :8080/myitprodHealthCheck/HealthCheck
- Don't know why I didn't notice this before, by try adding another "/" at the end of the Send String. In other words GET /myitprodHealthCheck/HealthCheck/\r\n
Please forgive me if I interpreted your question incorrectly though the solution article below should provide all of the details regarding the development of application health monitors.

Example: GET /index.html HTTP/1.1\r\nHost: host.domain.com\r\nConnection: Close\r\n\r\n
- Anuj_Chaudhary_GET /healthcheck.html HTTP/1.1\r\nHost: smp.interglobe.com\r\nConnection: Close\r\n\r\n I used above monitor, but its making pool member down. however if I am using gateway ICMP monitor ,pool members are coming up..
- If this is a production application, please do not use the ICMP monitor as it will only tell you if the server itself is responding to ICMP but nothing about the application itself. Try this and if it does not work, I recommend using a tool such as fiddler to view HTTP requests and responses. Then to take it a step further, I would add an expected receive string such as HTTP/1.1 200 OK or something in the web server response. I am running a web server pool using this health monitor so I am hoping it works for your environment as well. Let me know either way. GET / HTTP/1.1\r\nHost: smp.interglobe.com\r\nConnection: Close\r\n\r\n
- Anuj_Chaudhary_i added receive string also as HTTP/1.1 200 OK and used above monitor as recommended by you,but still its marking pool down. Now I will use fiddler and lets c the response.
