Package: cadvisor Version: 0.38.7+ds1-2 Severity: grave Tags: upstream Justification: renders package unusable X-Debbugs-Cc: ssingh+deb...@wikimedia.org
Dear Maintainer, The current version of cadvisor on Debian bullseye fails to gather process metrics because of a bug in the upstream version that results from bullseye defaulting to cgroup v2. This bug was fixed in https://github.com/google/cadvisor/pull/3030 by using the correct unified root path and accounting for the cgroup v2 change. The fix has not been backported but is available in the latest release of cadvisor. The current version of cadvisor in bullseye thus fails to gather metrics and other than a "Cannot detect current cgroup on cgroup v2" warning, there isn't any indication to the user. Backporting the specific patch will not work as the version in Debian is outdated: the latest cadvisor version at the time of writing this is 0.46.0 and was released in November 2022 with the above fix, whereas 0.38.7 was released in January 2021 and these two versions have deviated significantly. The only way to make the current version of cadvisor work is to set systemd.unified_cgroup_hierarchy=0 to enable the hybrid/legacy cgroup mode but that's not desirable, and thus perhaps, a new release of the cadvisor package is warranted. Thank you for your time. -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 5.6.0-1-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_WARN, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages cadvisor depends on: ii libc6 2.36-6 ii libzstd1 1.5.2+dfsg-1 cadvisor recommends no packages. cadvisor suggests no packages.
