Entities, lookup information, and metrics for Google Cloud Platform

This topic explains the predefined metrics that are available from the Google Cloud Platform services and how they are mapped to the TrueSight Capacity Optimization metrics. Most of the metrics are available to all your GCP projects.

Entity list

The Google Cloud Platform - GCP API Extractor monitors the following entities:

Project - Google Cloud
Virtual Machine - Google Cloud

Entity relationship

The following table shows the entity relationship details:

Parent entity

Child entity

Relationship type

Project - Google Cloud

(project:gcp)

Virtual Machine - Google Cloud

(gm:gcp)

PROJECT_CONTAINS_GM

Lookup information

The following table contains the lookup information for the GCP entities.

Entity type	Lookup fields
	Strong	Weak
Project - Google Cloud	PROJECT_ID	Not applicable
Virtual Machine - Google Cloud	INSTANCE_ID	Not applicable
