This functionality is part of the Discovery and Service Mapping Patterns application, designed to populate both configuration management database (CMDB) and non-CMDB tables with detailed ElastiCache snapshot data. This capability helps ServiceNow customers maintain accurate and up-to-date visibility of their caching resources on AWS. Show full answer Show less ## Key Features * **Pattern Activation:** The ElastiCache Snapshot discovery pattern is disabled by default and requires manual activation. Since version 6.28.0 of Visibility Content, activating or deactivating patterns is simplified and preserves update compatibility. * **Prerequisites:** Ensure AWS discovery prerequisites are met, and verify that ElastiCache snapshot resources are removed from the Resource Inclusion List to avoid duplicate discovery. * **GovCloud Support:** Discovery supports AWS GovCloud by requiring a datacenter URL configuration in the AWS service account setup. * **Data Storage:** Discovery populates: * Non-CMDB tables, specifically when running the "Amazon AWS - ElastiCache Snapshot - Extended Inventory (LP)" pattern, for detailed snapshot metadata. * CMDB tables, notably the **Cloud Resource \[cmdbcicmpresource\]** table, to register snapshot configuration items with key attributes and statuses. * **CI Relationships:** The pattern creates relationships linking ElastiCache snapshots to AWS datacenters and associated cloud resources, supporting comprehensive service mapping. * **Tag Discovery:** AWS tags on ElastiCache snapshots are collected and stored in the Key Value \[cmdbkeyvalue\] table for enhanced resource management and filtering. ## Key Outcomes * Accurate discovery and continuous synchronization of ElastiCache snapshot resources within your ServiceNow CMDB and supplemental tables. * Enables service mapping to incorporate ElastiCache snapshots, improving visibility into caching infrastructure dependencies. * Supports efficient AWS resource management by capturing detailed metadata including snapshot status, engine type and version, and cache cluster identifiers. * Facilitates compliance and operational insights through up-to-date tagging information and resource relationships. 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 {#aws-elasticache-snapshot__selection_ipy_53n_jfc} Verify the AWS discovery prerequisites : For more information, see the prerequisites section in [Amazon AWS Cloud components discovery using patterns](https://servicenow-prod.fluidtopics.net/nnBwzYmMo_kpTZpG3y5~xQ "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources may 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 [Amazon Web Services (AWS) Resource Inventory](https://servicenow-prod.fluidtopics.net/U2bwxjeyIbyEXySOOJQkYA "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources may 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://servicenow-prod.fluidtopics.net/R5W5GP640V_5uNIhVNRPCw "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://servicenow-prod.fluidtopics.net/CvTA68TY3ph_FRR49RbdPg "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.
