## Summary of Amazon ElastiCache Snapshot pattern-based discovery

The Amazon ElastiCache Snapshot pattern-based discovery is part of the Discovery and Service Mapping Patterns application in ServiceNow.
It enables automated discovery of ElastiCache snapshot resources within your AWS cloud environment, populating relevant data into both CMDB and non-CMDB tables.
This pattern helps you maintain an accurate configuration management database (CMDB) by identifying ElastiCache snapshot details, statuses, and relationships.
Show full answer Show less  
To use this pattern effectively, you must meet AWS discovery prerequisites, manage resource inclusion lists to prevent duplicate discovery, and enable the ElastiCache Snapshot pattern, which is disabled by default. The pattern supports discovery of AWS GovCloud accounts through appropriate configuration.

## Key Features

* **Pattern Activation and Updates:** The ElastiCache Snapshot pattern is disabled by default but can be enabled without customization concerns as it receives ongoing updates. After upgrades, the pattern resets to the latest version while retaining previous activation status.
* **Data Population in ServiceNow:**
  * **Non-CMDB Tables:** The pattern populates detailed ElastiCache snapshot attributes in a non-CMDB table \[cmdbawselasticachesnapshot\], including snapshot ARN, name, status, cache cluster ID, engine type and version, and references to cloud resources.
  * **CMDB Tables:** Key snapshot resource metadata is stored in the Cloud Resource table \[cmdbcicmpresource\], with fields such as ARN, name, resource type (set to AWS::ElastiCache::Snapshot), installation status, and operational status.
  * **Tag Collection:** AWS tags associated with snapshots are collected and stored in the Key Value \[cmdbkeyvalue\] table for enhanced resource categorization and management.
* **CI Relationships:** The pattern establishes relationships between ElastiCache snapshots and AWS datacenters to reflect hosting and resource references accurately in the CMDB.

## Practical Considerations for ServiceNow Customers

* Ensure you have met the AWS discovery prerequisites and removed relevant resources from the Resource Inclusion List to avoid duplicate entries.
* Activate the ElastiCache Snapshot pattern through the Discovery and Service Mapping Patterns application to start discovering snapshots.
* Configure Discovery schedules appropriately, especially when working with AWS GovCloud accounts, by specifying datacenter URLs in AWS service accounts.
* Review discovered snapshot data in both CMDB and non-CMDB tables to gain visibility into snapshot status, engine details, and relationships for operational and asset management.
* Utilize collected AWS tags to enhance filtering, reporting, and automation related to ElastiCache snapshots within your ServiceNow environment.  
Discovery and Service Mapping Patterns finds AWS services 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 {#aws-elasticache-snapshot__selection_ipy_53n_jfc}

Verify the AWS discovery prerequisites
:   For more information, see the prerequisites section in [AWS discovery using patterns](https://www.servicenow.com/docs/NFaTlkGaSxMWb2bQPsCnCA "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud 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.").

Remove resources from the Resource Inclusion List table
:   Verify that the relevant resource isn't listed in the Resource Inclusion List \[sa_cloud_inventory_resource_whitelist\] table to avoid duplicate discovery. For more information on removing resources from the Resource
    Inclusion List, see [AWS Resource Inventory discovery with Patterns](https://www.servicenow.com/docs/0pDNq0441mpy~sExfQvvqA "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

Enable the relevant pattern
:   The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see [Activate a disabled pattern](https://www.servicenow.com/docs/aypCYVQdO8oFebLMLEI89g "If you want to use a pattern for discovery that's disabled by default, activate it manually.").{#aws-elasticache-snapshot__activating-disabled-pattern-not-customization}

Configure the Discovery schedule to support GovCloud
:   Discovering AWS GovCloud (US) accounts requires using a datacenter URL when setting up an AWS service account. For more information, see [Create AWS service accounts](https://www.servicenow.com/docs/vpueuFRHMWLNi6dzsJv94A "Create AWS service accounts on the ServiceNow AI Platform to access your AWS account during AWS discovery.").
Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

## Data stored in non-CMDB tables {#aws-elasticache-snapshot__section_aq4_qkq_hfc}

Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - ElastiCache Snapshot - Extended Inventory (LP) pattern.

You can review the non-CMDB
AWS tables by navigating to AllConfigurationAWS. You can also search the navigation filter for the specific pattern name.  
{#aws-elasticache-snapshot__section_aq4_qkq_hfc__entry__2}

| Field | Description |
|-|-|
| Object Id \[object_id\] | The Amazon Resource Name (ARN) uniquely identifying the ElastiCache snapshot. |
| Name \[name\] | The name of the snapshot. |
| Status \[status\] | The current status of the snapshot. |
| Cache Cluster ID \[cache_cluster_id\] | The identifier of the cache cluster from which the snapshot was taken. |
| Configuration Item \[configuration_item\] | References the Cloud Resource \[cmdb_ci_cmp_resource\] table. |
| Engine \[engine\] | The type of caching engine used. For example: Redis or Memcached. |
| Engine Version \[engine_version\] | The version of the cache engine used for the snapshot. |
[Table 1. AWS ElastiCache - Snapshot \[cmdb_aws_elasticache_snapshot\]]

## Data stored in CMDB tables

Discovery and Service Mapping Patterns application populates data in the CMDB when running the Amazon AWS - ElastiCache Snapshot - Extended Inventory (LP) pattern.  
{#aws-elasticache-snapshot__entry__18}

| Field | Description |
|-|-|
| Object ID \[object_id\] | The ARN uniquely identifying the ElastiCache snapshot. |
| Name \[name\] | The name of the snapshot. |
| Resource type \[resource_type\] | Type of resource. The value is set to AWS::ElastiCache::Snapshot. |
| Install Status \[install_status\] | Install status of the resource. Default value is Installed. |
| Operational status \[operational_status\] | Operational status of the resource. Default value is Operational. |
[Table 2. Cloud Resource \[cmdb_ci_cmp_resource\]]

## CI relationships

The Amazon AWS - ElastiCache Snapshot - Extended Inventory (LP) pattern creates these relationships to support Amazon ElastiCache Snapshot discovery.  
{#aws-elasticache-snapshot__entry__31}

| CI | Relationship | CI |
|-|-|-|
| Cloud Resource \[cmdb_ci_cmp_resource\] | Hosted on::Hosts | AWS Datacenter \[cmdb_ci_aws_datacenter\] |

## AWS tag discovery {#aws-elasticache-snapshot__section_ezc_jwt_jfc}
