Using a DBConfiguration.xml it was configured that DataMiner will write to two ElasticSearch clusters on geographically redundant sites.

I'd like to verify that this is working ok and that DataMiner indeed writes to both clusters.  I want to be sure that if a failover switch happens that everything will work ok.

How do I check that data is being written to both sites and how can I trigger writes being done to the ElasticSearch and where do I check the data that was written in that action?
