Use of blkio stats


(Paolovalente) #1

Hi,
I have a technical question. Could you please tell me whether blkio statistics for the proportional share policy are used in some way in Docker? I’m referring to the content of the following special files in, e.g., /sys/fs/cgroup/blkio:
blkio.io_merged
blkio.io_merged_recursive
blkio.io_queued
blkio.io_queued_recursive
blkio.io_service_bytes
blkio.io_service_bytes_recursive
blkio.io_serviced
blkio.io_serviced_recursive
blkio.io_service_time
blkio.io_service_time_recursive
blkio.io_wait_time
blkio.io_wait_time_recursive

If this is not the right forum to ask this question, could you please point me to the right one?

Thanks,
Paolo
