-# Lint as: python2, python3
-"""
-Trace kernel events with Linux Tracing Toolkit (lttng).
-You need to install the lttng patched kernel in order to use the profiler.
-
-Examples:
- job.profilers.add('lttng', tracepoints = None): enable all trace points.
- job.profilers.add('lttng', tracepoints = []): disable all trace points.
- job.profilers.add('lttng', tracepoints = ['kernel_arch_syscall_entry',
- 'kernel_arch_syscall_exit'])
- will only trace syscall events.
-Take a look at /proc/ltt for the list of the tracing events currently
-supported by lttng and their output formats.
-
-To view the collected traces, copy results/your-test/profiler/lttng
-to a machine that has Linux Tracing Toolkit Viewer (lttv) installed:
- test$ scp -r results/your-test/profiler/lttng user@localmachine:/home/tmp/
-Then you can examine the traces either in text mode or in GUI:
- localmachine$ lttv -m textDump -t /home/tmp/lttng
-or
- localmachine$ lttv-gui -t /home/tmp/lttng &
