You'll see, for example, that simple FTP transfer speed got affected by a VM that had a configured memory limit. You could have troubleshoot the network as much as you could, the problem just wasn't there….
First he presents which tools and on which level are best to use the performance problems. vCenter Operations is suggested as a good tool, since it uses every possible metrics available. You can go back one month and see, what changed between the time. Then esxtop, and so on..
A popular CPU ready through esxtop shows %ready and through vSphere client it shows in miliseconds. It takes the data from the esxtop.
Then virtual RAM and the memory management gets in discussion, with Transparent page sharing (TPS), Ballooning, compression and swapping. Some good practices there as well..
