2.11. SystemTap

SystemTap is a tracing and probing tool that lets you monitor and analyze operating system activities, especially kernel activities, in fine detail. It provides information similar to the output of tools like top, ps, netstat, and iostat, but includes additional options for filtering and analyzing collected data.
SystemTap provides a deeper, more precise analysis of system activities and application behavior to allow you to pinpoint system and application bottlenecks.
