Sometimes errors get missed during development, but when they're on production they're more likely to be triggered because of the number of people accessing different parts of the site. I find it really helpful to have errors on live yell at me — it's a little unnerving to have error logs buried in the server where I'm unlikely to access them on an everyday basis.

Though really is kind of a sad thing where we find out if we broke something when the errors start getting triggered… just another case for more unit tests…

Setting up CloudWatch log agent: http://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/QuickStartEC2Instance.html

This was the output after running through the Interactive config:

------------------------------------------------------
- Configuration file successfully saved at: /var/awslogs/etc/awslogs.conf
- You can begin accessing new log events after a few moments at https://console.aws.amazon.com/cloudwatch/home?region=us-east-1#logs:
- You can use 'sudo service awslogs start|stop|status|restart' to control the daemon.
- To see diagnostic information for the CloudWatch Logs Agent, see /var/log/awslogs.log
- You can rerun interactive setup using 'sudo python ./awslogs-agent-setup.py --region us-east-1 --only-generate-config'
