The public_addr is stripped on the first semicolon.
Problem also exists on the `ceph_osd_metadata` metric for the `cluster_addr` label
ceph_osd_metadata{back_iface="bond-storage",ceph_daemon="osd.0",cluster_addr="[2001",device_class="ssd",front_iface="bond-mgmt",hostname="node1.example.net",objectstore="bluestore",public_addr="[2001",ceph_version="ceph version 15.2.4 (7447c15c6ff58d7fce91843b705a268a1917325c) octopus (stable)"} 1.0
ceph_osd_metadata{back_iface="bond-storage",ceph_daemon="osd.1",cluster_addr="[2001",device_class="ssd",front_iface="bond-mgmt",hostname="node1.example.net",objectstore="bluestore",public_addr="[2001",ceph_version="ceph version 15.2.4 (7447c15c6ff58d7fce91843b705a268a1917325c) octopus (stable)"} 1.0
ceph_osd_metadata{back_iface="bond-storage",ceph_daemon="osd.2",cluster_addr="[2001",device_class="ssd",front_iface="bond-mgmt",hostname="node1.example.net",objectstore="bluestore",public_addr="[2001",ceph_version="ceph version 15.2.4 (7447c15c6ff58d7fce91843b705a268a1917325c) octopus (stable)"} 1.0
Unfortunately I do not use the ganesha nfs/cephfs/rgw features of ceph but it would not surprise me if those metrics contained the same bug on an ipv6 cluster
