Package taskstats provides access to Linux's taskstats interface, for sending
per-task, per-process, and cgroup statistics from the kernel to userspace. MIT

When instrumenting Go programs, use either the
taskstats.Self()ortaskstats.TGID()method. Using thePID()method on multithreaded programs, including Go programs, will produce inaccurate results. -
Access to taskstats requires that the application have at least
CAP_NET_RAWcapability (see capabilities(7)). Otherwise, the application must be run as root. -
If running the application in a container (e.g. via Docker), it cannot be run in a network namespace -- usually this means that host networking must be used.
