The [New Relic Ruby agent](https://docs.newrelic.com/docs/agents/ruby-agent/getting-started/new-relic-ruby) automatically instruments the Redis gem (gem version 3.0.0 or higher). After you [install the agent](https://docs.newrelic.com/docs/agents/ruby-agent/installation-configuration/ruby-agent-installation) and generate traffic for your app, you can view Redis operations on the [APM **Summary** page](https://docs.newrelic.com/docs/apm/applications-menu/monitoring/apm-overview-page), on the [**Databases** page](https://docs.newrelic.com/docs/apm/applications-menu/monitoring/databases-slow-queries-page), and in [transaction traces](https://docs.newrelic.com/docs/apm/transactions/transaction-traces/transaction-traces). For example, the main chart on the APM **Summary** page will show color-coded Redis information.

> #### 💡 TIP
>
> Redis instrumentation requires Ruby agent version 3.13.0 or higher.

## Interaction with newrelic-redis [#third-party-gems]

The third-party `newrelic-redis` gem provides Redis instrumentation support as an add-on to New Relic's Ruby agent. If the Ruby agent detects `newrelic-redis`, it will not install the built-in Redis instrumentation and will record a log message like this at startup:

```log
INFO : Not installing New Relic supported Redis instrumentation because the third party newrelic-redis gem is present
```

To use New Relic's built-in Redis instrumentation and view Redis information in the UI, remove the `newrelic-redis` gem.

> #### ⚠️ IMPORTANT
>
> Removing the `newrelic-redis` gem in favor of the built-in instrumentation will change your transaction names. To preserve your existing transaction names, ignore the log message and do not uninstall the gem.

## Capture Redis command arguments [#ex_sidekiq_args]

By default, the Ruby agent only captures Redis command names. To capture Redis command arguments, use this configuration:

```yml
transaction_tracer:
  record_redis_arguments: true
```

The agent limits the number of characters and arguments collected from each transaction trace node. The agent truncates items that exceed these limits.
