How do I access the logs to find out the root cause of a controller that went offline?

I have a pair of redundant local controllers.  One controller went offline for some reason and came back online after a physical reboot was initiated by local IT staff.  I am trying to find the root cause from the controller perspective.  Did it lose power?  Was the network connection broken? etc.  Regardless, the controller did not recover and needed a physical reboot. 

 

My question is, how do I access the logs that will indicate the health and history of the controller?

 

Any input would be appreciated.

 

Thanks

if you rebooted manually, it will say "user pushed reset" as the cause.  I would type "tar crash" and and see if there are any crash files that you can send to support.
