I am testing a processing performance of Logstash and Elasticsearch injection, does anyone know is there any log or measurement data you can check to see how fast Logstash processing one single CSV file and how fast the aggregate data being sent/injected to Elasticsearch? thanks!

You could use the [pipeline stats](https://www.elastic.co/guide/en/logstash/current/node-stats-api.html#pipeline-stats) API.
