This module creates the resources and automates ingestion of ECS Application Autoscaling events to the cloud watch log.

And creates a CloudWatch log insight query to generate statistics on the scaling events.

Usage

module "application-autoscaling-activities" {
  source       = "terraform-aws-application-autoscaling-activities"
  cluster_arn  = "XXXX"
  cluster_name = "XXXX"
}

Inputs

Name	Description	Type	Default	Required
additional_tag_map	Additional tags for appending to tags_as_list_of_maps. Not added to tags.	map(string)	{}	no
attributes	Additional attributes (e.g. 1)	list(string)	[]	no
aws_region	Provide the aws region	string	"us-west-2"	no
context	Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as null to use default value. Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged.	any	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {} }	no
delimiter	Delimiter to be used between namespace, environment, stage, name and attributes. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
ecs_cluster_arn	Provide the ECS cluster ARN	string	n/a	yes
enabled	Set to false to prevent the module from creating any resources	bool	null	no
environment	Environment, e.g. 'uw2', 'us-west-2', OR 'prod', 'staging', 'dev', 'UAT'	string	null	no
id_length_limit	Limit id to this many characters (minimum 6). Set to 0 for unlimited length. Set to null for default, which is 0. Does not affect id_full.	number	null	no
label_key_case	The letter case of label keys (tag names) (i.e. name, namespace, environment, stage, attributes) to use in tags. Possible values: lower, title, upper. Default value: title.	string	null	no
label_order	The naming order of the id output and Name tag. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 5 elements, but at least one must be present.	list(string)	null	no
label_value_case	The letter case of output label values (also used in tags and id). Possible values: lower, title, upper and none (no transformation). Default value: lower.	string	null	no
