Amazon RDS Enhanced Monitoring integration

New Relic infrastructure integrations include an integration for collecting enhanced Amazon RDS data; this supplements the basic New Relic RDS integration with real-time metrics about the operating system the database instance runs on.

Features

This New Relic integration allows you to monitor and alert on RDS Enhanced Monitoring. You can use integration data and to monitor the DB processes and identify potential trouble spots as well as to profile the DB allowing you to improve and optimize their response and cost.

Enable enhanced monitoring

Importante

Enabling this integration will incur some additional charges to your Amazon CloudWatch account. In addition there are some limitations and CPU metric data collection differences that are explained in Amazon's enhanced monitoring documentation.

You must first have the New Relic Amazon RDS monitoring integration enabled before enabling RDS Enhanced Monitoring. Be sure that you have completed the steps in Connect AWS services to New Relic.

New Relic uses AWS Lambda in order to collect RDS logs and provide near-real time data of your RDS instances, this capability is called RDS Enhanced Monitoring in AWS.

Follow these steps to enable RDS Enhanced Monitoring integration:

Specify the RDS instances that need Enable RDS Enhanced Monitoring. You can specify this when creating or modifying the instance: under Monitoring, set Enable Enhanced Monitoring to Yes. We recommend setting the data Granularity to 15 seconds.
After enhanced monitoring is enabled, a stream called RDSOSMetrics is created in AWS CloudWatch Logs. Enhanced monitoring metrics are available via this stream. Create a lambda function and subscribe it to that stream in the following steps to obtain the data.
Create a new AWS Lambda function from the Serverless Repository: Go to Lambda > Create Function > Browse serverless App repository, check the box for Show apps that create custom IAM roles or resource policies, and search for NewRelic-log-ingestion.
Populate the LICENSE_KEY environment variable with your New Relic account .
Review all optional parameters and adapt them based on your use cases.
Select Deploy to create a new CloudFormation stack, a new function called newrelic-log-ingestion, and the required role.
Go to the newrelic-log-ingestion function.
Continue with the procedure to stream logs to the Lambda function.

Sugerencia

The newrelic-log-ingestion function requires the AWSLambdaBasicExecutionRole policy which contains the minimum permissions (as recommended by AWS). A custom IAM role name can be defined at install time, otherwise, an appropriate Role will be created, which will require CAPABILITY_IAM to be acknowledged.

Stream logs to Lambda function

To link the RDSOSMetrics log stream to the Lambda function (JSON format):

From AWS Console > CloudWatch > Logs, select RDSOSMetrics log group, and apply Actions > Create Lambda subscription filter.
For the Lambda function, select newrelic-log-ingestion.
From the Log Format dropdown, select JSON as the Log format.
Enter a Subscription filter name.
At the bottom, click the Start streaming button to save your Lambda subscription filter.

Once completed, the Lambda function will send all the log lines from RDSOSMetrics to New Relic's ingest services.

Configuration and polling

You can change the polling frequency and filter data using configuration options.

Default polling information for the Amazon RDS Enhanced Monitoring integration:

New Relic polling interval:
- 30 seconds on average (collected via CloudWatch Logs)
- Configurable when setting up AWS Lambda
Amazon CloudWatch data interval: 1 minute

Find and use data

To find your integration data, go to one.newrelic.com > All capabilities > Infrastructure > AWS and select the RDS > Enhanced monitoring dashboard link.

You can query and explore your data using the DatastoreSample event type, with a provider value of RdsDbInstance .
