Looking around on this, is there a guide somewhere (noob guide) that shows how to periodically aggregate data from two sources in my default time index (logs from filebeat to logstash to elasticsearch) to a new index based on my search criteria?

eg. want to bundle up matching data from default index (2 sources) to new index that combines the 2 sources on a matching field and then feed that into Kib

but how do i do this search and create index?

thanks 1000 times

You could use the [Elasticsearch input](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-elasticsearch.html) for Logstash to grab the first doc, then use the [Elasticsearch filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-elasticsearch.html) to grab the second, then merge them accordingly.

As for scheduling, you'd have to use something external to Logstash to do that (eg cron).
