+| ceph_rgw_req| Number total of requests for the daemon (GET+PUT+DELETE)   Useful to detect bottlenecks and optimize load distribution.|
+| ceph_rgw_qlen| RGW operations queue length for the daemon.|
+|     Useful to detect bottlenecks and optimize load distribution.|
+| ceph_rgw_failed_req| Aborted requests.|
