> #### ⚠️ IMPORTANT
>
> Enable the [AWS CloudWatch Metric Streams integration](https://docs.newrelic.com/docs/infrastructure/amazon-integrations/aws-integrations-list/aws-metric-stream/) to monitor all CloudWatch metrics from your AWS services, including custom namespaces. Individual integrations are no longer our recommended option.

New Relic offers an integration for reporting your [Amazon Quantum Ledger Database (QLDB)](https://aws.amazon.com/qldb/) data to New Relic. This document explains how to activate this integration and describes the data that can be reported.

## Activate integration [#activate]

To enable this integration follow standard procedures to [Connect AWS services to New Relic](https://docs.newrelic.com/docs/infrastructure/infrastructure-integrations/getting-started/connect-aws-integrations-infrastructure).

## Configuration and polling [#polling]

You can change the polling frequency and filter data using [configuration options](https://docs.newrelic.com/docs/integrations/new-relic-integrations/getting-started/configure-polling-frequency-data-collection-cloud-integrations).

Default [polling](https://docs.newrelic.com/docs/infrastructure/amazon-integrations/aws-integrations-list/aws-polling-intervals-infrastructure-integrations) information for the Amazon QLDB integration:

-   New Relic polling interval: 5 minutes
-   Amazon CloudWatch data interval: 1 minute

## Find and use data [#find-data]

To find your integration data, go to **[one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > Infrastructure > AWS** and select an integration.

Data from this integration is attached to the following [event type](https://docs.newrelic.com/docs/data-apis/understand-data/new-relic-data-types/#event-data):

| Entity | Event Type            | Provider        |
| ------ | --------------------- | --------------- |
| Ledger | `AwsQldbLedgerSample` | `AwsQldbLedger` |

For more on how to use your data, see [Understand and use integration data](https://docs.newrelic.com/docs/infrastructure/integrations/find-use-infrastructure-integration-data).

## Metric data [#metrics]

This integration collects Amazon QLDB data for Ledger.

### QLDB Ledger data

| Metric                          | Unit         | Description                                                                                                                                                                                                        |

| `journalStorage`                | Bytes        | The total amount of disk space used by the ledger's journal, reported in 15-minute intervals. The journal contains the complete, immutable, and verifiable history of all the changes to your data.                |
| `indexedStorage`                | Bytes        | The total amount of disk space used by the ledger's tables, indexes, and indexed history, reported in 15-minute intervals. Indexed storage consists of ledger data that is optimized for high-performance queries. |
| `readIOs`                       | Count        | The number of disk read I/O operations, reported in one-minute intervals.                                                                                                                                          |
