Something like https://www.elastic.co/guide/en/logstash/1.5/plugins-filters-metrics.html may help.

ok, but how can I bring everything to a file ?
for example , when loading a file , I wish the same time was written on a text file ( .log ) the name of the file loading , the lines of the records and files loaded on ES .
it's possible?
