If one is doing monitoring or load testing on a live site it is often beneficial to filter out the test browsers from Google Analytics.
When in the Google Analytics Filter section simply Create New Filter, then give it a name, choose the domain name option, and paste in amazonaws.com. That will ensure that our load testing service and monitoring from Washington DC and Dublin, Ireland will get filtered.

For San Francisco, CA monitoring, use the domain gogrid.com.
