health monitor send string not working on new version 11

Hello All,

 

We just currently upgraded to the new 11 version appliance. Some how the health monitor is NOT working properly on the pool with 2 members.

 

GET /global_servername.txt\r\n HTTP/1.1\r\n Host: support.qad.com\r\n Connection: Close\r\n

 

This health monitor "send string" keeps flagging both the 2 members down.

 

Has the syntax changed and if so, can anyone assist?

 

 

Regards,

 

TRX

    Hi trx

     

     

    You don't say what version you're upgrading from but there have been changes to the HTTP monitor strings over the last few versions, specifically around the CR and LF.

     

     

    See the following two articles for more info - hopefully this should help you out:

    Hope this helps

    Thanks! I was missing another "\r\n" at the end of the send string section.
