Sep 13, 2011How to make an EAV to check a string deeper than 5,120 bytes into an HTTP response?
I need to make a monitor that searches for a word in a http response, but that word is in the end of the string.
Regular monitors goes only to 5,120 bytes, so i need to create an EAV (External Application Verification) for this task.
How do i do this?
Thanks.

Hi Thales,
As far as I'm aware, the 5120 byte limit is not user-configurable. You could use an external monitor instead:

Another thing to consider is writing a separate script that lives on your origin web servers that is a wrapper for a number of tests performed on the application. I've done this in the past so that the BIG-IP health monitor can be as simple as possible while leaving the logic in a script on the webservers. You can also build some caching into the test script as well to prevent overloading your backend with excessive requests from health monitors.

Thanks for the help.
For now i´ll try the EAV monitor. I´m not so familiar with server scripts.
In this example (http://devcentral.f5.com/wiki/AdvDesignConfig.HTTPMonitor_cURL_BasicGET.ashx), if i put my request at the URI and the string i expect at the RECV, will it work without the 5,120 bytes limit?
Thanks.
