| 5 | **LTTng** is a set of software components which interact to allow | |
| 3d43c138 PP |
6 | instrumenting the Linux kernel and user applications as well as |
| 7 | controlling tracing sessions (starting/stopping tracing, | |
| 8 | enabling/disabling events, and more). Those components are bundled into | |
| 9 | the following packages: | |
| 5e0cbfb0 | 10 | |
| 3d43c138 PP |
11 | * **LTTng-tools**: libraries and command line interface to control |
| 12 | tracing sessions. | |
| 13 | * **LTTng-modules**: Linux kernel modules for tracing the kernel. | |
| 14 | * **LTTng-UST**: user space tracing library. | |

| 16 | Most distributions mark the LTTng-modules and LTTng-UST packages as | |
| 3d43c138 PP |
17 | optional. In the following sections, the steps to install all three are |
| 18 | always provided, but note that LTTng-modules is only required if | |
| 5e0cbfb0 PP |
19 | you intend to trace the Linux kernel and LTTng-UST is only required if |
| 20 | you intend to trace user space applications. | |

| 22 | This chapter shows how to install the above packages on a Linux | |
| 23 | system. The easiest way is to use the package manager of the system's | |
| 251b1286 | 24 | [distribution](#doc-desktop-distributions). Embedded distributions |
| 5bdc4885 PP |
25 | (Buildroot and OpenEmbedded/Yocto) currently have no packages of |
| 26 | LTTng 2.7 (LTTng 2.6 is available for both of them). Support is also | |
| 27 | available for | |
| 88e1a92d PP |
28 | [enterprise distributions](#doc-enterprise-distributions), such as |
| 29 | Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES). | |
| 30 | Otherwise, you can | |
