Description Gan Huang 2017-06-07 11:49:01 EDT
Description of problem:
Creating a heat stack with autoscaling enabled ("autoscaling: true"), it turned out that the stack was not able to scale up automatically.

Version-Release number of selected component (if applicable):
OCP 3.4 on OSP 10

How reproducible:

Steps to Reproduce:
1. Create a heat stack using following parameters template:


2. After stack complete, adding CPU load against the app node.
for i in `seq 1 $(cat /proc/cpuinfo |grep "physical id" |wc -l)`; do dd if=/dev/zero of=/dev/null & done

Actual results:
The stack has no actions with the CPU load, the app node are not scaled up as expected.

Expected results:
The app node should be scaled up as expected once the CPU of app node reached the defined CPU threshold.
