Followed the Topology and Root Cause Analysis setup guidelines found on the UIM Wiki page and we can see our topology in the UMP Relationship Viewer portlet. The net_connect probe was set up to monitor the devices in the topology. We had an outage, but never received any alarms from the fault_correlation_engine include the root cause analysis alarm.
UIM Server: 8.20
discovery_agent and topology_agent probes deployed together on multiple remote hubs.
The interface_poller messages generated by the topology_agent probe were not configured to be sent back to the primary hub from the remote hubs where the topology_agent probes are installed. The fault_correlation_engine probe uses the interface_poller messages to correlate the net_connect alarms in order to generate the appropriate device down or root cause analysis alarms.
Create a queue to send the interface_poller messages back to the primary hub or add this message to an existing ATTACH queue on the secondary hubs where the topology_agent probes are installed.
