Is there a way to add Bro server hostname field into all the Bro log types? We have 5 Bro servers capturing traffic on different network nodes, we are trying to add each server/sensor hostname into all the log types so analyst can identify where the logs are coming from.


We added a log extension mecahnism a while ago. Here's a snippet you could start from...

option my_server_name = "";
type MyLogExtension: record {
        server_name:   string &log;
function add_my_log_extension(path: string): MyLogExtension
        return MyLogExtension($server_name = my_server_name);
redef Log::default_ext_func = add_my_log_extension;
