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?

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.

Linux load averages are "system load averages" that show the running thread (task) demand on the system as an average number of running plus waiting threads. This measures demand, which can be greater than what the system is currently processing. Nowadays, the source code to old operating systems can also be found online.
