Control Group Input Plugin
This plugin gathers statistics per control group (cgroup).
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\nthe new line separated values format in the form
VAL0\n
VAL1\nthe space separated values format in the form
VAL0 VAL1 ...\nand the space separated keys and value, separated by new line format in the form
KEY0 ... VAL0\n
KEY1 ... VAL1\nIntroduced in: Telegraf v1.0.0 Tags: system OS support: linux

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.
