+From support:
+That information is logged via syslog for the opposite controller. For example, to find the information I did here, I looked in the syslog output on the controller that was passive at the time these alerts occurred.
+You can look that information up yourself by opening an SSH session to the passive controller, navigating to the /root/syslog directory and examining the files. The "controller_{a,b}" file shows the output for today. Extract the controller_a.0.bz2 file and read the output of the resulting controller_a.0 file to see the output for yesterday. controller_a.1 would contain the output for the day before yesterday, and so on.
