Test data in trial cloud

Hi, I'm using trial for Elasticsearch cloud. I have not yet post any data into my cluster but Marvel shows me that there are already thousands of the documents being stored in my test cluster - is it being pre-populated with some test data?

You could run a _search operation to have a look at these documents. Maybe these are documents that Marvel internally generates in order to keep some history about your cluster for troubleshooting.

Thanks!
