{#google-gcp-discovery-pattern__table_anf_bxf_tsb}

## Requirements for GCP discovery {#google-gcp-discovery-pattern__section_l3z_nwb_tfc}

Verify that the applications are up to date.
:
    * Discovery and Service Mapping Patterns starting version 1.8.0 (September 2023)
    * CMDB CI Class Models starting version 1.49.0 (September 2023)
    * Visibility Content starting version 6.13.0 (September 2023)
    {#google-gcp-discovery-pattern__ul_aln_qlb_5yb}

Verify the MID Server requirements
:
    * Use a dedicated MID Server for cloud discovery. The MID Server must have 16 Cores, 8 GB with 4 GB Java Virtual Machine (JVM) memory allocation. For information on verifying MID Server specifications, see KB article [KB2156327](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2156327).
    * Deploy and connect the dedicated MID Server with internet access.
    * For more information on the MID Server configurations, see [Install and configure MID Servers to access cloud environments](https://www.servicenow.com/docs/J5R6fEzDsXUAwkST18d7jg "Install and configure the MID Servers correctly to enable ITOM products to access to the cloud resources.").
    {#google-gcp-discovery-pattern__ul_xdh_b33_ydc}

Verify Google Cloud BigQuery and Google Cloud Bigtable requirements
:   To discover Google Cloud BigQuery and Google Cloud Bigtable, navigate to AllDiscoveryMID ServerProperties and ensure that the sn_itom_pattern.google_dbservice_table_collection property is set to True.

Verify user role settings

:   Set the user permission for the Google Cloud Platform member to Viewer:

    1. In the Google Cloud Platform console, navigate to IAM.
    2. Select the relevant member from the list and click the Edit icon.
    3. In the Edit permissions window, select <kbd class="ph userinput">Viewer</kbd> from the Role list.
    4. Click Save.
    {#google-gcp-discovery-pattern__ol_w2h_ctl_b3b}

Configure Google API Credentials
:   For more information, see [Configure the Google API credentials for Cloud Discovery](https://www.servicenow.com/docs/jDr5WSecOCRZZ0pZXlVAUQ "Create Google API credentials to allow Cloud Discovery to access the data on your Google account securely.").

Create a Google Cloud Platform service account
:   For more information, see [Create GCP service accounts](https://www.servicenow.com/docs/aPouvBFAvaXojnj8qxYBkQ "Create Google Cloud Platform (GCP) service accounts on the ServiceNow AI Platform to access your GCP account during GCP discovery.").

Enable collecting cloud logging events
:   The Google Cloud Platform patterns can collect cloud logging events generated by the native Google Cloud APIs. [Configure the Google Cloud Logging service to auto-update the CMDB](https://www.servicenow.com/docs/MaVDYaoPNWQMPtPGWD6m2g "You can activate the Google Cloud Logging (formerly Stackdriver Logging) service to auto-update Configuration Management Database (CMDB) configuration items (CI) data whenever Google Cloud Connector or your Google account makes a life-cycle state or configuration change to a Google Cloud Platform (GCP) resource. As a result, the CI data in the CMDB is updated without having to wait for Discovery to run.").

Activate the cloud-related CI relationships
:   To include discovered components into service instances, enable CI relationships used in tag-based discovery by Service Mapping. These CI relationships are available from the 1.0.68 release on the ServiceNow Store. For operational steps, see [Tag-based discovery configuration](https://www.servicenow.com/docs/WMqYQ9cztLwkmoyPJWnmIw "You can refine the default configuration to control which CIs Service Mapping includes in application services during the tag-based discovery process.").

Verify that a Discovery schedule is configured
:   For more information, see [Create a GCP Discovery schedule in Discovery Admin Workspace](https://www.servicenow.com/docs/FbrkPQwIKzGpvW5OnXDNPA "Use the Discovery Admin Workspace dashboard to create a Google Cloud Platform (GCP) Discovery schedule.").

(Optional) Populate Service Account and Logical Datacenter fields in cloud CIs
:   Starting with Discovery and Service Mapping Patterns version 1.30.2, you can improve query performance by populating Service Account and Logical Datacenter fields directly in cloud CIs. For more information, see [Improved query performance with direct field population in CI tables](https://www.servicenow.com/docs/H_wfVmrRA2K_BT9VRkb6iQ "The Populate Service Account and LDC IN CMDB scheduled job populates the Service Account and Logical Datacenter fields in cloud configuration item (CI) tables, and the Virtual Machine Object field in the Hardware [cmdb_ci_hardware] table. This direct population reduces query complexity and improves query performance.").

## Verify the REST API Permissions {#google-gcp-discovery-pattern__id_ppz_r33_ydc}

Download the [Cloud Discovery patterns spreadsheet](https://downloads.docs.servicenow.com/resource/enus/api/servicenow-discovery-patterns-api-details.xlsx) so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available
quarterly, so check periodically to be sure you have the latest version of the spreadsheet.{#google-gcp-discovery-pattern__cloud-discovery-api-paragraph}

## Data collected by Service Mapping during tag-based discovery {#google-gcp-discovery-pattern__section_mtq_nbg_ppb}

Service Mapping uses tag-based discovery to create service instance maps including the Cloud components. The Service Mapping application comes with the following preconfigured CI relationships used for tag-based discovery. These CI relationships are available from the 1.0.68 release on the ServiceNow Store. {#google-gcp-discovery-pattern__id_yqp_xhy_qpb__entry__3}

| CI | Relationship | CI |
|-|-|-|
| Configuration Item \[cmdb_ci\] | Hosted on::Hosts | Logical Datacenter \[cmdb_ci_logical_datacenter\] |
| Logical Datacenter \[cmdb_ci_logical_datacenter\] | Hosted on::Hosts | Cloud Service Account \[cmdb_ci_cloud_service_account\] |
