One lesson I took from the situation (when I faced it) was to monitor your monitors constantly.  Like, a daily summation (of all monitors)script that arrives at like 1pm, or whenever you just get out of bed and begin to work (;)), that is, at some predictable time because, if it doesn't arrive, you have issues.

Another was, whenever updating a system, treat it like a port from one environment to another - meaning - if you can, run the monitor in an unchanging environment before and after changing the other and then compare the results.

A way to interpret that - if you are about to upgrade package A on system B, first port your code to new environment C and make sure what's on C agrees with what's on B.  Then change A and see if C still agrees with B.

Today, the young kids keep changing the layers and layers of code and you can't predict where a change will alter what a monitor sees.
 
Why can't people just stop updating software...sigh.
