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).

Right now, 0B:256B is interpreted at a range for filtering tags, but 0:256B is not.

I think we should either infer that the units are the same for both parts of the range if units are only specified for one half of the range, or not require units for zero.

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

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

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

Summary:

This ticket is a suggestion for improving the documentation by adding a description of the metrics collected by the profiler.

Details:

As noted in uber-common/jvm-profiler#50, there is currently no documentation describing the metrics that are collected.
Adding a description of what each collected metric represents to the documentation m

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.

Hello! I’ve looked at the Usage Guide (both the wiki page and the PDF) but neither of them explain how to get started. They both assume that the user already knows how to obtain and run OpenCover. I’ve added the OpenCover nuget package to my solution but I could not figure out how to go from there. The Usage Guide talks about a “console application” but there is no console application anywhere tha

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.

This was @krakjoe 's idea.

I think we have a head start on this as the tracing code is already decoupled with the event handling code. See:

https://github.com/adsr/phpspy/blob/e9927c8e7a8cdf6763d163bfaa60cec313cb37c0/phpspy.c#L262

Maybe we write an event_lua.c that is end-user scriptable?

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:

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.
