Control Group Input Plugin

This plugin gathers statistics per control group (cgroup).

[!NOTE] Consider restricting paths to the set of cgroups you are interested in if you have a large number of cgroups, to avoid cardinality issues.

The plugin supports the single value format in the form

VAL\n

the new line separated values format in the form

VAL0\n
VAL1\n

the space separated values format in the form

VAL0 VAL1 ...\n

and the space separated keys and value, separated by new line format in the form

KEY0 ... VAL0\n
KEY1 ... VAL1\n

⭐ Telegraf v1.0.0 🏷️ system 💻 linux

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Read specific statistics per cgroup
# This plugin ONLY supports Linux
[[inputs.cgroup]]
  ## Directories in which to look for files, globs are supported.
  ## 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.
  # paths = [
  #   "/sys/fs/cgroup/memory",
  #   "/sys/fs/cgroup/memory/child1",
  #   "/sys/fs/cgroup/memory/child2/*",
  # ]
  ## cgroup stat fields, as file names, globs are supported.
  ## these file names are appended to each path from above.
  # files = ["memory.*usage*", "memory.limit_in_bytes"]

Metrics

All measurements have the path tag.
