You might wonder why I took Paris accidentology to illustrate the logging analytics use case. Well, I want to break into pieces the unfair reputation that sometimes sticks in people's minds when it comes to visualization with Kibana. Kibana is a visualization application; it's not only meant to be used by IT operations teams to monitor their application's health.
The name of the use case you are dealing with is just an abstraction that defines the use profile over your data. You can do logging analytics and actually deal with healthcare data, and do application monitoring with the same logs. It just depends on the nature and content of your data, also on the use profile of your visualization. If I put on my security hat, then I'll do security analytics on top of the ingested logs.
The Paris accidentology use case will help us to go through most of the visualizations and features that Kibana offers to implement logging analytics.
