From my experience, going from one to multiple monitoring nodes gets way more complicated than expected; make sure you have your timestamps across the nodes right, especially when you decide to go down with the interval to 1 minute or less.
Also, investing time in a testing setup where all scenarios can be tested paid off greatly. Having scripts covering all edge cases lets you sleep better when you have paying customers :-)
Thanks, and am in full agreement with both the difficulty of multi-node sync and testing. I have test coverage of most of the front-end, but I need to do more with the backend to make sure what is working great now works great a year from now.
