Various scripts using systemtap for analysis and diagnostics. This is inspired by nginx-systemtap-toolkit but scripts are written in Python instead of Perl.
You need at least systemtap 2.3. Maybe it works with less recent
version but I did not test them. You also need Python 2.7. For most
scripts, you should ensure that the appropriate DWARF debuginfo have
been installed. For Debian, this means to either install -dbg
package or install from source without stripping debug symbols. For
Ubuntu, you can use dbgsym packages.
You need at least Linux kernel 3.5 with uprobes API for userspace tracing. A reasonable setup for Ubuntu Precise is the following one:
$ apt-get install linux-image-3.11.0-13-generic{,-dbgsym}
$ apt-get install linux-headers-3.11.0-13-generic
$ apt-get install make gcc
Previous kernels are missing important symbols. Ubuntu Precise has a
buggy GCC which is not able to handle kernels using -mfentry
flag. You can workaround this by setting PR15123_ASSUME_MFENTRY
environment variable to 1 with systemtap 2.4.
Running systemtap-based tools requires special user permissions. To
prevent running these tools with the root account, you can add your
own (non-root) account name to the stapusr and staprun user
groups. But it is usually easier to just use sudo.
Each script comes with appropriate help. Just run it with --help to
get comprehensive help with examples.
Some tools are emitting warnings:
untested: not really testedbuggy: can crash or produce no results
