I read in the documentation:
The built-in Netdata UI, accessible from the Netdata button on the Reporting screen in TrueNAS 24.04 and 24.10, is removed in TrueNAS 25.04 (and later) for security hardening. Users wishing to continue using the Netdata UI to monitor system reports can install the Netdata application.
so I’m quite surprised to see a netdata.service consuming CPUs.
AFAICT, it still serves the Reporting section of the UI, since it stops when the the netdata.service is stopped.
Fair enough, but then why ask users to install a Netdata app on top of the existing one to get the full Netdata reporting ?
