module: gcp_compute_autoscaler_facts
description:
- Gather facts for GCP Autoscaler
short_description: Gather facts for GCP Autoscaler
version_added: 2.9
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
options:
filters:
description:
- A list of filter value pairs. Available filters are listed here U(https://cloud.google.com/sdk/gcloud/reference/topic/filters).
- Each additional filter in the list will act be added as an AND condition (filter1
and filter2) .
type: list
zone:
description:
- URL of the zone where the instance group resides.
required: true
type: str
extends_documentation_fragment: gcp
'''
EXAMPLES = '''
- name: " a autoscaler facts"
gcp_compute_autoscaler_facts:
zone: us-central1-a
filters:
- name = test_object
project: test_project
auth_kind: serviceaccount
service_account_file: "/tmp/auth.pem"
'''
RETURN = '''
resources:
description: List of resources
returned: always
type: complex
contains:
id:
description:
- Unique identifier for the resource.
returned: success
type: int
creationTimestamp:
description:
- Creation timestamp in RFC3339 text format.
returned: success
type: str
name:
description:
- Name of the resource. The name must be 1-63 characters long and match the
regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character
must be a lowercase letter, and all following characters must be a dash, lowercase
letter, or digit, except the last character, which cannot be a dash.
returned: success
type: str
description:
description:
- An optional description of this resource.
returned: success
type: str
autoscalingPolicy:
description:
- 'The configuration parameters for the autoscaling algorithm. You can define
one or more of the policies for an autoscaler: cpuUtilization, customMetricUtilizations,
and loadBalancingUtilization.'
- If none of these are specified, the default will be to autoscale based on
cpuUtilization to 0.6 or 60%.
returned: success
type: complex
contains:
minNumReplicas:
description:
- The minimum number of replicas that the autoscaler can scale down to.
This cannot be less than 0. If not provided, autoscaler will choose a
default value depending on maximum number of instances allowed.
returned: success
type: int
maxNumReplicas:
description:
- The maximum number of instances that the autoscaler can scale up to. This
is required when creating or updating an autoscaler. The maximum number
of replicas should not be lower than minimal number of replicas.
returned: success
type: int
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.
returned: success
type: int
cpuUtilization:
description:
- Defines the CPU utilization policy that allows the autoscaler to scale
based on the average CPU utilization of a managed instance group.
returned: success
type: complex
contains:
utilizationTarget:
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.
returned: success
type: str
customMetricUtilizations:
description:
- Defines the CPU utilization policy that allows the autoscaler to scale
based on the average CPU utilization of a managed instance group.
returned: success
type: complex
contains:
metric:
description:
- The identifier (type) of the Stackdriver Monitoring metric.
- The metric cannot have negative values.
- The metric must have a value type of INT64 or DOUBLE.
returned: success
type: str
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.
returned: success
type: str
utilizationTargetType:
description:
- Defines how target utilization value is expressed for a Stackdriver
Monitoring metric. Either GAUGE, DELTA_PER_SECOND, or DELTA_PER_MINUTE.
returned: success
type: str
loadBalancingUtilization:
description:
- Configuration parameters of autoscaling based on a load balancer.
returned: success
type: complex
contains:
utilizationTarget:
description:
- Fraction of backend capacity utilization (set in HTTP(s) load balancing
configuration) that autoscaler should maintain. Must be a positive
float value. If not defined, the default is 0.8.
returned: success
type: str
target:
description:
- URL of the managed instance group that this autoscaler will scale.
returned: success
type: dict
zone:
description:
- URL of the zone where the instance group resides.
returned: success
type: str
