Firstly, start by installing the Dynatrace OneAgent on the hosts where you’ll be running your application test. If you have a distributed environment with multiple servers hosting your webservers, app servers, and database, I suggest you install the OneAgent on all these servers to get full end-to-end visibility.

Plotting the percent performance loss vs syscall rate per CPU, for my microbenchmark: Applications that have high syscall rates include proxies, databases, and others that do lots of tiny I/O. Also microbenchmarks, which often stress-test the system, will suffer the largest losses. Linux 4.14.12-virtual 05:24:52 PM 0.00
