Linux performance and analysis tools

fustini

Handy graphic I saw on Google+ and thought might be interesting to those running Linux on SBCs:

 

Linux performance and analysis tools

Anything that is missing?  or anything that is wrong?

  • perf seems to have become the 'swiss army knife' for analysing all sorts of stuff in linux.

     

    The one I'd probably question is netstat. The linux networking stack is actually very much more capable than tools like netstat can describe. You'd want to use things like ctstat, rtstat, ifstat, lnstat, nstat, rtacct, ss from the iproute2 package to get a better view of what's going on.

     

    Similarly, it's missing things like mtr, traceroute, tracepath, tcptraceroute on the network side and I'm sure there are many others.

     

    Possibly not directly applicable to SBC's, but there's things like powertop and tools/x86/turbostat in the kernel source that any Arm equivalents of would be interesting to use to analyse what pointless things the system is wasting power on.

     

    The list will probably get huge - depends on exactly what things you want to examine..
