Issue
Unknown Host Exception Error is shown when running a report against RespondDB after migration of all the hosts to new Admin-Server.
Cause
On the Reporting Engine, the component reads RabbitMQ Properties from the path /etc/netwitness/platform/legacy_rabbit/nw-re-server.rabbitmq.properties which contains entry of old admin-server. To resolve this, we need to remove this file and recreate it by running a chef recipe.
Resolution
Make sure that the Reporting Engine is not having any customization done in terms of configuration in this RabbitMQ properties file because this chef recipe will set the properties to default. Please take a back of this file before deleting it.
Follow below steps on Admin-Server Node:-
1 systemctl stop rsasoc_re
2 rm -rf /etc/netwitness/platform/legacy_rabbit/nw-re-server.rabbitmq.properties
3 chef-client -r "recipe[nw-re-server::config]" --config /var/lib/netwitness/config-management/client.rb --json-attributes /etc/netwitness/config-management/node.json
4 cat /var/netwitness/re-server/rsa/soc/reporting-engine/rabbitmq.properties (Verify the host name in the output)
5 systemctl restart rsasoc_re
