STAP

NAME

stappaths - systemtap configurable file paths

DESCRIPTION

share/systemtap/tapset/

The directory for the standard probe-alias / function tapset library, unless overridden by the SYSTEMTAP_TAPSET environment variable or the XDG_DATA_DIRS environment variable. These are described in the stapprobes(3stap), probe::*(3stap), and function::*(3stap) manual pages.

share/systemtap/runtime/

The runtime sources, unless overridden by the SYSTEMTAP_RUNTIME environment variable.

bin/staprun

The auxiliary program supervising module loading, interaction, and unloading.

${prefix}/etc/stap-exporter

The default directory to search for *.stp files, for exporting to HTTP.

${exec_prefix}/libexec/systemtap/stapio

The auxiliary program for module input and output handling.

/usr/include/sys/sdt.h

Location of the <sys/sdt.h> headers.

Kernel debuginfo Path: /usr/lib/debug/lib/modules/$(uname -r)/

The location of kernel debugging information when packaged into the kernel-debuginfo RPM, unless overridden by the SYSTEMTAP_DEBUGINFO_PATH environment variable. The default value for this variable is +:.debug:/usr/lib/debug:build. elfutils searches vmlinux in this path and it interprets the path as a base directory of which various subdirectories will be searched for finding debuginfo for the kernel, kernel modules, and user-space binaries. By default, systemtap will also look for vmlinux in these locations:

/boot/vmlinux-`uname -r` 
/lib/modules/`uname -r`/vmlinux
/lib/modules/`uname -r`/vmlinux.debug
/lib/modules/`uname -r`/build/vmlinux
/lib/modules/`uname -r`/.debug/vmlinux.debug
/usr/lib/debug/lib/modules/`uname -r`/vmlinux.debug
/var/cache/abrt-di/usr/debug/lib/modules/`uname -r`/
/var/cache/abrt-di/usr/lib/debug/lib/modules/`uname -r`/vmlinux.debug

       Corresponding source files are usually located under /usr/src/debug/. Further file information on user-space applications can be determined per-basis using rpm -ql <package>-debuginfo. For supported user-space applications information please visit the systemtap wiki.

With elfutils version >0.178, systemtap can automatically download debugging information from debuginfod servers. You can try it by setting an environment variable or two:

export DEBUGINFOD_URLS=https://debuginfod.elfutils.org/
export DEBUGINFOD_PROGRESS=1

$HOME/.systemtap

Systemtap data directory for cached systemtap files, unless overridden by the SYSTEMTAP_DIR environment variable.

/tmp/stapXXXXXX

Temporary directory for systemtap files, including translated C code and kernel object.

/lib/modules/VERSION/build

The location of kernel module building infrastructure.

Examples with greater detail can be found here. Each example comes with a .txt or .meta file explaining what the example, sample or demo does and how it is ordinarily run. See also online at: https://sourceware.org/systemtap/examples/

$SYSTEMTAP_DIR/ssl/server

User's server-side SSL certificate database. If SYSTEMTAP_DIR is not set, the default is $HOME/.systemtap.

$SYSTEMTAP_DIR/ssl/client

User's private client-side SSL certificate database. If SYSTEMTAP_DIR is not set, the default is $HOME/.systemtap.

${prefix}/etc/systemtap/ssl/client

Global client-side SSL certificate database.

${prefix}/etc/systemtap/staprun/

staprun's trusted signer certificate database.

${prefix}/etc/sysconfig/stap-server

stap-server service global configuration file.

${prefix}/etc/sysconfig/stap-exporter

stap-exporter service global configuration file.

${prefix}/var/run/stap-server/

stap-server service default location of status files for running servers.

${prefix}/var/log/stap-server/log

stap-server service default log file.
