This plugin sends telegraf metrics to an external application over stdin.
The command should be defined similar to docker's exec form:
["executable", "param1", "param2"]
On non-zero exit stderr will be logged at error level.
For better performance, consider execd, which runs continuously.
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.
