Assigning this to kernel as looking most relevant.
('iotop' itself has no specific maintainer).Summary:
error showing SWAPIN and IO % data in iotop =>
error showing SWAPIN and IO % data in 'iotop': CONFIG_TASK_DELAY_ACCT not enabled in kernel It was changed in Kernel last year for a reason: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e4042ad492357fa995921376462b04a025dd53b6 Workaround described here: https://superuser.com/questions/610581/iotop-complains-config-task-delay-acct-not-enabled-in-kernel-only-for-specific Adding "delayacct" to grub command line Yep. the kernel parameter is needed if you want the feature Status:
NEW =>
RESOLVED thank you for your help, i will try the workaround |
