I have 2 questions :

I have installed ELK on a different machine and am able to reach kibana but not elasticsearch. When I ping I see http://:9200/ "mmm...can’t reach this page" as if the address is incorrect.

When logstash started I see its started with `/bin/java -Xms1g -Xmx1g` where can I change those params ?

Kindly suggest.

Did you config a valid network IP in elasticsearch.yml ?

If you access _ **"http://\<your\_external\_server\_ip\>:9200"** _ in the browser gives some error ?

You can change the jvm size on **_jvm.options_** file in the elasticsearch configuration directory.
