Get average of response time in specific interval


(Ivanandrianto95) #1

I use Filebeat and ELK and I need to display average of response time in specific interval. It has a field response_time but I don't know how to get the average response time each minute. How can I do it?

You can do a date histogram over an aggregation of the average response time, and set the interval of the histogram to the "Minute" option.

Here's a data table visualization I did (over a "bytes" field since my data doesn't have response time):

I don't see response_time in dropdown when I choose average in aggregation

The problem is in Kibana, the type of response_time is string even I've converted it to float in logstash.conf

The mappings are held in Elasticsearch, Kibana uses those mappings to control what it's able to do with the fields.

Check the mapping for your index by running curl -XGET "http://hostname:port/logstash-*/_mapping. If the field is not mapped as a float here, something is going wrong with your logstash.conf.

If your using a mutate filter to do the conversion, this reference could be of help.
