Synopsis

  • Gather info for GCP Metric

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.6

  • requests >= 2.18.4

Parameters

Parameter

Comments

auth_kind

string / required

The type of credential used.

Choices:

  • "application"

  • "machineaccount"

  • "serviceaccount"

env_type

string

Specifies which Ansible environment you’re running this module within.

This should not be set unless you know what you’re doing.

This only alters the User Agent string for any API requests.

project

string

The Google Cloud Platform project to use.

scopes

list / elements=string

Array of scopes to be used

service_account_contents

jsonarg

The contents of a Service Account JSON file, either in a dictionary or as a JSON string that represents it.

service_account_email

string

An optional service account email address if machineaccount is selected and the user does not wish to use the default email.

service_account_file

path

The path of a Service Account JSON file if serviceaccount is selected as type.

Notes

Note

  • for authentication, you can set service_account_file using the gcp_service_account_file env variable.

  • for authentication, you can set service_account_contents using the GCP_SERVICE_ACCOUNT_CONTENTS env variable.

  • For authentication, you can set service_account_email using the GCP_SERVICE_ACCOUNT_EMAIL env variable.

  • For authentication, you can set auth_kind using the GCP_AUTH_KIND env variable.

  • For authentication, you can set scopes using the GCP_SCOPES env variable.

  • Environment variables values will only be used if the playbook values are not set.

  • The service_account_email and service_account_file options are mutually exclusive.

Examples

- name: get info on a metric
  gcp_logging_metric_info:
    project: test_project
    auth_kind: serviceaccount
    service_account_file: "/tmp/auth.pem"

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key

Description

resources

complex

List of resources

Returned: always

bucketOptions

complex

The bucketOptions are required when the logs-based metric is using a DISTRIBUTION value type and it describes the bucket boundaries used to create a histogram of the extracted values.

Returned: success

explicitBuckets

complex

Specifies a set of buckets with arbitrary widths.

Returned: success

bounds

list / elements=string

The values must be monotonically increasing.

Returned: success

exponentialBuckets

complex

Specifies an exponential sequence of buckets that have a width that is proportional to the value of the lower bound. Each bucket represents a constant relative uncertainty on a specific value in the bucket.

Returned: success

growthFactor

string

Must be greater than 1.

Returned: success

numFiniteBuckets

integer

Must be greater than 0.

Returned: success

scale

string

Must be greater than 0.

Returned: success

linearBuckets

complex

Specifies a linear sequence of buckets that all have the same width (except overflow and underflow).

Each bucket represents a constant absolute uncertainty on the specific value in the bucket.

Returned: success

numFiniteBuckets

integer

Must be greater than 0.

Returned: success

offset

string

Lower bound of the first bucket.

Returned: success

width

integer

Must be greater than 0.

Returned: success

description

string

A description of this metric, which is used in documentation. The maximum length of the description is 8000 characters.

Returned: success

filter

string

An advanced logs filter (https://cloud.google.com/logging/docs/view/advanced-filters) which is used to match log entries.

Returned: success

labelExtractors

dictionary

A map from a label key string to an extractor expression which is used to extract data from a log entry field and assign as the label value. Each label key specified in the LabelDescriptor must have an associated extractor expression in this map. The syntax of the extractor expression is the same as for the valueExtractor field.

Returned: success

metricDescriptor

complex

The metric descriptor associated with the logs-based metric.

Returned: success

displayName

string

A concise name for the metric, which can be displayed in user interfaces. Use sentence case without an ending period, for example “Request count”. This field is optional but it is recommended to be set for any metrics associated with user-visible concepts, such as Quota.

Returned: success

labels

complex

The set of labels that can be used to describe a specific instance of this metric type. For example, the appengine.googleapis.com/http/server/response_latencies metric type has a label for the HTTP response code, response_code, so you can look at latencies for successful responses or just for responses that failed.

Returned: success

description

string

A human-readable description for the label.

Returned: success

key

string

The label key.

Returned: success

valueType

string

The type of data that can be assigned to the label.

Returned: success

metricKind

string

Whether the metric records instantaneous values, changes to a value, etc.

Some combinations of metricKind and valueType might not be supported.

For counter metrics, set this to DELTA.

Returned: success

type

string

The metric type, including its DNS name prefix. The type is not URL-encoded.

All user-defined metric types have the DNS name `custom.googleapis.com` or `external.googleapis.com`.

Returned: success

unit

string

The unit in which the metric value is reported. It is only applicable if the valueType is `INT64`, `DOUBLE`, or `DISTRIBUTION`. The supported units are a subset of [The Unified Code for Units of Measure](http://unitsofmeasure.org/ucum.html) standard .

Returned: success

valueType

string

Whether the measurement is an integer, a floating-point number, etc.

Some combinations of metricKind and valueType might not be supported.

For counter metrics, set this to INT64.

Returned: success

name

string

The client-assigned metric identifier. Examples - “error_count”, “nginx/requests”.

Metric identifiers are limited to 100 characters and can include only the following characters A-Z, a-z, 0-9, and the special characters _-.,+!*’,()%/. The forward-slash character (/) denotes a hierarchy of name pieces, and it cannot be the first character of the name.

Returned: success

valueExtractor

string

A valueExtractor is required when using a distribution logs-based metric to extract the values to record from a log entry. Two functions are supported for value extraction - EXTRACT(field) or REGEXP_EXTRACT(field, regex). The argument are 1. field - The name of the log entry field from which the value is to be extracted. 2. regex - A regular expression using the Google RE2 syntax (https://github.com/google/re2/wiki/Syntax) with a single capture group to extract data from the specified log entry field. The value of the field is converted to a string before applying the regex. It is an error to specify a regex that does not include exactly one capture group.

Returned: success
