## Summary of Amazon CloudWatch Log Group pattern-based discovery

This pattern enables ServiceNow customers to discover Amazon CloudWatch Log Groups within their AWS cloud environments using the Discovery and Service Mapping Patterns application.
It automates the identification and inventory of these log groups, ensuring accurate and up-to-date data in both the Configuration Management Database (CMDB) and non-CMDB tables.

## Key Features

* **Pattern Activation:** The CloudWatch Log Group discovery pattern is disabled by default and must be enabled to function. With Visibility Content version 6.28.0 or later, enabling or disabling patterns is no longer treated as customization, ensuring patterns receive updates after upgrades.
* **Prerequisites and Preparation:** Customers must verify AWS discovery prerequisites and ensure that CloudWatch Log Groups are not listed in the Resource Inclusion List table (\[sacloudinventoryresourcewhitelist\]) to prevent duplicate discoveries.
* **Data Population:** The pattern populates detailed information about CloudWatch Log Groups in both non-CMDB tables (such as *cmdbawscloudwatchlog* ) and CMDB tables (such as *cmdbcicmpresource*), capturing attributes like ARN, storage class, stored bytes, operational status, and resource type.
* **Relationships and References:** The pattern establishes key relationships, such as linking CloudWatch Log Groups to their hosting AWS Datacenters, and manages references within the CMDB to maintain resource context and integrity.
* **Tag Collection:** AWS tags associated with CloudWatch Log Groups are discovered and stored in the Key Value table (*cmdbkeyvalue*), enabling richer metadata management and reporting.

## Practical Use and Benefits

By implementing this discovery pattern, ServiceNow customers can achieve comprehensive visibility of their CloudWatch Log Groups, facilitating better resource management, compliance, and operational insight. The integration with CMDB ensures that discovered log groups are tracked alongside other configuration items with accurate relationships and metadata, supporting effective service mapping and IT operations.  
Discovery and Service Mapping Patterns finds Amazon CloudWatch Log Groups 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-cloudwatch-log-group__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-cloudwatch-log-group__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-cloudwatch-log-group__section_aq4_qkq_hfc}

Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - CloudWatch Log Group - 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-cloudwatch-log-group__table_non_cmdb__entry__2}

| Field | Description |
|-|-|
| Name \[name\] | Name of the Amazon CloudWatch log group. |

## Data stored in CMDB tables {#aws-cloudwatch-log-group__section_ggp_ql2_bgc}

Discovery and Service Mapping Patterns application populates data in the CMDB when running the Amazon AWS - CloudWatch Log Group - Extended Inventory (LP) pattern.  
{#aws-cloudwatch-log-group__table_cmdb__entry__2}

| Field | Description |
|-|-|
| Object ID \[object_id\] | ARN of the log group. |

## CI relationships {#aws-cloudwatch-log-group__section_dc4_ghc_dgc}

The Amazon AWS - CloudWatch Log Group - Extended Inventory (LP) pattern creates the following relationships and references to support Amazon CloudWatch Log Group discovery. References link to records in other tables and don't appear in the CI Relationship \[cmdb_rel_ci\] table.
