Apparently it is an undocumented feature that, when you click on the "Graphs" menu entry, it installs Netdata. No notification, no warning, no confirmation prompt, it just installs Netdata. And runs in, which means:
- it will now have another service adding to the load of your system
- it will spam you with e-mails every time your server does a daily backup
- it will add a public web interface to display all the server's stats and graphs, with no authentication, and showing all the configuration of your server including mount points and account usernames
Also it is now no longer possible to get rid of it. Sure, you can run the uninstaller, but then somehow CWP remembers that it's supposed to have it running, so every night when it checks for updated packages it will re-install Netdata for you.
Very comforting to know that you're in control of your server, and the software you use is properly documented and doesn't do stuff you're not aware of.
See my thread on the same topic which also is receiving "solutions" which ask ME to fix crap which shouldn't be there in the first place.
