You can send your CloudWatch logs to New Relic using our AWS Lambda function,
newrelic-log-ingestion, which can be easily deployed from the AWS Serverless application repository.
To use our CloudWatch logs Lambda function, you only need a New Relic license key.
Install the Cloudwatch logs Lambda function
Configure your Lambda function
You can configure logs forwarding using the following environment variables:
||New Relic License key, needed for sending data to New Relic Infrastructure and Logs. If set, it enables forwarding to New Relic Infrastructure by default. Required.||Your New Relic license key.|
||Determines if logs are forwarded to New Relic. Required.||Default:
||Determines if logs are forwarded to New Relic Infrastructure. Required.||Default:
||New Relic ingestion endpoint for Logs. Optional.||US:
||New Relic ingestion endpoint for Infrastructure. Optional.||
- Once you have updated the
function.pyand added the environment variables, click Save. Once complete, link your Lambda function to CloudWatch Logs.
Create a Lambda trigger
To get your logs streaming to New Relic you will need to attach a trigger to the Lambda:
- From the left side menu, select Functions.
- Find and select the previously created
- Under Designer, click Add Triggers, and select Cloudwatch Logs from the dropdown.
- Select the the appropriate Log group for your application.
- Enter a name for your filter.
- Optional: Enter a filter pattern.
- Check the Enable trigger checkbox, then click Add to create the trigger.
Configure retries (optional)
You can configure the number of retries you want to perform in case the function fails to send the data in case of communication issues. Recommended number is 3 retries, but you can change the retry behavior by changing the below parameters:
Be aware that more number of retries can make the function run for longer time and therefore increases the probability of having higher costs for Lambda. On the contrary, decreasing the number of retries could increase the probability of data loss.
MAX_RETRIES = 3 # Defines the number of retries after lambda failure to deliver data INITIAL_BACKOFF = 1 # Defines the initial wait seconds until next retry is executed BACKOFF_MULTIPLIER = 2 # Time multiplier between the retries As an example, in default above configuration, first retry will happen after 1 second, second retry after 2 seconds and third retry will happen after 4 seconds.
Resources created by the SAM template
There are few resources that will be created when you create the application from the repository:
- The Lambda function itself
- A Role used to give execution permissions to the Lambda function based in CloudWatch Logs.
All other lambda configurations not listed in the steps above can be left as the defaults.
View log data
If everything is configured correctly and your data is being collected, you should see data logs in both of these places:
- New Relic Logs UI
- New Relic tools for running NRQL queries. For example, you can execute a query like this:
SELECT * FROM Log
Now that you've enabled Logs, here are some potential next steps:
- Explore your data using the Logs UI.
- Configure your agent to see contextual log data, such as distributed tracing, stack traces, application logs, and more.
- Query your data and create custom dashboards or alerts.
If no data appears after you enable log management, follow the troubleshooting procedures.
