datadog-integration

This component is responsible for provisioning Datadog AWS integrations. It depends on the datadog-configuration component to get the Datadog API keys.

See Datadog's documentation about provisioning keys for more information.

Usage

Stack Level: Global

Here's an example snippet for how to use this component. It's suggested to apply this component to all accounts which you want to track AWS metrics with DataDog.

components:
  terraform:
    datadog-integration:

Variables

Required Variables

region (string) required: AWS Region

Optional Variables

account_specific_namespace_rules (map(string)) optional

An object, (in the form {"namespace1":true/false, "namespace2":true/false} ), that enables or disables metric collection for specific AWS namespaces for this AWS account only

Default value: { }

context_host_and_filter_tags (list(string)) optional

Automatically add host and filter tags for these context keys

Default value:

[
  "namespace",
  "tenant",
  "stage"
]

Enable Datadog Cloud Security Posture Management scanning of your AWS account.
See announcement for details.

Default value: null

The AWS account ID Datadog's integration servers use for all integrations

Default value: "464622532012"

excluded_regions (list(string)) optional

An array of AWS regions to exclude from metrics collection

Default value: [ ]

filter_tags (list(string)) optional

An array of EC2 tags (in the form key:value) that defines a filter that Datadog use when collecting metrics from EC2. Wildcards, such as ? (for single characters) and * (for multiple characters) can also be used

Default value: [ ]

host_tags (list(string)) optional

An array of tags (in the form key:value) to add to all hosts and metrics reporting through this integration

Default value: [ ]

included_regions (list(string)) optional

An array of AWS regions to include in metrics collection

Default value: [ ]

integrations (list(string)) optional

List of AWS permission names to apply for different integrations (e.g. 'all', 'core')

Default value:

[
  "all"
]

metrics_collection_enabled (bool) optional

When enabled, a metric-by-metric crawl of the CloudWatch API pulls data and sends it
to Datadog. New metrics are pulled every ten minutes, on average.

Default value: null

resource_collection_enabled (bool) optional

Some Datadog products leverage information about how your AWS resources
(such as S3 Buckets, RDS snapshots, and CloudFront distributions) are configured.
When resource_collection_enabled is true, Datadog collects this information
by making read-only API calls into your AWS account.

Default value: null

Context Variables

The following variables are defined in the context.tf file of this module and part of the terraform-null-label pattern.

additional_tag_map (map(string)) optional

Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id.
This is for some rare cases where resources want additional configuration of tags
and therefore take a list of maps with tag key, value, and additional configuration.

Required: No

Default value: { }

attributes (list(string)) optional

ID element. Additional attributes (e.g. workers or cluster) to add to id,
in the order they appear in the list. New attributes are appended to the
end of the list. The elements of the list are joined by the delimiter
and treated as a single ID element.

Required: No

Default value: [ ]

context (any) optional

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.

Required: No

Default value:

{
  "additional_tag_map": {},
  "attributes": [],
  "delimiter": null,
  "descriptor_formats": {},
  "enabled": true,
  "environment": null,
  "id_length_limit": null,
  "label_key_case": null,
  "label_order": [],
  "label_value_case": null,
  "labels_as_tags": [
    "unset"
  ],
  "name": null,
  "namespace": null,
  "regex_replace_chars": null,
  "stage": null,
  "tags": {},
  "tenant": null
}

delimiter (string) optional

Delimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.

Required: No

Default value: null

descriptor_formats (any) optional

Describe additional descriptors to be output in the descriptors output map.
Map of maps. Keys are names of descriptors. Values are maps of the form
\{<br/> format = string<br/> labels = list(string)<br/> \}
(Type is any so the map values can later be enhanced to provide additional options.)
format is a Terraform format string to be passed to the format() function.
labels is a list of labels, in order, to pass to format() function.
Label values will be normalized before being passed to format() so they will be
identical to how they appear in id.
Default is {} (descriptors output will be empty).

Required: No

Default value: { }

enabled (bool) optional

Set to false to prevent the module from creating any resources
Required: No

Default value: null

environment (string) optional

ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'
Required: No

Default value: null

id_length_limit (number) optional

Limit id to this many characters (minimum 6).
Set to 0 for unlimited length.
Set to null for keep the existing setting, which defaults to 0.
Does not affect id_full.

Required: No

Default value: null

label_key_case (string) optional

Controls the letter case of the tags keys (label names) for tags generated by this module.
Does not affect keys of tags passed in via the tags input.
Possible values: lower, title, upper.
Default value: title.

Required: No

Default value: null

label_order (list(string)) optional

The order in which the labels (ID elements) appear in the id.
Defaults to ["namespace", "environment", "stage", "name", "attributes"].
You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.

Required: No

Default value: null

label_value_case (string) optional

Controls the letter case of ID elements (labels) as included in id,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the tags input.
Possible values: lower, title, upper and none (no transformation).
Set this to title and set delimiter to "" to yield Pascal Case IDs.
Default value: lower.

Required: No

Default value: null

labels_as_tags (set(string)) optional

Set of labels (ID elements) to include as tags in the tags output.
Default is to include all labels.
Tags with empty values will not be included in the tags output.
Set to [] to suppress all generated tags.
Notes:
The value of the name tag, if included, will be the id, not the name.
Unlike other null-label inputs, the initial setting of labels_as_tags cannot be
changed in later chained modules. Attempts to change it will be silently ignored.

Required: No

Default value:

[
  "default"
]

name (string) optional

ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'.
This is the only ID element not also included as a tag.

Required: No

Default value: null

namespace (string) optional

ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique
Required: No

Default value: null

regex_replace_chars (string) optional

Terraform regular expression (regex) string.
Characters matching the regex will be removed from the ID elements.
If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.

Required: No

Default value: null

stage (string) optional

ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'
Required: No

Default value: null

Additional tags (e.g. {'BusinessUnit': 'XYZ'}).
Neither the tag keys nor the tag values will be modified by this module.

Required: No

Default value: { }

tenant (string) optional

ID element (Rarely used, not included by default). A customer identifier, indicating who this instance of a resource is for
Required: No

Default value: null

Outputs
