Cadvisor: how can i get the "container_fs_io_current"? why is always 0

[TwitchChen]

why the 'fs_stats' of cAdvisor's /metrics is always 0,like this:

[barnettZQG]

I also got the info about io is always 0 from cadvisor and prometheus.

[barnettZQG]

Can you explain what time can solve this issue? thank you

[skebo]

yes, all my blkio stats for containers are all 0 as well. I've tested on ubuntu 16.04 (docker v1.6 through 1.12 w/aufs) and RHEL 7.2 (docker 1.11 and 1.12 w/devicemapper) with my I/O scheduler set to cfq and I still get all zeroes.

Here is the /validate from my ubuntu box:

cAdvisor version: 0.23.8

OS version: Alpine Linux v3.2

Kernel version: [Supported and recommended]
    Kernel version is 4.4.0-34-generic. Versions >= 2.6 are supported. 3.0+ are recommended.


Cgroup setup: [Supported and recommended]
    Available cgroups: map[freezer:1 net_cls:1 perf_event:1 hugetlb:1 pids:1 cpuset:1 cpuacct:1 memory:1 devices:1 net_prio:1 cpu:1 blkio:1]
    Following cgroups are required: [cpu cpuacct]
    Following other cgroups are recommended: [memory blkio cpuset devices freezer]
    Hierarchical memory accounting enabled. Reported memory usage includes memory used by child containers.


Cgroup mount setup: [Supported and recommended]
    Cgroups are mounted at /sys/fs/cgroup.
    Cgroup mount directories: blkio cpu cpu,cpuacct cpuacct cpuset devices freezer hugetlb memory net_cls net_cls,net_prio net_prio perf_event pids systemd 
    Any cgroup mount point that is detectible and accessible is supported. /sys/fs/cgroup is recommended as a standard location.
    Cgroup mounts:

@skebo
you could use docker api about cgroup.it could get blkio stats

[renatosis]

Hi @skebo , did u solve this issue? how?

Thanks

[skebo]

no @renatosis, i did not solve this problem and didn't see any progress, so we've moved away from cadvisor.

[k-s-dean]

@skebo Out of interest what did you move to ? I am surprised that none of the cadvisor maintainers or developers are willing to let us know why 0 is being returned.

[skebo]

@k-s-dean we moved to Datadog. I'd really prefer a non-commercial solution, so I was also very disappointed by the flaw. However, the lack of response on this issue was really what sealed the deal. There was no indication that this problem would ever be addressed.
