# OpenTelemetry Redis Instrumentation

The OpenTelemetry Redis Ruby gem is a community maintained instrumentation for [Redis][redis-home]. This is an in-memory data store that is used as a database, cache, and message broker.

## How do I get started?

Install the gem using:

```
gem install opentelemetry-instrumentation-redis
```

Or, if you use [bundler][bundler-home], include `opentelemetry-instrumentation-redis` in your `Gemfile`.

## Usage

To install the instrumentation, call `use` with the name of the instrumentation.

```ruby
OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::Redis'
end
```

Alternatively, you can also call `use_all` to install all the available instrumentation.

```ruby
OpenTelemetry::SDK.configure do |c|
  c.use_all
end
```

## Example

An example of usage can be seen in [`example/redis.rb`](https://github.com/open-telemetry/opentelemetry-ruby/blob/master/instrumentation/redis/example/redis.rb).

## How can I get involved?

The `opentelemetry-instrumentation-redis` gem source is [on github][repo-github], along with related gems including `opentelemetry-api` and `opentelemetry-sdk`.

The OpenTelemetry Ruby gems are maintained by the OpenTelemetry-Ruby special interest group (SIG).
