I wrote simply these codes;
let whois_lookup = whois_lookup_ip(to_string($message.IP), “src_addr”);
I tested some IP on whois lookup tables page, that is work. On search page i have IP and src_addr fields, but in debug line i get this output:
2018-11-06T14:24:51.110+03:00 INFO [Function] PIPELINE DEBUG: Passed value is NULL.
so, this does not work for me.
Have you any idea about this?
