Missing debug symbols for perf analysis on process inside docker container
trafficstars
It is very likely that this is not a bug, but rather a problem on my side. As I did not find a forum or mailing list to ask my question, I emailed Milian Wolff and he kindly suggested me to post my problem as an issue on GitHub, hence why it is posted here.
I would like to do some performance analysis using hotspot on a process that is running inside a Docker container. I collect my perf data on the host (not in the docker container!) as follows:
sudo perf record --call-graph dwarf -p <pid-on-host>
where <pid-on-host> is the process ID on the host of the process I'm interested in (the process is /usr/sbin/sabine inside the docker container and there it has another PID).
Using docker ps to find the ID of my docker container, and then docker inspect as follows:
bvandewoestyne@BVANDEW-70TZQ73:~/projects/virtual_ngp_network/docker_files$ docker inspect 9347ec238188 | grep MergedDir
"MergedDir": "/var/lib/docker/overlay2/0cf422ea6e341c992254d2221c77f3211629e546b44c9a46cf2e9b01654bc38a/merged",
I search for the directory that has the same contents as the root filesystem of my docker container, so that I can pass that to the --sysroot option of hotspot so that all symbols can be found.
Then, I start hotspot with the --sysroot option as follows:
sudo /home/bvandewoestyne/bin/hotspot-v1.4.1-x86_64.AppImage --sysroot=/var/lib/docker/overlay2/0cf422ea6e341c992254d2221c77f3211629e546b44c9a46cf2e9b01654bc38a/merged perf.data
I need sudo to access the merged directory.
I get the following errors in my terminal:
bvandewoestyne@BVANDEW-70TZQ73:~/projects/virtual_ngp_network/docker_files$ sudo /home/bvandewoestyne/bin/hotspot-v1.4.1-x86_64.AppImage --sysroot=/var/lib/docker/overlay2/0cf422ea6e341c992254d2221c77f3211629e546b44c9a46cf2e9b01654bc38a/merged perf.data

and more importantly, in hotspot I see that for sabine I have lots of missing debug symbols and I see a lot of question marks in the flamegraph:
For as far as I know, my sabine binary has debug info in it, as can be seen with file (notice the with debug_info in the output):
bvandewoestyne@BVANDEW-70TZQ73:~/projects/virtual_ngp_network/docker_files$ sudo file /var/lib/docker/overlay2/0cf422ea6e341c992254d2221c77f3211629e546b44c9a46cf2e9b01654bc38a/merged/usr/sbin/sabine
/var/lib/docker/overlay2/0cf422ea6e341c992254d2221c77f3211629e546b44c9a46cf2e9b01654bc38a/merged/usr/sbin/sabine: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=b99b1e91087b5c7bbed0b2f71f819c5dbef11e9d, with debug_info, not stripped
Would you have any idea why I still have these missing debug symbols in hotspot? Or any idea how to diagnose this further?
Some info of my host system:

PS: a similar question has been asked here (but not answered): https://stackoverflow.com/questions/71685770/profile-a-process-inside-a-container-from-host-using-perf
I definitely have done something along those lines some years ago, but I don't have that setup available to me anymore so I don't know for sure what steps I did.
But debugging this should be relatively straight forward:
sudo strace -e file -f /home/bvandewoestyne/bin/hotspot-v1.4.1-x86_64.AppImage --sysroot=/var/lib/docker/overlay2/0cf422ea6e341c992254d2221c77f3211629e546b44c9a46cf2e9b01654bc38a/merged perf.data |& grep sabine
This should show you where hotspot or perfparser try to access the sabine binary. Please paste it here so we can check what's happening.
Also, to cross-check: You can setup docker to allow launching graphical applications therein. Can you try to do that and run the AppImage within the docker container to check whether that works better? It shouldn't be needed, but it would give us a second view into this problem.
Should the GUI popup fast under that strace command? Because when I run it, I don't get any grep output. After waiting for 5 minutes, I was still stuck at
$ sudo strace -e file -f /home/bvandewoestyne/bin/hotspot-v1.4.1-x86_64.AppImage --sysroot=/var/lib/docker/overlay2/86aa800d14f4efdfabc0110938bf67ef8c9697423bc8a4b8168ad68d7bb3062e/merged perf.data |& grep sabine
without any output. I see the following processes are running:

