Can anyone teach me or point me to a straightforward tutorial/doc for my use case:

I already have an index of event logs where each event has a duration field. That is the time in milliseconds each request to the server took.

I ideally would like to see only those events that falls outside of the 99% duration, 90%, 50%.

Is there a way to do this through Kibana Visualizations/Timelion?

There is no way of doing this without some manual steps. You could have a metric visualization that shows the 99%, 90%, and 50% duration values. Then you could manually create a lucene query that filters the data to be above that value to view the targeted documents.

Doing this in an automated way is an interesting usecase. I would recommend opening a enhancement issue at [https://github.com/elastic/kibana/issues](https://github.com/elastic/kibana/issues) to track the idea.
