Sysdig - Linux System Troubleshooting Tool
Sysdig is open source, Linux System Troubleshooting Tool: capture system
state and activity from a running Linux instance, then save, filter and
analyze. Think of it as strace + tcpdump + lsof + awesome sauce. With a
little Lua cherry on top.
Sysdig was born from a team’s constant frustration. System level
troubleshooting is just way more of a pain than it should be —
especially in distributed, virtualized, and cloud-based environments. So
they took the lessons they learned while building network monitoring
tools like WinPCap and Wireshark and created a new kind of system
troubleshooting tool for Linux.
Sysdig captures system calls and other system level events using a
linux kernel facility called tracepoints, which means much less overhead
than strace.
It then “packetizes” this information, so that you can save it into
trace files and filter it, a bit like you would do with tcpdump. This
makes it very flexible to explore what processes are doing.
Sysdig is also packed with a set of scripts that make it easier to extract useful information and do troubleshooting.
