This module provides automatic instrumentation for [`redis@^2.6.0`](https://github.com/NodeRedis/node_redis).

For automatic instrumentation see the
[@opentelemetry/node](https://github.com/open-telemetry/opentelemetry-js/tree/main/packages/opentelemetry-node) package.

## Installation

```
npm install --save @opentelemetry/plugin-redis
```

### Supported Versions
 - `>=2.6.0`

## Usage

OpenTelemetry Redis Instrumentation allows the user to automatically collect trace data and export them to the backend of choice, to give observability to distributed systems when working with [redis](https://www.npmjs.com/package/redis).

To load a specific plugin (**redis** in this case), specify it in the registerInstrumentations's configuration
```js
const { NodeTracerProvider } = require('@opentelemetry/node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();
provider.register();

registerInstrumentations({
  instrumentations: [
    {
      plugins: {
        redis: {
          enabled: true,
          // You may use a package name or absolute path to the file.
          path: '@opentelemetry/plugin-redis',
        }
      },
    },
  ],
  tracerProvider: provider,
});
```

To load all of the [supported plugins](https://github.com/open-telemetry/opentelemetry-js#plugins), use below approach. Each plugin is only loaded when the module that it patches is loaded; in other words, there is no computational overhead for listing plugins for unused modules.
```javascript
const { NodeTracerProvider } = require('@opentelemetry/node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();
provider.register();
registerInstrumentations({
  tracerProvider: provider,
});
```

See [examples/redis](https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/examples/redis) for a short example.
