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 |
