A grid is a group of flood agents running on any type of computer (for example a laptop or a cloud-managed VM instance).
If you're working on a single machine (your laptop for example) you can let
flood-agent pick a random name like
Say you'd like to run a larger grid. You could run
flood-agent on a second machine
flood-agent --grid submerged-dolphin
However, in this case it'd just be easier to start both agents with a grid name of your choosing:
# ec2 instance 1aws-ec2-1 $ ./flood-agent --name aws-grid-1# ec2 instance 2aws-ec2-2 $ ./flood-agent --name aws-grid-1
For example, using a laptop on home a broadband connection and an extra-large VM instance located in a cloud provider's datacenter as part of the same grid would make test results difficult to interpret and trust.
A flood is an instance of a load test plan. To run a load test, a flood is scheduled onto one or more grids.
So, when you run a flood, it ends up running on all the
flood-agent instances running within the grids you have organised and selected:
