| Userspace utilities for the LTTng 2.x tracing |
| infrastructure. |
| |
| Those utilities are required on the target system to start |
| and stop tracing sessions. Analysis of the trace can be done |
| on the host machine using the babeltrace utility. This |
| utility is automatically built by Buildroot in |
| $(O)/host/usr/bin/babeltrace, as a dependency of |
| lttng-tools. However, there is also a lttng-babeltrace |
| package for the target, if babeltrace on the target is |
| interesting. |
| |
| If userspace tracing is desired, you need to enable |
| lttng-libust. |
