This is the Linux Trace Toolkit. Included in this package: Command-line client: lttng Tracing daemons: lttng-sessiond (automatically started by lttng) lttng-relayd (remote trace collection daemon) Userspace tracing can be done by using liblttng-ust. To do kernel tracing we also need the LTTng kernel modules. I've added a patch that changes "/sbin/modprobe" to just "modprobe".
