AppImage run error about otel-profiling-agent

[athre0z]

Hmm, I probably shouldn't have fully stripped the build -- it's hard to make sense of the stacktrace now. Does the remote machine have a GPU and OpenGL installation? It's required for rendering on the machine running devfiler. Why are you running devfiler in this setup? Are you trying to profile a remote server? In that case I'd recommend to go with running it locally and forwarding the connection via a reverse SSH tunnel: there's an explainer on how to do that in devfiler's "Add data" dialog.

[athre0z]

What distribution are you running? Please paste output of

lsb_release -a

or, if that doesn't work

cat /etc/os-release

The error suggests that your system's installed glibc is older than what we currently support.

@athre0z one more question:
-collection-agent=: this param is the server addr which receive profile logs ? or only agent

[rockdaboot]

-collection-agent=: this param is the server addr which receive profile logs ? or only agent

It is the address (hostname/ip:port) of the receiving service (devfiler).

[ms2008]

I can't run it either. It's core dumped.

@ms2008 is this a pure Wayland setup without XWayland, by any chance? It looks like winit is failing to create a Window. Also, how are you running this? From a terminal within a desktop session?

[ms2008]

@athre0z Sorry, I do not have much knowledge of Wayland.

I'm not executing from a terminal in a desktop session, but from a terminal on a remote connection via ssh. Also, I have configured the DISPLAY environment variable and tried to forward X11 over SSH to run the program remotely and it still doesn't work.

I think I'm failing to understand this. I assumed after I install the agent I'll be able to see the data in Kibana and not some local GUI tool. Is this not the case or I'm misunderstanding?

When I try to start devfiler I get the following error:

I suppose its attempting to start the GUI, but I'm on a headless Ubuntu machine on AWS. Is it possible to start it without a gui and have that displayed in Kibana?

[athre0z]

The collection agent that is part of the Elastic stack currently does not yet support the OTel protocol implemented in the open-source variant of the profiling agent. You have two options here:

• Use our closed-source agent with an Elastic deployment and visualize data in Kibana. The closed-source agent is functionally equivalent to the open-source agent, except that it speaks our old proprietary protocol understood by the Elastic profiling collector. We are working on also teaching the Elastic collector to speak the new protocol, but it's not done yet.
• Run devfiler locally and tunnel port 11000 on your remote machine to your local machine with an ssh reverse tunnel.

For the latter variant, let me quote the documentation that is also displayed within the devfiler UI:

Profiling on remote hosts

A common use-case is to ssh into and run the profiling agent on a remote machine. The easiest
way to set up the connection in this case is with a ssh reverse tunnel. Simply run devfiler
locally and then connect to your remote machine like this:

ssh -R11000:localhost:11000 someuser@somehost

This will cause sshd to listen on port 11000 on the remote machine, forwarding all connections
to port 11000 on the local machine. When you then run the profiling agent on the remote and point
it to 127.0.0.1:11000, the connection will be forwarded to your local devfiler.
