one or more of the policies for an autoscaler: cpuUtilization, customMetricUtilizations,

cpuUtilization to 0.6 or 60%.

coolDownPeriodSec:
|

description:
|
||||
- The number of seconds that the autoscaler should wait before it starts
|
||||
collecting information from a new instance. This prevents the autoscaler
|
||||
from collecting information when the instance is initializing, during
|
||||
which the collected usage would not be reliable. The default time autoscaler
|

waits is 60 seconds.
|

- Virtual machine initialization times might vary because of numerous factors.
|
||||
We recommend that you test how long an instance may take to initialize.
|

To do this, create an instance and time the startup process.

cpuUtilization:

description:

- Defines the CPU utilization policy that allows the autoscaler to scale

description:

- The target CPU utilization that the autoscaler should maintain.
|

- Must be a float value in the range (0, 1]. If not specified, the default
|
||||
is 0.6.
|
||||
- If the CPU level is below the target utilization, the autoscaler scales
|
||||
down the number of instances until it reaches the minimum number of
|
||||
instances you specified or until the average CPU of your instances
|
||||
reaches the target utilization.
|

- If the average CPU is above the target utilization, the autoscaler

scales up until it reaches the maximum number of instances you specified

or until the average utilization reaches the target utilization.

utilizationTarget:
|

description:

- The target value of the metric that autoscaler should maintain. This
|

must be a positive value. A utilization metric scales number of virtual

||||
machines handling requests to increase or decrease proportionally
|

to the metric.
|
||||
- For example, a good metric to use as a utilizationTarget is U(www.googleapis.com/compute/instance/network/received_bytes_count).

- The autoscaler will work to keep this value constant for each of the

instances.
