    Summary of Amazon ElastiCache Snapshot pattern-based discovery

    The Amazon ElastiCache Snapshot pattern-based discovery in ServiceNow enables automated identification and mapping of ElastiCache snapshot resources within your AWS cloud environment. This functionality is part of the Discovery and Service Mapping Patterns application, helping you maintain accurate and up-to-date configuration data for ElastiCache snapshots in your CMDB and related non-CMDB tables.

    Key Features

    • Pattern Activation: The ElastiCache Snapshot discovery pattern is disabled by default but can be enabled without being considered a customization, ensuring it receives ongoing updates with new releases.
    • Prerequisites and Configuration: Requires AWS discovery prerequisites and removal of duplicate resources from the Resource Inclusion List to avoid duplicate discovery results.
    • GovCloud Support: Discovery of AWS GovCloud (US) accounts requires specific datacenter URL configuration for AWS service accounts.
    • Data Population: Discovers and populates ElastiCache snapshot data into both CMDB and non-CMDB tables:
      • Non-CMDB data via the Amazon AWS - ElastiCache Snapshot - Extended Inventory (LP) pattern, accessible under Configuration > AWS.
      • CMDB data including resource details and operational status for snapshot configuration items.
    • Key Data Attributes: Captured fields include ARN, snapshot name, status, cache cluster ID, engine type and version, and relationships to AWS datacenter and cloud resource records.
    • CI Relationships: Automatically creates relationships such as "Hosted on" linking snapshots to AWS datacenters and references to cloud resource CIs.
    • Tag Discovery: Collects AWS tags associated with snapshots and stores them in the Key Value table for enhanced resource classification and querying.

    Practical Benefits for ServiceNow Customers

    This discovery pattern enables you to efficiently track and manage AWS ElastiCache snapshots within your ServiceNow CMDB, supporting:

    • Improved visibility into snapshot resources and their configurations.
    • Accurate relationship mapping for impact analysis and service mapping.
    • Better governance and compliance through tag collection and resource status monitoring.
    • Seamless integration with AWS GovCloud environments for comprehensive discovery coverage.

    By enabling this pattern and configuring discovery schedules accordingly, you ensure your CMDB reflects a current and reliable state of your ElastiCache snapshots, facilitating operational efficiency and informed decision-making.

    Discovery and Service Mapping Patterns finds AWS services on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Pattern-based discovery and mapping requirements

    Verify the AWS discovery prerequisites
    For more information, see the prerequisites section in AWS discovery using patterns.
    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.
    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.
    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.

    Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

    Data stored in non-CMDB tables

    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 All > Configuration > AWS. You can also search the navigation filter for the specific pattern name.

    Table 1. AWS ElastiCache - Snapshot [cmdb_aws_elasticache_snapshot]
    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.

    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.

    Table 2. Cloud Resource [cmdb_ci_cmp_resource]
    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.

    CI relationships

    The Amazon AWS - ElastiCache Snapshot - Extended Inventory (LP) pattern creates these relationships to support Amazon ElastiCache Snapshot discovery.

    CI Relationship CI
    Cloud Resource [cmdb_ci_cmp_resource] Hosted on::Hosts AWS Datacenter [cmdb_ci_aws_datacenter]
    AWS ElastiCache - Snapshot [cmdb_aws_elasticache_snapshot] References Cloud Resource [cmdb_ci_cmp_resource]

    AWS tag discovery

    The pattern collects tags and populates them in the Key Value [cmdb_key_value] table.
    Table 3. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
