Kibana is the natural UI choice for partnering Elasticsearch, and it has the advantage of being Web-based and Dockerized, so it’s cross-platform and easy to share. But PowerBI is a lot more powerful, and the multitude of available connectors mean it’s easy to build a single dashboard which pulls data from multiple sources.
Using Elasticsearch for one of those sources is simple, although it will need some custom work to query your indexes and navigate the documents to get the field you want. You can even publish your reports to PowerBI in the cloud and limit access using Azure Active Directory – which gives you a nice, integrated security story.
I tend to be very hard on Kibana, particularly because it makes the easy stuff easy and the hard stuff impossible, so I think that this is an interesting alternative to Kibana.
