| 6 | The _Linux Trace Toolkit: next generation_ is an open source software |
| 7 | toolkit used to simultaneously trace the Linux kernel, user applications, |
| 8 | and user libraries. LTTng consists of <<lttng-modules,kernel modules>> |
| 9 | (for Linux kernel tracing) and dynamically loaded |
| 10 | <<lttng-ust,libraries>> (for user application and library tracing). |
| 11 | A <<lttng-sessiond,session daemon>> controls the LTTng tracers after it |
| 12 | receives commands from the <<lttng-cli,cmd:lttng command-line |
| 13 | tool>>. |
