we are deploying several test nodes on non critical machines : webservers on almalinux
(yes live webservers are basic non contrical toys or a sandboxes)
moving machines are critical
some nodes are connected with random data from the node pushed to the dashboards.
one node is marked as unseen.
there is nothing about this in documentation.
some hint about that should be reviewed ?

An unseen node is a node that was claimed to Cloud, but its Agent never managed to successfully establish a connection. The primary way to start debugging this is having a look at the Agent’s logs and find the log entries that mention ACLK. If you are running a recent nightly you can extract the related lines with the following:
$ sudo journalctl --namespace=netdata -S "24 h ago" THREAD_TAG=ACLK_MAIN
If you are using an older version of the Agent, you can instead find lines matching ACLK in /var/log/netdata/error.log or /var/log/netdata/daemon.log, depending on the version.
If you can provide the node’s ID, as recorded in /var/lib/netdata/cloud.d/claimed_id, I can also look it up in our Cloud side logs.
