# OpenTelemetry lru-memorizer Instrumentation for Node.js

[![NPM Published Version][npm-img]][npm-url]
[![Apache License][license-image]][license-image]

This module provides automatic instrumentation for the [`lru-memorizer`](https://github.com/jfromaniello/lru-memoizer) module, which may be loaded using the [`@opentelemetry/sdk-trace-node`](https://github.com/open-telemetry/opentelemetry-js/tree/main/packages/opentelemetry-sdk-trace-node) package and is included in the [`@opentelemetry/auto-instrumentations-node`](https://www.npmjs.com/package/@opentelemetry/auto-instrumentations-node) bundle.

If total installation size is not constrained, it is recommended to use the [`@opentelemetry/auto-instrumentations-node`](https://www.npmjs.com/package/@opentelemetry/auto-instrumentations-node) bundle with [@opentelemetry/sdk-node](`https://www.npmjs.com/package/@opentelemetry/sdk-node`) for the most seamless instrumentation experience.

Compatible with OpenTelemetry JS API and SDK `1.0+`.

## Installation

```bash
npm install --save @opentelemetry/instrumentation-lru-memoizer
```

## Supported Versions

- `>1.2.0 <3`

## Usage

This instrumentation does not produce any telemetry data. It only bind the caller context to callbacks so downstream operations are recorded with the right context (traceId / parentSpanId / baggadge / etc). This package is a dependency for other popular packages such as [jwks-rsa](https://www.npmjs.com/package/jwks-rsa)

To load a specific plugin, specify it in the registerInstrumentations's configuration:

```js
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { LruMemoizerInstrumentation } = require('@opentelemetry/instrumentation-lru-memoizer');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

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

registerInstrumentations({
  instrumentations: [
    new LruMemoizerInstrumentation(),
  ],
})
```

npm package: @mzahor-test-org/open-telemetry-express
Description: enhanced open telemetry instrumentation for the `express` web framework
Author: Aspecto.io
Latest version: 0.0.37

# `aspecto-open-telemetry-express`

This module provide enhanced instrumentation for the `express` web framework.
The instrumentation conforms to the [Semantic conventions for HTTP spans](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/trace/semantic_conventions/http.md) as well as adding few other attributes:
- Request and Response http payloads (body)
- Request and Response http headers
- Runtime layers executed as part of the request (express `Routers`, `Routes` and middlewares)

## Usage
This plugin is automatically used by `aspecto's` tracing library.

To manually add it to a trace provider:
```
const { NodeTracerProvider } = require('@opentelemetry/node');

const provider = new NodeTracerProvider({
  plugins: {
    express: {
        enabled: true,
        path: '@mzahor-test-org/open-telemetry-express',
    },
  }
});
```
npm package: @mzahor-test-org/open-telemetry-kafka-node

# OpenTelemetry kafka-node Instrumentation for Node.js

This module provides automatic instrumentation for [`kafka-node`](https://github.com/SOHU-Co/kafka-node).

## Installation

```
npm install --save @mzahor-test-org/open-telemetry-kafka-node
```

## Usage

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

const provider = new NodeTracerProvider({
  plugins: {
    'kafka-node': {
      enabled: true,
      // You may use a package name or absolute path to the file.
      path: '@mzahor-test-org/open-telemetry-kafka-node',
    }
  }
});
```

### kafka-node Plugin Options

kafka-node plugin has few options available to choose from. You can set the following:

| Options | Type | Description |
| ------- | ---- | ----------- |
| `producerHook` | `KafkaProducerCustomAttributeFunction` | Hook called before producer message is sent, which allow to add custom attributes to span. |
| `consumerHook` | `KafkaConsumerCustomAttributeFunction` | Hook called before consumer message is processed, which allow to add custom attributes to span. |


## Known Issues
- This library instrument only the `Producer` and `Consumer`.
- Due to the [lack of support](https://github.com/SOHU-Co/kafka-node/issues/1309) in kafka-node in message headers, there is currently no context propagation between producers and consumers.
