Chapter 11: Monitoring Servers

Chapter 11 dealt with, shock of shocks, monitoring servers. (Gee, bet you weren't expecting that from the title!) In any case, the lab had me mostly in the reliability and performance utrility, building different graphs and data collectors. The most important takeaway from this lesson was, at least to me:  Be careful what you put on the same graph. Things that are percentage based will only have a value of 0-100 (Sadly for the Spinal Taps of the computing world, the hardware in a PC, even a server, does not go to 11.) whereas other things will be measured in units that can go WAY past 100. However, even if you do put things with different ceilings together on the same graph, you'll still at least be able to see where the spikes are.
