Instance Attribute Summary

• #alarms ⇒ Array<String>

  Custom CloudWatch auto scaling alarms, to be used as thresholds.

• #cpu_threshold ⇒ Float

  The CPU utilization threshold, as a percent of the available CPU.

• #ignore_metrics_time ⇒ Integer

  The amount of time (in minutes) after a scaling event occurs that OpsWorks Stacks should ignore metrics and suppress additional scaling events.

• #instance_count ⇒ Integer

  The number of instances to add or remove when the load exceeds a threshold.

• #load_threshold ⇒ Float

  The load threshold.

• #memory_threshold ⇒ Float

  The memory utilization threshold, as a percent of the available memory.

• #thresholds_wait_time ⇒ Integer

  The amount of time, in minutes, that the load must exceed a threshold before more instances are added or removed.

Instance Attribute Details

#alarms ⇒ Array<String>

Custom CloudWatch auto scaling alarms, to be used as thresholds. This parameter takes a list of up to five alarm names, which are case sensitive and must be in the same region as the stack.

<note markdown=“1”> To use custom alarms, you must update your service role to allow ‘cloudwatch:DescribeAlarms`. You can either have OpsWorks Stacks update the role for you when you first use this feature or you can edit the role manually. For more information, see [Allowing OpsWorks Stacks to Act on Your Behalf].

  include Aws::Structure
end

#ignore_metrics_time ⇒ Integer

The amount of time (in minutes) after a scaling event occurs that OpsWorks Stacks should ignore metrics and suppress additional scaling events. For example, OpsWorks Stacks adds new instances following an upscaling event but the instances won’t start reducing the load until they have been booted and configured. There is no point in raising additional scaling events during that operation, which typically takes several minutes. ‘IgnoreMetricsTime` allows you to direct OpsWorks Stacks to suppress scaling events long enough to get the new instances online.
