                At present, only this stupid way to implement, convert Request_time to float I remember the last time I had written an article on how to calculate the average, that is, in Logstash agent.conf  The data is int or float float, otherwise ... If it is not a number, then you will find that you are in the Kibana of the steps, there is no number field to choose from.
