2018-02-20Fix regression introduced in d468fcbb / OTP-14816John Högberg
The ~p format specifier made file:consult/1 hysterically slow on one of our test machines that had a unicode character in the root of the code path; all paths were printed as lists and indented with way too much whitespace. Using ~w avoids this issue by never indenting.

2018-01-11Reduce memory use of system_information:to_file/1John Högberg
The previous implementation generated a term, converted it to plain text with io_lib:format/2, and then converted that to a binary before writing it to disk. We now emit the term as we go, which should make it a bit safer to extract this information under load.
2017-12-19Turn on scheduler_wall_time in an alive processDan Gudmundsson
scheduler_wall_time is ref-counted so it will turn off if process dies, keep the process that turns it on alive.

2017-03-27Add a no_native option wherever there is an on_loadKostis Sagonas
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.

2016-05-24erts: Move tracer SecondTraceTerm to Opts mapLukas Larsson
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.
2016-05-20[runtime_tools] Don't trace the trace client portSiri Hansen
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.
