Test Autoscaling based on CPU usage

Autoscaling based on a combination of high cpu or throughput is a good way to scale out during periods of heavy use without over-investing in idle capacity.

From the Super-NetOps terminal, generate some traffic to the example app2 application. Replace x.x.x.x with the public IP address of your app2 application.

base64 /dev/urandom | head -c 3000 > payload
ab -t 300 -c 200 -c 5 -T 'multipart/form-data; boundary=1234567890' -p payload https://x.x.x.x/

Apply the cpu_churn iRule to simulate high cpu.
