I found reading these comments very interesting. From one point of view, I'm thinking "why did coreos need to be so aggressive?", and "boy, what a gift Solomon Hykes did to coreos by mismanaging this thing so badly"

It's interesting how most of the comments focus on the technical aspects of what the guy built. What I found interesting and inspiring is the time and passion that he puts in what he does. I really hope to still have something that mak

I mean overall, so that includes kernel crashes. Kernelwise, the main thing to report is a couple of crashes on non-mainline kernels like openVZ.

I'm one of of the sysdig creators. Sysdig is a pretty young project (we released it around a month ago), so I can't promise it will be flawless in a production environment. However, we've had many installations under severa

No, we don't use kprobes at this point, all of our collection is done through tracepoints. Take a look at https://github.com/draios/sysdig/blob/master/driver/main.c for details. They tend to be

Of course, we create and update the state by inspecting the incoming stream of system calls. We traverse proc only once, when you start a capture, and the reason to do that is collecting info for the PIDs/FDs that existed before we s

It looks like you don't have enough privileges to read /proc. Are you using this as root?

Brendan, thanks for the feedback. It's really cool to hear comments like this from someone like you. We really respect your work in the field. Good catch on topprocs_file, we'll have to find a better name for it. In terms of overh

The design is actually quite different. From the architectural point of view, sysdig is closer to tcpdump/wireshark than to systemtap/ktap. systemtap/ktap work similarly to dtrace: - a script is loaded into a user level proce

dtrace and any other instrumentation tool for linux require a kernel module as well. Ours has the advantage of being very simple and (in theory!) more stable, because decoding, filtering and scripting run at user level, so you have less cha

Thanks. To answer the question "what it does and how", 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 "packetiz
