    You can post monitor related questions in the new forum:

    In general, you can configure an HTTP 1.1 formatted send string for a monitor that includes the domain of the server in the Host header:

     

     

    send string:

     

     

    GET /index.html HTTP/1.1\r\nHost: www.abc1.com\r\nConnection: close\r\n

     

     

    receive string:

     

     

    200 OK

     

     

    See SOL1096 (Click here) for details. Note that in 9.x, I think the final \r\n sequence is added automatically so you don't need to add two carriage return/line feeds.

  • Hi, I configured as following:

     

     

    http_monitotor1

     

     

    send string:

     

     

    GET /index.html HTTP/1.1\r\nHost: www.abc1.com\r\nConnection: close\r\n

     

     

    receive string:

     

     

    200 OK

     

     

    and http_monitotor2

     

    end string:

     

     

    GET /index.html HTTP/1.1\r\nHost: www.abc2.com\r\nConnection: close\r\n

     

     

    receive string:

     

     

    200 OK

     

     

    and assigned it to pool, it is Ok-> it let me know members pool worked well

     

    But I wonder that how can I recognize on BIG-IP LTM one Website down or not? Can I recognize it on BIG-IP ? thanks for your help.

    You can configure one pool per web application and then only use the web app-specific monitor for that pool. If the monitor fails, the node in only that pool gets marked down. It doesn't matter whether the pool member is defined in multiple pools.
