Extracting Metadata from Load Generator Instances

RedLine13 load generator instances are backed by AWS EC2 instances. AWS exposes a special locally-addressable endpoint that returns metadata about that instance. Using this, you can ascertain such things as the region in which your instance resides, private and public addresses, and instance tags amongst other useful data points. A specific example of where this would be useful is where you have defined a load test to run in multiple regions, with a number of EC2-backedRead More →
