It shows me some python erros:

Traceback (most recent call last): File "/usr/bin/ulatency", line 1200, in main() File "/usr/bin/ulatency", line 1148, in main tree = Tree(kwargs) File "/usr/bin/ulatency", line 445, in init path = self.get_path() File "/usr/bin/ulatency", line 498, in get_path path = CGROUP_MOUNTS.get(self.tree, None)[0] TypeError: 'NoneType' object has no attribute 'getitem**'

Hi, this seems to be from my fork. I will check this.

gajdusek commented 11 years ago

Please attach output from $ grep cgroup /proc/mounts

You seem not to have cpu cgroup subsystem mounted. Is this intentional?

ulatency-gui tries to list cpu tree when it starts and this is hardcoded. I will add detection of cpu tree available and if not, fallback to other one.

dragonnn commented 11 years ago

No is isn't intentional, I don't know why it isn't mounted, I am using 3.8.4 kernel with ck, uksm and bfq patchset, systemd version is 198-1. This should be useful: └─[22:29 nie,24 mar 13:$]→ zcat /proc/config.gz | grep CGROUP CONFIG_CGROUPS=y /# CONFIG_CGROUP_DEBUG is not set CONFIG_CGROUP_FREEZER=y CONFIG_CGROUP_DEVICE=y /# CONFIG_CGROUP_HUGETLB is not set /# CONFIG_CGROUP_PERF is not set CONFIG_BLK_CGROUP=y /# CONFIG_DEBUG_BLK_CGROUP is not set CONFIG_CGROUP_BFQIO=y CONFIG_NET_CLS_CGROUP=y CONFIG_NETPRIO_CGROUP=m Seems like 3.8.4 kernel don't have CGROUP_CPUACCT config (it is for cpu cgroup I think)?

gajdusek commented 11 years ago

Fixed in ulatency client. I will try to look why cgroup is not mounted on your system later, right now I am constantly disturbing by other duties.

Thanks ;). Fell free to contact me when you have some questions.
