Cron scripts that report metric data to Amazon CloudWatch

These scripts are meant to be run by cron on ec2 servers every 5 minutes.

Use the varnish-aws-logger.py to report varnishstat data to Amazon. Rolls into the 'Varnish' namespace and associates the metrics with the instance id of the machine it's run on.

Look at the settings.py file to configure what metrics you want sent to AWS.

Use the nginx-aws-logger.py to report nginx status data to Amazon. Rolls into the 'Nginx' namespace and associates the metrics with the instance id of the machine it's run on.

You have to make sure you have the following in your nginx config:

server {
	listen 127.0.0.1:8000;

	location /nginx_status {
		# copied from http://blog.kovyrin.net/2006/04/29/monitoring-nginx-with-rrdtool/
		stub_status on;
		access_log   off;
		allow 127.0.0.1;
		deny all;
	}
}
