How do I know when a DX Netops Virtual Network Assurance gateway has completed removing SDN items from the Data Aggregatoe after deletion?

We need to re-add the gateway but need to wait until the DA cleans up its items before re-adding.

What log messages in DX Netops Performance Management can we look for to verify the Data Aggregator cleanup is complete?

Environment

Release : DX Netops Performance Management 20.2.9 and later

Component : DX Netops Performance Management, DX Netops Virtual Network Assurance

Resolution

****Note that deleting a VNA gateway will remove all the VNA items (the SNMP items would remain) AND the corresponding data from DX Netops Performance Management****
****Note that when the items come back they would have new IDs so this would also impact any views, etc pinned to those items****

1) Delete the gateway as noted here:

2) Wait for the DA to complete the removal of the SDN items.

On the DA, in the /opt/IMDataAggregator/apache-karaf-2.4.3/data/log/karaf.log (Default Path) you will see log messages such as:


INFO  | tp840658619-1168 | YYYY-MM-DD HH:MM:SS,### | SDNGatewayChangeListener | mpl.sdn.SDNGatewayChangeListener   80 | ager.core.collector.impl |       | SDN Gateway ######## has been deleted - cleaning up its associated Inventory
INFO  | tp840658619-1168 | YYYY-MM-DD HH:MM:SS,### | SDNGatewayChangeListener | mpl.sdn.SDNGatewayChangeListener   99 | ager.core.collector.impl |       | Finished cleaning up inventory associated with SDN Gateway #######

Where ####### would be the id of your gateway.

Also once complete the following URL would have no items if you only had one VNA gateway:
