While CPU Usage (Precise) is great for seeing how much CPU time a process is using, and why it is sitting idle, the CPU Usage (Sampled) table is the right tool for figuring out where CPU time is being spent. Remember that these are calls to the operating system – kernel calls. That is an average read of 68 bytes each time.

This means that Dynatrace continues full operation when a majority of nodes are up and a maximum of two nodes are down at a time. The network latency between cluster nodes should be around 10 ms or less. Cluster nodes reside in both data centers and they continuously process, store, and replicate data. What’s next?

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. Its goal is to assign running processes to time slices of the CPU in a “fair” way. So why mess with it?
