This directory contains tools to generate large services to test Istio under heavy load.
Service Graph provides a large tree of 20 services that will call each other, generated by isotope:
It will also set up an instance of Fortio to generate load.
To setup a service graph, run ./setup_large_test.sh NUM, where num is the number of instances to run.
Each instance will be created in a namespace service-graph##.
Each instance requests roughly 6 vCPUs and 6Gi of memory with Istio defaults.
