Hello Dave, I made a new command 'cgget' to help investigating parameters of cgroup. Followings are 2 examples. 1. Print parameters of some cgroup crash> cgget -g cpu / /: cpu.rt_period_us: 1000000 cpu.rt_runtime_us: 950000 cpu.stat: nr_periods: 0 nr_throttled: 0 throttled_time: 0 cpu.cfs_period_us: 0 cpu.cfs_quota_us: 0 cpu.shares: 1024 2. Print parameters of all cgroups crash> cgget -a / /: cpuset.cpu_exclusive: 1 cpuset.mem_exclusive: 1 cpuset.mem_hardwall: 0 cpuset.memory_migrate: 0 cpuset.sched_load_balance: 1 cpuset.memory_spread_page: 0 cpuset.memory_spread_slab: 0 cpuset.memory_pressure_enabled: 0 cpuset.memory_pressure: 0 cpuset.sched_relax_domain_level: -1 cpuset.mems: 0 cpuset.cpus: 0-3 ... blkio.io_merged: 8:0 Read 10925 8:0 Write 31704 8:0 Sync 25413 8:0 Async 17216 8:0 Total 42629 Total 42629 blkio.io_queued: 8:0 Read 0 8:0 Write 0 8:0 Sync 0 8:0 Async 0 8:0 Total 0 Total 0 blkio.reset_stats: To build the module from the top-level crash-<version> directory, enter: $ cp <path-to>/cgget.c extensions $ make extensions Please refer to the attachment for more information. And I'm expecting you to give me some advices soon. -- Zhang Xiaohe Regards -------------------------------------------------- Development Dept.I Nanjing Fujitsu Nanda Software Tech.
