flameviewer's Issues

Text on flamegraph is blurry on MacBook

Uploading a jfr resulted in versionNotSupportedException

Hi Team,

While uploading a jfr generated from Zulu Openjdk in MacOS using chrome, we got the below listed exception

Show detailed error message to user when conversion failed

Add time or counter of a call to its popup

Text on rectangles is shifted to the top on Fedora

Seems like needed font is missing

Check if the same stacktraces are merged together in .flamegraph files

Maybe it should be done only when file is uploaded

Scroll to the left when new thread is open on Call Tree page

Thread call-tree is not scrolled to the beginning if other thread was open before

Possible to display time in flame graph?

Is there a concept of time (relative or absolute) available to display in the Call Traces or Back Traces?

Right now I'm going off of relative stack widths to find slow code to optimize. However, when I fix one slow section of code, it's hard to get a picture of how much time was saved.

Extract time from jfr files

Currently number of stack traces is saved. It should be replaced with time in milliseconds

Make FlameViewer a standalone tool

Move Fierix to a separate project
Startup FlameViewer from command line with a path to file (one FlameViewer instance per file)
FlameViewer in plugin must not lose uploaded files. It should keep files storage and convert files to cflamegraph

Method time on back traces page does not match time on hotspots page

Native perf support

Unable to upload a jfr file reading

While uploading a jfr file reading a pop up comes up and says file was not sent.

Add option to upload yourkit snapshot without exporting it to csv

No call was registered or all methods took <1ms

What should I try when all results I ever get are "No call was registered or all methods took <1ms" instead of a flame graph?

This is the beginning of the log output in the IJ console:

Can I find/add any other debug log info?

Implement Level of Detail instead of hiding top layers of tree

To improve performance FlameViewer shows only limited number of nodes to user. Currently it's implemented by hiding top levels of tree.
It's better to hide smallest nodes instead.

Use FlatBuffers for cflamegraph files

Snapshot version of plugin implements compressed version of flamegraph format.
But the new format is not binary therefore it is not optimal for saving disk space.
Also custom parser is implemented for the format and it is bug prone.

I suggest keeping structure of cflamegraph files but using FlatBuffers for serialization.

cflamegraph format will contain the same amount of information as regular flamegraph, therefore it will not be possible to directly use it for client-server communication #15, but it can be easily converted to more complex data.

I considered making cflamegraph format to be also client-server format, but then it would contain redundant information (that is set to speed up visualization) also client-server format may be changed and I do not want to worry about support for existing files.

Convert `jfr` files to `cflamegraph` instead of `flamegraph`

JMCConverter should implement ProfilerToCompressedFlamegraphConverter instead of ProfilerToFlamegraphConverter

When I click to Tools>Flamegraph Profiler>Upload File Browser opened just with 404 not found message.

@kornilova-l The url form is like below.

I already profiling using Run with Flamegraph profiler. And also I checked ser file generated normally.
After finish profiling I wanted saw Flamegraph so I clicked Upload File menu.
But I just could saw 404 Not Found message with IntelliJ IDEA 2017.3.3 message under line.

Start using FlatBuffers instead of Google Protobuf

Start using Cap'n Proto instead of Google Protobuf for client-server communications. This will speed up visualization and reduce memory consumption.

Filter multiple packages?

Is it possible to filter multiple packages at the same time?
It looks like the filtering is handled in Filter.kt, using Regex behind the scenes. Looks like adding a bar ('|') between packages works, but I wanted to make sure this is the correct way to filter.

If this is correct, would a note on this in the README be accepted if I submit a PR with an example?

This is a wonderfully powerful tool. Thank you for writing this excellent piece of software!

FlameViewer ask for password?

Can I ask what username and password?

lang.LinkageError: loader (instance of sun/misc/Launcher$AppClassLoader): attempted duplicate class definition for name: ""

How to fix this error?

Split plugin into two plugins, so it would be possible to view flamegraphs in all IDEs

Cannot upload a file using firefox
