## Summary of GCP Storage pattern-based discovery

The GCP Storage pattern-based discovery enables ServiceNow customers to identify and map Google Cloud Platform (GCP) persistent disks and snapshots within their cloud environment.
This discovery populates essential configuration item (CI) data into the ServiceNow CMDB, supporting effective cloud resource management and visibility.

To utilize this pattern, customers must ensure they meet the GCP discovery prerequisites, including having the latest Discovery and Service Mapping Patterns application version installed from the ServiceNow Store.

## Data Collected and CMDB Population

During discovery, the pattern collects detailed information about various GCP storage-related resources and stores them in corresponding CMDB tables:

* **Cloud Service Account:** Includes project account ID, object ID, and datacenter type.
* **Availability Zone:** Captures zone name, description, and state (Available or Terminated).
* **Google Datacenter:** Stores datacenter/region name, region info, unique object ID, and description.
* **Storage Volume (Persistent Disk):** Records unique IDs, name, storage type (e.g., pd-standard, pd-ssd), size in bytes, operational state, install status, and description.
* **Storage Volume Snapshot:** Contains unique ID, snapshot name, source volume name, and capacity.
* **Virtual Machine Instance:** Tracks total size of attached disks in GB.

## CI Relationships

The pattern automatically creates relationships between discovered CIs to reflect the GCP storage architecture:

* Storage Volumes are hosted on Google Datacenters and Availability Zones.
* Storage Volume Snapshots are contained by and replicate Storage Volumes.
* Storage Volumes are associated with Cloud Service Accounts.
* Google Datacenters contain Availability Zones and are hosted on Cloud Service Accounts.
* Key Value entries reference Storage Volumes and Storage Volume Snapshots to capture GCP labels.

## GCP Tag Discovery

The pattern collects GCP resource labels and stores them as key-value pairs in the **cmdbkeyvalue** table. These entries link to both Storage Volume and Storage Volume Snapshot CIs, enabling enhanced tagging and categorization of storage resources within the CMDB.

## Benefits for ServiceNow Customers

* Automated discovery and mapping of GCP storage resources into the CMDB improve cloud asset visibility.
* Rich metadata and relationships support better impact analysis, change management, and compliance reporting.
* Integration of GCP labels as key-value pairs facilitates custom tagging and resource classification aligned with cloud policies.
* Supports ongoing cloud governance by providing accurate, up-to-date storage resource data within the ServiceNow platform.  
Discovery and Service Mapping Patterns finds GCP persistent disks and snapshots on your cloud environment. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Pattern-based discovery and mapping requirements {#gcp-storage-pattern__section_rpj_fj2_bgc}

Verify the GCP discovery prerequisites section in [Google Cloud Platform (GCP) Cloud discovery using Patterns](https://www.servicenow.com/docs/hH4wPjzyLr0pmFmj6Ib5TA "Discovery and Service Mapping Patterns uses patterns to discover components of the Google Cloud Platform (GCP) deployment during horizontal discovery. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

## Data collected by Discovery during horizontal discovery {#gcp-storage-pattern__section_ggp_ql2_bgc}

Discovery populates the data in the CMDB when running the Google Cloud Platform (GCP) - Storage pattern.
