KernelCare is often deployed on a large number of servers. Adding those servers one by one is a hassle. In that case, KernelCare key can be used to deploy and register multiple servers at once.
Registration is still straightforward:
kcarectl --register [YOUR KEY]
The key can be obtained from CLN (see image).
The same key can be used for all the servers.
Alternatively, you can partition servers in groups (a group per key). Such partitioning is convenient for monitoring - as you can monitor each group separately using Zabbix or Nagios.