Does that give any insight?
Yes, it finds some cached data over at

which is probably wrong for the given buildid?
You can try to workaround this by passing an explicit --debugPaths and/or --appPath to hotspot which points into your sysroot.
But ideally you also test the latest appimage (see e.g. https://github.com/KDAB/hotspot/actions/runs/6335963163 ) and see if that one works better. If not, then there's clearly a bug here - we shouldn't try to load this file outside the sysroot imo.
Using the latest AppImage hotspot-v1.4.1-175-gfaf33ed-x86_64.AppImage, when I run with only the --sysroot option as
sudo ~/bin/hotspot-v1.4.1-175-gfaf33ed-x86_64.AppImage --sysroot=/var/lib/docker/overlay2/20dbe9864fa8531dc0c27929dd78e7112aa0edba84e339b99722a495c40233ff/merged perf.data
then I get the following parse errors:
Notice that for
sabine the symbols were not found.
When I run with both the --sysroot and --debugPath options as
sudo ~/bin/hotspot-v1.4.1-175-gfaf33ed-x86_64.AppImage --sysroot=/var/lib/docker/overlay2/20dbe9864fa8531dc0c27929dd78e7112aa0edba84e339b99722a495c40233ff/merged --debugPaths=/var/lib/docker/overlay2/20dbe9864fa8531dc0c27929dd78e7112aa0edba84e339b99722a495c40233ff/merged perf.data
Then the sabine symbols are found, which is already good, but apparently then the "kernel symbol mapping file" cannot be found/parsed:
Important sidenote: colleagues of me have done the same test (on both Ubuntu 20 and 22) and for them the sabine symbols were found without using the --debugPaths option, only using the --sysroot option... which still puzzles me...
So my problem is solved in the sense that the sabine debugsymbols are found when using the --debugPath option, but it would be nice if I could also get rid of the other parse errors.
Also, does this give you enough information to know whether this is a bug or not? Is there anything else you want me to test or verify?
Can you please strace again with the latest appimage and paste an update situation, for when you only pass --sysroot?
Ten, can you try and see what happens when you clear your local /root/.debug/ path? Strace again and paste, as well as describe whether that changes any behavior.
Regarding the kernel symbol mapping file: you will have to specify that one manually via --kallsyms /proc/kallsyms, as it's not part of your sysroot.
Sorry for the late reply... it's been kinda busy here at work ;-)
I don't know why, but trying to strace with the latest appimage doesn't seem to work. If I try
bvandewoestyne@BVANDEW-70TZQ73:~$ sudo strace -e file -f /home/bvandewoestyne/bin/hotspot-v1.4.1-191-gc795618-x86_64.AppImage --sysroot=`docker inspect -f '{{.GraphDriver.Data.MergedDir}}' docker_files_ins_200_113_chassis_1_inet_1_terminal_1_1` perf.data |& grep sabine
then my hotspot GUI doesn't start and I also don't see strace output in my terminal. It simply seems to 'hang'. Do you have any idea why? Probably has to do with the fact that its an AppImage...
With the hotspot version that I can install as a package on my Ubuntu Ubuntu 20.04.6 LTS, which is:
bvandewoestyne@BVANDEW-70TZQ73:~$ hotspot --version
hotspot 1.1.0
I get:
bvandewoestyne@BVANDEW-70TZQ73:~$ sudo strace -e file -f hotspot --sysroot=`docker inspect -f '{{.GraphDriver.Data.MergedDir}}' docker_files_ins_200_113_chassis_1_inet_1_terminal_1_1` perf.data |& grep sabine

In the second case, the sabine symbols were shown in the hotspot gui! So it looks like it indeed has to do with this /root/.debug directory... Not sure though whether this is a bug or a problem on my side (with the /root.debug directory).
Does this info help? Or do you want me to test other things?
