Unable to install Logstash because it can not find JAVA\_HOME I did not install JAVA because it is included in ELK. Elasticsearch, Kibana and Logstash are on the same server. Elacticsearh and Kibana works. But how to configure the installation of Logstash ? I am on Ubuntu 18.04 ``` ubuntu@monitoring-example-com:~$ sudo apt install logstash Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: logstash 0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded. Need to get 173 MB of archives. After this operation, 299 MB of additional disk space will be used.

I did not understand your answer. According to the documentation, JAVA is included in ELK and there is no need to install it [https://www.elastic.co/guide/en/elasticsearch/reference/current/setup.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup.html) ---

That's for Elasticsearch, not for Logstash. So you either need to tell Logstash to use the bundled one in Elasticsearch - which I am not sure if we support - or install your own. ---
