stappaths - systemtap configurable file paths
This manual page was generated for systemtap 4.8. The following section will
list the main paths in systemtap that are important to know and may be
required to reference.
- /usr/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.
- /usr/share/systemtap/runtime/
- The runtime sources, unless overridden by the
SYSTEMTAP_RUNTIME environment variable.
- /usr/bin/staprun
- The auxiliary program supervising module loading,
interaction, and unloading.
- /etc/stap-exporter
- The default directory to search for *.stp files, for
exporting to HTTP.
- /usr/lib/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.
- /usr/share/doc/systemtap*/examples
- 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.
- /etc/systemtap/ssl/client
- Global client-side SSL certificate database.
- /etc/systemtap/staprun/
-
staprun's trusted signer certificate database.
- /etc/sysconfig/stap-server
- stap-server service global configuration file.
- /etc/sysconfig/stap-exporter
- stap-exporter service global configuration file.
- /var/run/stap-server/
- stap-server service default location of status files for
running servers.
- /var/log/stap-server/log
- stap-server service default log file.
