A set of test scripts for testing Gorouter upgrade performance when upgrades are occurring. Can be used generally, but were originally intended for testing Cloud Foundry's Multiple Certificate feature:
https://docs.cloudfoundry.org/adminguide/securing-traffic.html#multcerts
test-routers.sh
https://github.com/bendalby82/sniboshtest/blob/master/test-routers.sh
This script will continually poll your Gorouters. Should run from a VM that is on the same network as the Gorouters, so that traffic does not go through your load balancer.
test-lb.sh
https://github.com/bendalby82/sniboshtest/blob/master/test-lb.sh
This script will continually poll your load balancer. Can be run from anywhere with access to your foundation.
test-lb-verbose.sh
https://github.com/bendalby82/sniboshtest/blob/master/test-lb-verbose.sh
Verbose version of the test-lb.sh script - useful if you detect problems with test-lb.sh, and want to see all the details.
Note the use of the --max-time switch with the curl command - make sure you don't set this too low, or delays will be interpreted as failures.
