# Trig Input Plugin

This plugin is for demonstration purposes and inserts sine and cosine values
as metrics.

**Introduced in:** Telegraf v0.3.0
**Tags:** testing
**OS support:** all

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

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](/telegraf/v1/configuration/#plugins) for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins

## Configuration

```toml @sample.conf
# Inserts sine and cosine waves for demonstration purposes
[[inputs.trig]]
  ## Set the amplitude
  amplitude = 10.0
```

## Metrics

- trig
  - fields:
    - cosine (float)
    - sine (float)
