Referencing an external file

Elastic Stack Logstash
1

HI,

I have a scenario where I want to match a log entry with multiple IP addresses and website names.

I want to check if any of these IPs and addresses are in the forbidden list, To do that i think i need to check if the IP/Url is in a list of forbidden url/ips in an external file.

Is it possible in logstash.

Regards,
Debarun.

Have a look at the translate filter.
