If you have both the start time (timestamp) and end time in the same event then [this](https://discuss.elastic.co/t/time-difference-between-two-fields-in-a-csv-using-ruby-plugin/122115/2?u=badger) might help.

If you have the start time and end time in different events then an [aggregate filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-aggregate.html) might work for you.
