Logstash: how to create one index per host?

Question

linux

Hello! They come from Filebeat, then Logstash passes them to Elasticsearch. Now a new index is created every day:

input {
beats {
port => 5044
}
}
filter {
date {
match => [ "logdate", "ISO8601" ]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
sniffing => true
manage_template => false
index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
# document_type => "%{[@metadata][type]}"
# document_type => "doc"
document_type = > "log"
}
}

This is inconvenient + a large number of indexes has a bad effect on performance.
How to make it so that for each hostname there is a separate index? There are few monitored servers, there will not be a large number of indexes, and it will become more convenient to manage.

Answer 1

Probably something like this:
index => "%{host}"
