Products

• DX Operational Intelligence

Issue/Introduction

Whilst developing an OI Service View we discovered a mismatch between Devices in UIM and those in OI

It seems OI topology compaction is based on IP & mac address

How can I reconfigure the topology compaction to use "hostname & fqdn" 

Environment

DX OI 24.x

Resolution

1. Download DX OI 24.1 HOTFIX#2 from Broadcom Download Site

2. Apply HOTFIX#2 to DX OI

3. Update the default DX OI Topology compaction rule: run the following API to update the rules:

-EndPoint - http//<doi-adminui endpoint>/oi/v2/tp/correlation/rules/update
-HTTP Method - POST
-Headers -  Authorization :  Bearer <Token - Use the tenant user token / session token of the user who is tenant adminui>  
 For more information how to generate the token please refer to documentation.
-Payload :  <the payload body is included in oi_correlation_rules-payload.txt file attached to the KB>

NOTE: there is not need to restart any DX OI service or UIM oi_connetor or apm_bridge probe..Also, you need to wait for some time for the new compaction rule to get applied as it depends on the size of your inventory
