class Aws::OpsWorks::Types::AutoScalingThresholds

Describes a load-based auto scaling upscaling or downscaling threshold configuration, which specifies when AWS OpsWorks Stacks starts or stops load-based instances.

@note When making an API call, you may pass AutoScalingThresholds

data as a hash:

    {
      instance_count: 1,
      thresholds_wait_time: 1,
      ignore_metrics_time: 1,
      cpu_threshold: 1.0,
      memory_threshold: 1.0,
      load_threshold: 1.0,
      alarms: ["String"],
    }

@!attribute [rw] instance_count

The number of instances to add or remove when the load exceeds a
threshold.
@return [Integer]

@!attribute [rw] thresholds_wait_time

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

@!attribute [rw] ignore_metrics_time

The amount of time (in minutes) after a scaling event occurs that
AWS OpsWorks Stacks should ignore metrics and suppress additional
scaling events. For example, AWS 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 AWS OpsWorks Stacks to suppress scaling events long
enough to get the new instances online.
@return [Integer]

@!attribute [rw] cpu_threshold

The CPU utilization threshold, as a percent of the available CPU. A
value of -1 disables the threshold.
@return [Float]

@!attribute [rw] memory_threshold

The memory utilization threshold, as a percent of the available
memory. A value of -1 disables the threshold.
@return [Float]

@!attribute [rw] load_threshold

The load threshold. A value of -1 disables the threshold. For more
information about how load is computed, see [Load (computing)][1].

@return [Float]

@!attribute [rw] alarms

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 AWS 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 AWS
OpsWorks Stacks to Act on Your Behalf][1].
