"num_caps": 655,
"state": "open",
"replay_requests": 0,
"completed_requests": 1,
"reconnecting": false,
"inst": "client.9762766 10.9.1.2:0\/4202511977",
"client_metadata": {

"ceph_version": "ceph version 0.94.10 (b1e0532418e4631af01acbc0cedd426f1905f4af)",
"entity_id": "log_cephfs",
"hostname": "ac_xxx-client00.gz01",
"mount_point": "\/mnt\/log"
}
}
]

$ ceph daemon mds.0 session ls | grep "hostname\|inst"
"inst": "client.9762766 10.9.1.2:0\/4202511977",
