(SOLVED) Can not open Web Profiler

Questions
1

When my project is running, Open Web Profiler and Open Resource profiler buttons do nothing. No errors in console or logs. But if I go to localhost:8002, resource profiler is there. Is there a fixed port for web profiler or what can I do to spot the issue? Defold 1.6.4 and Linux. Here logs from console:

INFO:DLIB: Log server started on port 40665
INFO:ENGINE: Target listening with name: yoga7 - 127.0.1.1 - Linux
INFO:ENGINE: Engine service started on port 46035
INFO:GRAPHICS: Installed graphics device 'ADAPTER_FAMILY_OPENGL'

Odd that there is nothing in the editor log? Did you check both the console and the editor log file?

The ports are documented here: https://github.com/defold/defold/blob/dev/engine/docs/DEBUG_PORTS_AND_SERVICES.md

The 8002 port is a fixed redirect port which redirects the request to the actual port. Do you perhaps have something which blocks this redirect?

And this is the code for opening the profiler:

Ah, this now rings a bell. There is an issues for this already:

It is likely that your OS for some reason doesn’t indicate that the java.awt.Desktop.Action.BROWSE is supported. Perhaps you don’t have a default browser set?

@britzl Thank you for the answer. After a bit of investigation I think this is a KDE specific issue. There are a bunch of questions on stackoverflow about this:

all related to KDE Plasma. I have default browser set, but seems like java.awt.Desktop.Action.BROWSE uses gnome specific functions to open links and it’s generally advised to use xdg-open instead on linux. So I think all KDE users affected by this.
I’ve tried all suggested workarounds without luck. Actually I don’t mind to open profiler manually, but I can’t figure out what url I should use.

I’m getting redirected, but there is only resource profiler shown.

The idea is that the editor should start a webserver, serving some content, and that the engine can connect to it.

As a workaround, you can run the server manually yourself, using the source from here:
Remotery/vis

Run it using python3 -m http.server in that directory.
Then access your http://localhost:8000 for the profiler.

In that profiler, it should show the profiling of your current running session (default address/port is ws://127.0.0.1:17815/rmt)

I’ve figured it out! When editor starts, there is a line in logs:

[JavaFX Application Thread] INFO  util.http-server - {:line 103, :msg "Http server running", :local-url "http://localhost:34241"}

One need to take an url from the line and full path to the profiler will be:

http://localhost:34241/engine-profiler

@britzl Thank you a lot for pointing to editor source code. I will mark this topic as solved, but ideally something should be done about this. Just print path to profiler in console would be quick workaround. Anyway it’s pretty cool to have such a quick support from Defold team members, I’m impressed!

Thank you for the idea. If I understood correctly, server is started successfully and I just need to figure out what port it occupies. I’ve described a workaround in a post above. :handshake:
