• CA Unified Infrastructure Management SaaS (Nimsoft / UIM)

Issue/Introduction

udm_manager queue is always displayed with yellow status.

We also noticed the queue is always empty and Id column in IM -> Hub Configuration -> Status is missing the discovery_server subscriber

Environment

Release : Any

Component : UIM - UDM

Resolution

1. Open the discovery_server.cfg and remove the "publish_to_udm = no" setting from the <udm_manager> section

From

   <udm>
      only_network_interface_config_items = true
      included_probes = "discovery_agent, snmpcollector, spectrumgtw, nfa_inventory, ada_inventory"
      publish_to_udm = no
   </udm>

To

   <udm>
      only_network_interface_config_items = true
      included_probes = "discovery_agent, snmpcollector, spectrumgtw, nfa_inventory, ada_inventory"
    </udm>

2. Deactivate/activate the discovery_server and udm_manager

Additional Information

See article below which mentions the "publish_to_udm = no" as a temporary workaround for a probeDiscovery queue issue
