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.
⭐ 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.
