Issue/Introduction

Symptoms:

  • Devices were removed from the Smarts IP domain, but alerts from those devices remain in the user consoles in Smarts NPM.
  • Automatic synchronization between Smarts NPM and Smarts IP domains is disabled using the following setting in the Smarts IP domain tpmgr_param.conf configuration file:

enableSynchronization  FALSE

  • Synchronization between the Smarts IP and Smarts NPM domains is managed using a cron job as follows:
0 20 * * * /opt/APM DOMAIN NAME/NPM/smarts/bin/dmctl -s <NPM DOMAIN NAME> invoke  ICF_TopologyManager::ICF-TopologyManager addManagedElement <AM DOMAIN NAME> APM



Environment

SMARTS - 10.1.x

SMARTS DM - 2.x

TCSA - 2.x

Resolution

To resolve this issue, you can use the discoverAll command instead of addManagedElement in the cron job used for domain syncrhonization.

dmctl -s <NPM DOMAIN NAME> invoke ICF_TopologyManager::ICF-TopologyManager  discoverAll



Additional Information

Using the discoverAll command will cause Smarts to attempt Open Shortest Path First (OSPF) probing for all existing devices. This will take much longer than just running addManagerElement on Smarts APM domains.
