How to log the IP address client from an LTM policy?


I created an LTM policy which tries to log the IP address of the client according to this guide but it does not run because the text logged in /var/log/ltm is:

Refused connection to [HTTP::uri] from [IP::client_addr]

and also

Refused connection to tcl:[HTTP::uri] from tcl:[IP::client_addr]


The F5 BIG IP version is


Best regards
