If you're deploying parse-server onto an AWS cluster (either ecs, straight ec2, or elastic beanstalk). It is useful to see all of the machines logs all in one place. AWS Firehose will accept logging at any scale. With just a few clicks on the AWS console, you can setup a firehose stream that feeds into elastic search. AWS provides a link to a kibana ui to elastic search that makes visualizing your logs nice and easy.
loggerAdapter: new FirehoseLoggerAdapter({ streamName });
Other winston logger options can also be passed:
loggerAdapter: new FirehoseLoggerAdapter({ streamName, level: 'verbose' });
It should be possible to pass accessKeyId and secretAccessKey values in the options.
For AWS credentials, see Configuring the SDK for JavaScript. On developer machines, use a standard location for your credentials. For deployment on EC2, use a role.
