%description
Sysdig instruments your physical and virtual machines at the OS level
by installing into the Linux kernel and capturing system calls and
other OS events. Then, using sysdig's command line interface, you can
filter and decode these events in order to extract useful information.
Sysdig can be used to inspect systems live in real-time, or to
generate trace files that can be analyzed at a later stage.

%description -l pl.UTF-8
Sysdig obsługuje maszyny fizyczne i wirtualne na poziomie systemu
operacyjnego, instalując się w jądrze Linuksa i przechwytując
wywołania systemowe oraz inne zdarzenia systemu. Następnie, przy
użyciu interfejsu linii poleceń sysdiga można odfiltrować i zdekodować
te zdarzenia, aby wydobyć z nich przydatne informacje. Sysdiga można
używać do dozorowania systemów w czasie rzeczywistym albo generowania
plików śladów do późniejszej analizy.
