Show the statistics, limits and percentage for atoms, processes,ports and ETS.
Backward compatibility with old versions, In case the valuse is missing it shows
the string Not available.

Encoding specified in a comment must be 'utf-8' instead of 'utf8'.

This is a poor man's solution that allows to build and test the
system with all files compiled to native code simply by setting
the ERL_COMPILER_OPTS environment variable. Better solutions,
like automatically setting the no_native option whenever the
compiler sees an on_load attribute, obviously exist but require
more time to implement.

Since commit 265998a7e412cd382315632964846569c370a5a2, etop reports
the CPU (scheduler) utilization since the tool was started instead of
for the last interval only. This is now corrected.

This sets the maximum queue size for the IP trace driver which is used
when tracing to shell and/or <c>{local,File}</c>.
Also, change the default queue size set by dbg:trace_port/2 to 200.

runtime_tools: Fix erl_tracer testcases
runtime_tools: Fix documentation for dbg:p
erts: Move tracer SecondTraceTerm to Opts map
|
|
The extra trace data has been moved to the opts map in order
for the tracer to be able to distinguish inbetween extra
trace data 'undefined' and no extra trace data. In the same
commit all opts associations have been changed so that if
the tracer should not use them, the key is left unassicated
instead of being sent to undefined. This should be give a
small performance gain and also makes the API easier to work
with.
|
|
When using an IP trace client, turn of all trace flags on the client
port to avoid massive overload. Note that this is only a protection on
client start - it is currently not possible to protect the port
against trace flags set at a later point in time.

i.e enable all send/receive trace.
|

To set/clear match specs for send and receive trace.
'e' for Event as we might want to add match specs
for other trace events (proc exit,link,ulink,...).

Using the new type syntax, we can specify which keys are required, and
which are optional in a way Dialyzer could use.
|
|
system_information calls could timeout in certain debug scenarios.

This commit completes the tracing for processes so that
all messages sent by a process (via nifs or otherwise) will
be traced.
The commit also adds tracing of all types of events from ports.
When enabling tracing using erlang:trace, the 'all' flag now also
enables tracing on all ports.

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.
Since checking whether microstate accounting is on or off is
relatively expensive if done in a short loop only a few of the
states are enabled by default and more states can be enabled
through configure.
I've done some benchmarking and the overhead with it turned off
is not noticible and with it on it is a fraction of a percent.
If you enable the extra states, depending on the benchmark,
the ovehead when turned off is about 1% and when turned on
somewhere inbetween 5-15%.

Trace files are typically large but contain small terms so we can expect
a performance gain from read buffering. dbg:trace_client with a dummy
handler ran more then 3x faster on a sample 200MB trace file.
fprof:profile can also gain a bit.
