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.

* lukas/erts/tracing/tracer-move-extra-to-map/OTP-10267: runtime_tools: Fix erl_tracer testcases runtime_tools: Fix documentation for dbg:p erts: Move tracer SecondTraceTerm to Opts map
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.

2016-02-02erts: Add microstate accountingLukas Larsson
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%. OTP-12345
2016-01-28Use file read buffering in dbg:trace_clientPéter Gömöri
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.
