This functionality is part of the Discovery and Service Mapping Patterns application, which requires the latest version for optimal performance. The discovery populates detailed data into both CMDB and non-CMDB tables, helping you maintain accurate visibility and management of your EMR clusters. Show full answer Show less ## Key Features * **Pattern Activation:** The EMR Cluster discovery pattern is disabled by default and must be enabled manually. Since Visibility Content version 6.28.0, enabling or disabling patterns is no longer considered customization, ensuring you receive updates while retaining your activation settings after upgrades. * **Prerequisites:** Ensure AWS discovery prerequisites are met and verify that EMR clusters are not listed in the Resource Inclusion List to avoid duplicate discoveries. * **Data Population:** * **Non-CMDB Data:** When running the "Amazon AWS - EMR Cluster - Extended Inventory (LP)" pattern, discovery populates non-CMDB AWS tables accessible via ServiceNow's AWS configuration navigation. * **CMDB Data:** The same pattern populates critical EMR cluster details into CMDB tables, including the Cloud Resource \[cmdbcicmpresource\] and AWS EMR Cluster \[cmdbawsemrcluster\] tables. * **CI Relationships:** Relationships are created to reflect hosting infrastructure, specifically linking EMR clusters to AWS Datacenters to provide contextual mapping within the CMDB. * **AWS Tag Discovery:** The pattern collects AWS tags for EMR clusters and stores them in the Key Value \[cmdbkeyvalue\] table, associating metadata tags with the respective cloud resource. ## Key Outcomes * Accurate discovery and mapping of Amazon EMR Clusters in your AWS environment, enhancing your cloud infrastructure visibility. * Comprehensive data capture in both CMDB and non-CMDB tables ensures detailed resource information and relationships are maintained for operational and asset management purposes. * Maintains up-to-date pattern versions and discovery data without losing user-enabled settings during upgrades, ensuring continuous and reliable discovery. * Integration of AWS tags into ServiceNow provides enriched context for EMR clusters, supporting better governance and resource categorization. Discovery and Service Mapping Patterns finds Amazon EMR Clusters on your cloud environment running on EC2. 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-emr-cluster__section_rpj_fj2_bgc} 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-emr-cluster__activating-disabled-pattern-not-customization} Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables. ## Data stored in non-CMDB tables {#aws-emr-cluster__section_aq4_qkq_hfc} Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - EMR Cluster - 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-emr-cluster__table_non_cmdb__entry__2} | Field | Description | |-|-| | Name \[name\] | Name of the EMR cluster. | | Object ID \[object_id\] | The Amazon Resource Name (ARN) of the EMR cluster. | | Cluster ID \[cluster_id\] | The unique identifier of the EMR cluster. | | State \[state\] | Current state of the EMR cluster.
