Hello, I have a question regarding nginx integration - access-log. I set it up and everything is working but I want to change source.ip to hostname. I'm using Fleet with agent and nginx integration. I added to Collect logs from Nginx instances - Nginx access logs - Advanced options - Processors: - add\_fields: target: dns fields: ip: '104.26.6.148' - dns: type: reverse fields: dns.ip: resolved.ip nameservers: ['169.254.169.253'] tag\_on\_failure: [\_dns\_reverse\_lookup\_failed] it is working with static IP, but how can I resolve source.ip comming from logs ? I found fields which are holding IP address. I want to resolve , but what I read those fields are not set/accessible in processors: related.ip source.address source.ip nginx.access.remote\_ip\_list Is there some way how can I resolve hostname and set it to new or existing field ? thanks Peter ---
