how to store radosgw operations logging data to other storage backend?

[zhu_qiang_ws@xxxxxxxxxxx (zhu qiang)]

Hi all,
    how to store radosgw operations logging data to other storage backend?
    From ceph docs link : http://ceph.com/docs/master/radosgw/config/#configuring-operations-logging
      rgw ops log rados = false
      rgw enable ops log = true
      rgw ops log socket path = <path to socket>
  
Did anybody has done this practice?  and what backend is available to store the huge logs ?
Is logstash + redis a good choice ?

Thanks
