otel-profiling-agent's Issues

failed to load unwind_stop

I tried to run it, but the program reported an error.
I tested on three different kernels and found that this issue exists in all of them.

can't I see the Java call log run in the environment of wsl2

Linked binary in dev-filer does not work on Mac (m1)

./pf-host-agent
zsh: exec format error: ./pf-host-agent

Ubuntu, sudo make docker-image failed.

I tried to run sudo make docker-image on my Ubuntu 22.04.3 LTS, but failed at "returned a non-zero code: 100".

After an investigation, I found that it is due to these commands in Dockerfile

"RUN apt-get update && apt-get dist-upgrade -y ..."

I didn't find any solution for that. Could you confirm it?

Thank you.

java questions

I want to know if I can get the specific value entered by the user in the java program

Is there any otel collector version that supports this new feature?

I tried to run my own otel collector to collect the data, however, it shows that some of the new features of signal is not implemented.

Reading incorrect java version

Description

With an OpenJDK 22 temurin, I am getting strange versions readings.

level=error msg="Failed to handle new anonymous mapping for PID 1422866: JVM version 0.127.69+8 (minimum is 7)"

Additional information

There seems to be different layouts depending on versions, 21, 8.

unable to open /proc/sys/kernel/bpf_stats_enabled

Describe

When running the profiling agent

How to reproduce ?

The machine kernel version was originally 3.10, but the agent supports a minimum kernel version of 4.19, so the machine kernel was upgraded

However, I found that there is no /proc/sys/kernel/bpf_status_enabled after the upgrade

This kernel parameter is only available in the 5.1 kernel

What did you expect to see?

I want to run the agent successfully on a kernel 4.19 machine

Environment (please complete the following information)

Failure to compile ebpf on aarch64

The following works on x86_64, but fails on aarch64:

$ make docker-image
$ docker run --rm -it -v $(pwd):/agent -w /agent/support/ebpf --entrypoint /bin/bash profiling-agent
# make tsd.ebpf.o

The error from aarch64:

[Feature Request]A copy-to-clipboard button for the download link of the agent

On Linux, the above link cannot be selected, so one cannot copy it to clipboard, which is quite inconvenient, it would be really great if we can have a copy-to-clipboard button just like the buttons for the below commands:)
