im not sure exactly where or what lets u know that you need a reboot,
however your only really going to need to reboot on a server when there is a
new kernel installed and your better off scheduling the downtime
manually when you see a new kernel in the updates to minimise the impact
+ in the event that the new kernel doesnt boot,  resolve the issues.
rather than springing the reboot on you at any time and having the concequences
that follow.
