Trying to run this from PowerShell it just failed silently with no message. From cmd.exe, I got a popup saying "The code execution cannot proceed because VCRUNTIME140.dll was not found. Reinstalling the program may fix this problem." We should probably document that requirement somewhere, if we can't otherwise fix it (does CPython not have the runtime?!).

This is pretty self explanatory, but code runtimes show with many decimal places on the UI. It would be nice to show only to the closest nanosecond or microsecond (perhaps this could be user selectable).

How to read the graph? Explanations and legend of the signs in the graph can be very useful!

I.e. what is dotted line? what is dashed line? what are the number means? what are the boxes(n the end of the tree) means?

Also- improving the labels/captions(title when hovering a dom item) can be very useful

When profiling openalpr, the profile.coz file (named profile.txt in the attachment to keep github editor happy) show that a lot of time is spent in locations in /usr/include/c++/4.9/bits/stl_vector.h and /usr/include/opencv2/core/mat.hpp (matrix operations). This is not really helpful without knowing from where the STL vector or the matrix operation is used. Perhaps Coz should be adjusted to col

The longer data is collected, the more the graph gets compressed. It would be nice to have a UI like this, where you can select the time span you'd like to look at from "1h" to "All" (screen shot taken at satstuscake.com):

Would be awesome if we could use Remotery to profile C/C++ emscripten games.

Challenges:

1. Websocket server. We can't start a websocket server from an emscripten game. One workaround is to use a native websocket server as a proxy. Another solution is have emscripten directly send the data to another browser tab (postMessage)

2. Timer accuracy. Browsers have recently reduced the accurac

Hi there

I'm trying to install xhprof +xhgui, but something is not working with mongoDB. After a full setup, when I browse a page on my project, I'm getting errors in apache logs saying:

xhgui - document to insert contains invalid key: keys cannot contain ".": "main()==>load::myprojecttoprofile/index.php"

(I haven't been able to find any similar ticket issues for xhgui on this specific

May be I am just misusing the tool, but I feel like this is a bug:

So I profile an app, I filter the main thread and look at the flame graph and get this (which looks wrong):

I then select a range in the timeline view (a very useful feature btw, thanks a lot f

The profile binary format for version v2.1.0 appears to have changed to accommodate bookmarks but there is no accompanying documentation in the wiki.

No requirement information is available on the project documentation (README nor wiki). Even if the project has no requirement, this information is important for sysadmins and should be written down.

Could you please add a requirements section in the README file ?
And add info about version numbering being aligned with the runtime support as explained in #878

Current: No list / command of OS dependencies are indicated prior to attempting to 'make' the application.

Desired: List OS packages / Add command examples to install.

Example: For Ubuntu 18.0x autoconf bison flex gawk git liblzma-dev libbz2-dev make python zlibc zlib1g zlib1g-dev

Thank you.

Repro:
Press RMB to scroll thread timeline.
Thin black rectangles from the previous hover is left after scrolling.

Code is here: ThreadView.xaml.cs
We need to disable hover if we are scrolling the timeline.

Because advanced profiling working since api 26 and above users can forgot about enabling and get failed build error com.android.builder.dexing.DexArchiveBuilderException: Failed to process
In this case they must:
Edit Configurations -> app -> Profiling tab -> uncheck Enable advanced profiling

For example correlation between capture and sampling/callstacks; I'd like to be able to right-click on a hooked function listed in the capture and "go to" it in the sampling view automatically

Enabling debug, shows

CPU profiler is only supported on Linux and OS X.

which is the main thing I would expect from a profiler... So maybe add a warning that this can't be used on windows as people would normally understand it.

We can get better info about the type parameters that were monomorphized, which should make it much easier to debug this stuff.

Therefore, we should suggest building with RUSTFLAGS=-Zsymbol-mangling-version=v0 in the twiggy monos section and also probably the "concepts > monomorphizations" section.
