UIM - url_response device identification in USM/OC

By default, url_response identifies the URLs devices with the IP and Host Name resolved by the target url.

When url_response target URLs are behind a Load Balancer or behind a CDN (content delivery network), meaning that the IP and host name resolved by the target URL is different from the target hostname, it can give the possibility of mixed up and over correlated targets in USM. 

The scenario:

I have several different URLs that point to a Load Balancer or to a CDN that all return the same hostname and IP. With the default configuration all URL's are mixed up and correlated into 1 single device in USM.

•  Can url_response use the Host Name for device identification instead of the hostname and IP the URL is actually resolved into? 

•  Is it possible to use identify devices by their profile name rather than the IP address?

 useHostNameForDeviceIdentification = yes 

•  To enable the use of Profile for device identification add the following key to the probe:

useProfileNameForDeviceIdentification = yes

Important! If you specify the value of the useHostNameForDeviceIdentification key as Yes, the probe always uses the Device hostname to identify URLs in USM. 


Additional Information

If you didn't enable this option since the beginning of the deployment of the monitoring it might be necessary to, first, clean up the inventory by deleting the existing devices  and then redo the configuration of the url's from scratch.
