Hello, I just installed ELK on my server by following the tutorial [https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elastic-stack-on-ubuntu-18-04](https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elastic-stack-on-ubuntu-18-04) and I have some questions:
- what is the difference between the command :
`# sudo metricbeat setup --template -E output.logstash.enabled=false -E 'output.elasticsearch.hosts=["localhost:9200"]'`
`# sudo metricbeat setup -e -E output.logstash.enabled=false -E output.elasticsearch.hosts=['localhost:9200'] -E setup.kibana.host=localhost:5601`
and
`# metricbeat setup -e`
- if I monitor multiple servers, how does it work ? Should you create multiple indexes ?

Only just started experimenting with `metricbeat` so in no way an expert 🙂

Starting `metricbeat` without any arguments means it uses _defaults_ for Kibana host and output (which I think is Elasticsearch). The assumption is that both Kibana and Elasticsearch is on the same host (localhost) and are listening on their default ports.

When you monitor several machines with `metricbeat` you are probably sending the metrics to a central Elastic Stack setup. This means you have to change _localhost_ in the `metricbeat` config to wherever Kibana and Elasticsearch is.

You should be able to use a shared index for all `metricbeat` metrics. Usually you would have a rotating daily index. This is the default and `metricbeat`will do that by default if it connects directly to Elasticsearch. If you go through Logstash, you might have to configure it separately.
Hope that helps.

Thanks for these informations. I did not manage to monitor other servers. I opened 2 new questions :
