To stop the platform daemon on a Linux Supervisor, type the following at the command line.

<user>@<host>:/usr/bin# niagaradctl stop
Stopping Niagara Daemon:                            [  OK  ]

To verify that the daemon has stopped, type the following at the command line.

<user>@<host>:/usr/bin# niagaradctl status
niagarad is stopped

Typically you rarely stop the platform daemon (and thus station) on any Supervisor, except immediately before installing a new point release, meaning an upgrade.
