Using SystemTap

This chapter instructs users how to install SystemTap, and provides an introduction on how to run

SystemTap scripts.

To deploy SystemTap, you need to install the SystemTap packages along with the corresponding set

of -devel, -debuginfo and -debuginfo-common packages for your kernel. If your system has

multiple kernels installed, and you wish to use SystemTap on more than one kernel kernel, you will

need to install the -devel and -debuginfo packages for each of those kernel versions.

These procedures will be discussed in detail in the following sections.

Important

Many users confuse -debuginfo with -debug. Remember that the deployment of

SystemTap requires the installation of the -debuginfo package of the kernel, not the -

debug version of the kernel.

To deploy Systemtap, you will need to to install the following RPMs:

• systemtap

• systemtap-runtime

Assuming that yum is installed in the system, these two rpms can be installed with yum install

systemtap systemtap-runtime. Note that before you can use SystemTap, you will still need to

install the required kernel information RPMs.

SystemTap needs information about the kernel in order to place instrumentation in it (i.e. probe it).

This information also allows SystemTap to generate the code for the instrumentation. This information

is contained in the matching -devel, -debuginfo, and -debuginfo-common packages for your

kernel. The necessary -devel and -debuginfo packages for the ordinary "vanilla" kernel are as

follows:

• kernel-debuginfo

• kernel-debuginfo-common

• kernel-devel

Likewise, the necessary packages for the PAE kernel would be kernel-PAE-debuginfo, kernel-

PAE-debuginfo-common, and kernel-PAE-devel.

To determine what kernel your system is currently using, use:
