can you add --log-level=debug and report it? Is this a RHEL7 issue, does cpuacct.usage_sys exists? Do we need to toggle something in the kernel to turn on accounting? /sys/fs/cgroup/cpuacct/machine.slice/libpod-c191203a03972ccd8423f392674722451417b7dff0df694e2f02b8254cd28aa2.scope/cpuacct.usage_sys it seems the kernel is missing the patch for having user_usage and sys_usage. I'll need to account for it in pkg/cgroups I've added a patch to https://github.com/containers/libpod/pull/3506 to address this issue. Hi Brent, This is the output from podman with --log-level debug: # podman --log-level debug stats --all --no-stream DEBU[0000] Initializing boltdb state at /var/lib/containers/storage/libpod/bolt_state.db DEBU[0000] Using graph driver overlay DEBU[0000] Using graph root /var/lib/containers/storage DEBU[0000] Using run root /var/run/containers/storage DEBU[0000] Using static dir /var/lib/containers/storage/libpod DEBU[0000] Using tmp dir /var/run/libpod DEBU[0000] Using volume path /var/lib/containers/storage/volumes DEBU[0000] Set libpod namespace to "" DEBU[0000] [graphdriver] trying provided driver "overlay" DEBU[0000] cached value indicated that overlay is supported DEBU[0000] cached value indicated that metacopy is not being used DEBU[0000] cached value indicated that native-diff is usable DEBU[0000] backingFs=xfs, projectQuotaSupported=false, useNativeDiff=true, usingMetacopy=false DEBU[0000] Initializing event backend journald INFO[0000] Found CNI network podman (type=bridge) at /etc/cni/net.d/87-podman-bridge.conflist ERRO[0000] unable to obtain cgroup stats: open /sys/fs/cgroup/cpuacct/machine.slice/libpod-5dc2040ad82a521dbbbbb65b159dd2b8c4a480ceb6fb91a8096152468c9d84b7.scope/cpuacct.usage_sys: open /sys/fs/cgroup/cpuacct/machine.slice/libpod-5dc2040ad82a521dbbbbb65b159dd2b8c4a480ceb6fb91a8096152468c9d84b7.scope/cpuacct.usage_sys: no such file or directory Test with podman-1.4.4-2.el7.x86_64, seems it works well now.
