настроить мониторинг производительности (set up performance monitoring)
Примечание (Note)
The official way of knowing if perf_event_open() support is
enabled is checking for the existence of the file
/proc/sys/kernel/perf_event_paranoid.
CAP_PERFMON capability (since Linux 5.8) provides secure approach
to performance monitoring and observability operations in a
system according to the principal of least privilege (POSIX IEEE
1003.1e). Accessing system performance monitoring and
observability operations using CAP_PERFMON rather than the much
more powerful CAP_SYS_ADMIN excludes chances to misuse
credentials and makes operations more secure. CAP_SYS_ADMIN
usage for secure system performance monitoring and observability
is discouraged in favor of the CAP_PERFMON capability.
