Kernel VM Statistics Input Plugin

This plugin gathers virtual memory statistics of the Linux kernel by reading /proc/vmstat. For a full list of available fields check the /proc/vmstat section of the proc man page and for a detailed description about the fields see the vmstat man page.

Introduced in: Telegraf v1.0.0 Tags: system OS support: 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

# Get kernel statistics from /proc/vmstat
# This plugin ONLY supports Linux
[[inputs.kernel_vmstat]]
  # no configuration
