Sysdig - dig deeper - LinuxLinks
Sysdig is a universal system visibility tool with native support for containers.
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. Sysdig also makes it possible to create trace files for system activity, similarly to what you can do for networks with tools like tcpdump and Wireshark. This way, problems can be analyzed at a later time, without losing important information. Rich system state is stored in the trace files, so that the captured activity can be put into full context.
Think about sysdig as strace + tcpdump + htop + iftop + lsof + …awesome sauce.
