[Serverless monitoring for AWS Lambda](https://docs.newrelic.com/docs/introduction-new-relic-monitoring-aws-lambda) offers in-depth performance monitoring for your Lambda functions. This document explains how to:

-   [Find your Lambda data in the UI](#find-data)
-   [Understand the UI components](#ui-pages)
-   [Understand your chart data](#chart-data)
-   [How to create custom charts](#chart-data)

## View your data [#find-data]

**[one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > All entities > Amazon Web Services > Lambda functions**: Click Lambda functions to see charts and details.

To view your Lambda data in New Relic: Go to **[one.newrelic.com](https://one.newrelic.com/all-capabilities)**, click **Explorer.** In the left nav under **Amazon Web Services**, click **Lambda functions.**

For more about our UI, see [Intro to the New Relic platform](https://docs.newrelic.com/docs/project-wanda-early-access-future-new-relic-platform).

> #### ⚠️ IMPORTANT
>
> If you can't find your Lambda data:
>
> -   Ensure you've followed the [instructions for enabling Lambda monitoring](https://docs.newrelic.com/docs/install-enable-new-relics-monitoring-aws-lambda).
> -   Note that this feature is different from our [infrastructure monitoring Lambda integration](https://docs.newrelic.com/docs/integrations/amazon-integrations/aws-integrations-list/aws-lambda-monitoring-integration).

## UI pages

Here are descriptions of the UI pages available for our Lambda monitoring:

| UI page             | Functionality                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Summary             | The **Summary** page displays charts that give you a quick view into the most important performance data. If available, this will feature data gathered from [APM agent instrumentation](https://docs.newrelic.com/docs/serverless-function-monitoring/aws-lambda-monitoring/get-started/enable-new-relic-monitoring-aws-lambda#instrument-lambda). Lambda functions instrumented via OpenTelemetry (ADOT layer) now display the same Summary page experience as APM-instrumented Lambda functions, with metrics normalized to the `apm.*` format via a metric synthesis layer. |
| CloudWatch metrics  | The **CloudWatch metrics** tab displays Lambda performance data sourced from AWS CloudWatch via New Relic's metric synthesis layer. Charts include: invocation counts, duration, throttles, and error counts. This tab is available for both APM-instrumented and OpenTelemetry (ADOT)-instrumented Lambda functions.                                                                                                                                                                                                                                                           |
| Transactions        | The **Transactions** tab lists Lambda transactions along with performance data such as duration and throughput. The **AWS Request ID** column identifies each Lambda execution by its unique AWS request identifier, allowing you to drill down into a specific invocation's APM transaction trace.                                                                                                                                                                                                                                                                             |
| Distributed tracing | The **Distributed tracing** page shows distributed traces that include the monitored Lambda function. For details about this feature, see [Distributed tracing](https://docs.newrelic.com/docs/apm/distributed-tracing/getting-started/introduction-distributed-tracing).                                                                                                                                                                                                                                                                                                       |
| Errors              | The **Errors** page displays errors (`AwsLambdaInvocationError` events). You can filter by error rate, error percentage, or error class. You can drill down into errors and see [attributes](https://docs.newrelic.com/docs/using-new-relic/welcome-new-relic/getting-started/glossary#attribute) and, if available, stack traces.                                                                                                                                                                                                                                              |
| Logs                | The **Logs** page displays recent log messages from your Lambda function. For details about this feature, see [Logs](https://docs.newrelic.com/docs/logs/new-relic-logs/get-started/introduction-new-relic-logs).                                                                                                                                                                                                                                                                                                                                                               |

## Understand chart data [#chart-data]

Lambda data charts are generated by running [NRQL queries](https://docs.newrelic.com/docs/insights/nrql-new-relic-query-language/using-nrql/introduction-nrql) of Lambda-related [event data](https://docs.newrelic.com/docs/understand-your-lambda-data#data-structure). You might view a chart's NRQL query to:

-   To better understand what a chart is displaying
-   To get ideas on how to create a custom NRQL query and chart
