http://nginx.org/en/docs/http/ngx_http_map_module.html

http {

    map $status $normal {
        ~^2  1;
        default 0;
    }
    map $status $abnormal {
        ~^2  0;
        default 1;
    }
    map $remote_addr $islocal {
        ~^127  1;
        default 0;
    }

    server {

        access_log logs/access.log combined if=$normal;
        access_log logs/access_abnormal.log combined if=$abnormal;
        access_log logs/access_local.log combined if=$islocal;

    }  
}
