How to change hostnames shown in Nagios LS GUI --> Admin/Instance Status.
I'm after hardware upgrade and I replaced all nodes for new ones (new server, ip, name). Migration was nice and easy, all works, but the names of nodes

On very 1st installation of Nagios LS, setup process found proper names and IPs for all nodes.
But all new Nagios LS sewers shows as 'localhost' (IP is shown in proper way in Admin/Instance Status).
From cli, all is messed up, all hosts are 'localhost' with 127.0.0.1 IP
From OS (RHEL8) point of view, hostname is OK on each node (/etc/hostname, hostnamectl, /etc/hosts, nmtui - shows correct data)
During upgrade Nagios LS was in version 2.1.13 , now it's 2.1.15 (upgrade didn't help)
Code: Select all
curl -XGET 'http://localhost:9200/_cat/nodes?v'
host ip heap.percent ram.percent load node.role master name
localhost 127.0.0.1 6 61 0.00 d m xxxxxxxxxxxxxxxxxxxxxxxxxxxx9
localhost 127.0.0.1 4 61 0.01 d m xxxxxxxxxxxxxxxxxxxxxxxxxxxx0
localhost 127.0.0.1 6 61 0.14 d m xxxxxxxxxxxxxxxxxxxxxxxxxxxxc
localhost 127.0.0.1 7 61 0.02 d * xxxxxxxxxxxxxxxxxxxxxxxxxxxx1
I hope I miss some little step while configuration, but can't find it…
