- Add microstate accounting</p>
- <p>
- Microstate accounting is a way to track which state the
- different threads within ERTS are in. The main usage area
- is to pin point performance bottlenecks by checking which
- states the threads are in and then from there figuring
- out why and where to optimize.</p>
- <p>
- Since checking whether microstate accounting is on or off
- is relatively expensive only a few of the states are
- enabled by default and more states can be enabled through
- configure.</p>
- <p>
- There is a convinence module called msacc that has been
- added to runtime_tools that can assist in gathering and
- interpreting the data from Microstate accounting.</p>
- <p>
- For more information see <seealso
- marker="erts:erlang#statistics_microstate_accounting">erlang:statistics(microstate_accounting,
- _)</seealso> and the <seealso
- marker="runtime_tools:msacc">msacc</seealso> module in
- runtime_tools.</p>

- Update dbg and ttb to work with a tracer module as tracer
- and tracing on ports.</p>
- <p>
- Own Id: OTP-13500</p>

- <p>
- Updated dbg to accept the new trace options
- <c>monotonic_timestamp</c> and
- <c>strict_monotonic_timestamp</c>.</p>

- Introduce LTTng tracing via Erlang tracing.</p>
- <p>
- For LTTng to be enabled OTP needs to be built with
- configure option <c>--with-dynamic-trace=lttng</c>.</p>
- <p>The dynamic trace module <c>dyntrace</c> is now
- capable to be used as a LTTng sink for Erlang tracing.
- For a list of all tracepoints, see <seealso
- marker="runtime_tools:LTTng">Runtime Tools User's
- Guide</seealso> .</p>
- <p>This feature also introduces an incompatible change in
- trace tags. The trace tags <c>gc_start</c> and
- <c>gc_end</c> has been split into <c>gc_minor_start</c>,
- <c>gc_minor_end</c> and <c>gc_major_start</c>,
- <c>gc_major_end</c>.</p>
