CGroup Input Plugin

This input plugin will capture specific statistics per cgroup.

Consider restricting paths to the set of cgroups you really want to monitor if you have a large number of cgroups, to avoid any cardinality issues.

Following file formats are supported:

  • Single value
VAL\n
  • New line separated values
VAL0\n
VAL1\n
  • Space separated values
VAL0 VAL1 ...\n
  • New line separated key-space-value's
KEY0 VAL0\n
KEY1 VAL1\n

Tags:

All measurements have the following tags:

  • path

Configuration:

# [[inputs.cgroup]]
  # paths = [
  #   "/sys/fs/cgroup/memory",           # root cgroup
  #   "/sys/fs/cgroup/memory/child1",    # container cgroup
  #   "/sys/fs/cgroup/memory/child2/*",  # all children cgroups under child2, but not child2 itself
  # ]
  # files = ["memory.*usage*", "memory.limit_in_bytes"]

usage examples:

# [[inputs.cgroup]]
  # paths = [
  #   "/sys/fs/cgroup/cpu",              # root cgroup
  #   "/sys/fs/cgroup/cpu/*",            # all container cgroups
  #   "/sys/fs/cgroup/cpu/*/*",          # all children cgroups under each container cgroup
  # ]
  # files = ["cpuacct.usage", "cpu.cfs_period_us", "cpu.cfs_quota_us"]

# [[inputs.cgroup]]
  # paths = [
  #   "/sys/fs/cgroup/unified/*",        # root cgroup
  # ]
  # files = ["*"]
