## Summary of Google Cloud Platform (GCP) AlloyDB for PostgreSQL discovery using patterns

The Google Cloud Platform (GCP) AlloyDB for PostgreSQL discovery pattern enables ServiceNow customers to automatically discover AlloyDB for PostgreSQL resources within their GCP environment during horizontal discovery.
This pattern is part of the Discovery and Service Mapping Patterns application and requires verifying GCP discovery prerequisites for successful operation.
When executed, it populates the Configuration Management Database (CMDB) with detailed AlloyDB-related configuration items (CIs) and their relationships.

## Key Features

* **Discovery of AlloyDB Resources:** Automatically identifies AlloyDB clusters, databases, availability zones, cloud service accounts, and Google datacenters.
* **CMDB Population:** Captures key attributes of discovered resources such as cluster IDs, operational and install statuses, cluster types, CPU count, IP addresses, and replication types.
* **Relationship Mapping:** Establishes and visualizes relationships among AlloyDB instances, clusters, availability zones, and datacenters to provide a clear dependency view on the Dependency Views map.
* **Tag Collection:** Gathers and records tags associated with AlloyDB clusters and databases into the Key Value \[cmdbkeyvalue\] table, supporting enhanced classification and filtering.

## Key Outcomes

* Complete, up-to-date visibility of AlloyDB for PostgreSQL resources in the CMDB, supporting accurate asset and service management.
* Clear understanding of the operational state and configuration of AlloyDB clusters and databases, facilitating monitoring and troubleshooting.
* Improved impact analysis and change management through well-defined CI relationships connecting databases, clusters, availability zones, and datacenters.
* Enhanced organization and searchability of AlloyDB resources using collected tags stored within key-value pairs linked to the respective CIs.  
Discovery and Service Mapping Patterns uses the Google Cloud Platform (GCP) - AlloyDB for PostgreSQL pattern to discover AlloyDB for PostgreSQL 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.

## Pattern-based discovery and mapping requirements {#gcp-alloydb-postgresql-patterns__section_txl_rj2_wfc}

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-alloydb-postgresql-patterns__section_s2v_tj2_wfc}

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