One elasticsearch to input from other elasticsearches

[Marta_Zagrajek]

Hi there
I want to create one big elastichsearch cluster which will combine logs from other elasticsearch clusters (even up to 10).
Is there a possibility to do that using logstash?
My further explanation:
I have multiple machines with Apache, and multiple machines with Tomcat. They have different ELK clusters. So if there is something wrong, we need to search first Apache ELK, then Tomcat ELK and even different, more specifies ELKs.
I noticed that logstash can output to multiple ELKs using IP:port but I did not find information about input way like this.
Thank you kindly for help
