This scenario is for scale testing listeners, pools and members.
For each iteration it creates 1 LB and N num_pools and M num_clients
as specified in browbeat-config.yaml. specify the private network
subnet id as vip_subnet_id in browbeat-config which is used by the
LB's. For jump_host_ip specify the floating ip of the jump host.
Prepare user_data.file like below and pass
it to the scenario
PORT=80
NUM_POOLS=2
echo "Running test_server binary"
chmod 777 /home/cirros/test_server.bin
sudo su && echo 1 > /proc/sys/vm/overcommit_memory
for i in $(seq 0 $(($NUM_POOLS-1))); do
./home/cirros/test_server.bin -port $(($PORT+ $i)) &
done
NUM_POOLS per iteration should also be specified in the user_data.file
And in browbeat-config.yml, add absolute path for this user data
file i.e
user_data_file: /home/stack/user_data.file
