Subject: mgr/mirroring: Display remote fsid and mon_host in daemon status
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=c1262399d0758823639b97c4ca93bdd045b72865;p=ceph-ci.git

mgr/mirroring: Display remote fsid and mon_host in daemon status

The cephfs_mirror daemon returns the basic remote info.
Fetch the remote fsid and mon_host from the monitor
config map and append it.

Sample output:
[

    "daemon_id": 4153,
    "filesystems": [
      {
        "filesystem_id": 1,
        "name": "a",
        "directory_count": 0,
        "peers": [
          {
            "uuid": "29304477-1fd7-4709-b9f7-8153acebbafd",

              "fsid": "5682c8e5-50cd-4cfd-b75c-5354dcdda487"
            },
            "stats": {
              "failure_count": 0,
              "recovery_count": 0
            }
          }
        ]
      }
    ]
  }
]
