Using sysdig to Troubleshoot like a boss

If you haven't seen it yet there is a new troubleshooting tool out called sysdig. It's been touted as strace meets tcpdump and well, it seems like it is living up to the hype. I would actually rather compare sysdig to SystemTap meets tcpdump, as it has the command line syntax of tcpdump but the power of SystemTap. In this article I am going to cover some basic and cool examples for sysdig, for a more complete list you can look over the sysdig wiki.

Advanced Linux System Statistics and Diagnostics with SystemTap

In one of the first posts of this blog I covered some basic SystemTap functionality from an email that I sent to members of my team, but I have always felt that I haven't given SystemTap as thorough of an article as this incredible tool deserves. Today I want to correct that. For today's article I will show how to compile SystemTap scripts on one server while running the compiled module on a production server without installing debug-info or devel packages in production.
