Timer jobs explained#
Ubuntu Pro Client (
pro) sets up a
systemd timer to run jobs that need to be
carried out periodically. Every time the timer runs, it decides which jobs need
to be performed based on their intervals. When a job runs successfully, its next
run is determined by the interval defined for that job.
The jobs that
pro runs periodically are
update_messaging updates the MOTD and APT messages every 6 hours. It ensures
that the MOTD and APT messages displayed on the system match those that are
available/enabled. It finds updated information about available packages or
security updates and shows these to the user.
metering pings the Canonical servers for contract metering every 4 hours. It
informs Canonical which services are enabled on the machine.
metering job only runs when attached to an Ubuntu Pro subscription.
