This feature groups devices by their configuration hash values, allowing you to see patterns in configuration drift and apply fixes to entire groups at once. + +## Overview + +When configuration compliance issues affect multiple devices with identical misconfigurations, the traditional approach of reviewing each device individually can be time-consuming and inefficient. The Configuration Hash Grouping feature solves this by: + +- Automatically grouping devices with identical configuration hashes +- Providing a unified view of devices sharing the same configuration issues +- Enabling bulk remediation operations on groups of devices +- Simplifying troubleshooting of widespread configuration problems + +## How It Works + +The Configuration Hash Grouping feature uses a three-model architecture to efficiently organize and display configuration data: + +### Architecture Components + +1. **ConfigHashGrouping**: Groups devices with identical configuration hashes +2. **ConfigComplianceHash**: Links individual devices to configuration hash groups +3. **ConfigCompliance**: Provides the base compliance data (existing model, modified for integration) + +### Hash Generation Process + +When configuration compliance jobs run, the system: + +1. Computes SHA-256 hashes of device configuration content +2. Creates or finds existing ConfigHashGrouping records for each unique hash +3. Links devices to the appropriate hash groups via ConfigComplianceHash records +4. Stores the actual configuration content once per unique hash for display purposes + +This approach eliminates duplicate storage while maintaining fast access to configuration data for analysis. + +## Accessing Configuration Hash Grouping + +To access the Configuration Hash Grouping feature: + +1. Navigate to **Golden Config** in the main navigation menu +2. Under the **Manage** section, select **Hash Grouping Report** +3.

By grouping devices with identical configuration hashes, it provides network administrators with powerful tools for identifying, analyzing, and resolving configuration issues at scale. The feature's three-model architecture ensures excellent performance while maintaining data integrity, and its seamless integration with existing Golden Config functionality makes it immediately useful in any network automation workflow. diff --git a/mkdocs.yml b/mkdocs.yml index bf6db23ac..ea3daa620 100644 --- a/mkdocs.yml +++ b/mkdocs.yml @@ -122,6 +122,7 @@ nav: - Navigate Configuration
