Create an Agent Configuration File

The following example shows how to create an agent configuration file on the Amazon EC2 instance using Nano:

$ nano /tmp/cwlogs/application.conf

Add the following to the configuration file:

[general] state_file = /var/awslogs/agent-state [application.log] file = /home/ec2-user/DataExport/logs/application.log* log_group_name = MobileAnalytics.application.log log_stream_name = {instance_id}/application.log datetime_format = %a %b %d %H:%M:%S %Y

Start the CloudWatch Agent

$ sudo python / -n -r us-east-1 -c /tmp/cwlogs/application.conf
