I am currently using metricbeat to monitor the health and metrics of our servers and application on those servers. I then upload that to elasticsearch and then pull it from elasticsearch using .NET and NEST. NEST parses the JSON data structure from elasticsearch and maps it to our .NET objects.
Is there a way to change the indexing of certain fields (e.g. "beat.hostname" to just "hostname")? This would make it a great deal easier to map the elasticsearch JSON object to my .NET object.
