I have a 3 node ELK Cluster - with two logstash and 1 kibana server . When i start my Elk cluster it is giving an error in two nodes and fails. it is all realted to Jvm memory error. I have attached the error screenshot. can you please let me know how to increase the jvm memory. i have added a jvm.option file , but it is not reading the xms-12g and xmx 12g at all when the cluster starts up. not sure where am i going wrong ---

In this screenshot it shows the node has only 1gb.. while i have allocated xms -12g and xmx- 12g in the jvm.options file . not sure why elk is taking the jvm has 1g. while the node server has 32gb available ---

Where you have put settings? config\jvm.options or config\jvm.options.d\jvm.options ? Must be in: `config\jvm.options.d\jvm.options` ---

Hi Rios, Yes I have put the settings in the jvm.options,.d/jvm.options file . One quick question - in the jvm.options file - just putting this settings is fine is this correct ![image](https://us1.discourse-cdn.com/elastic/original/3X/0/d/0d6ba905735262a3d8095317a6e5582cec4fd5f5.png) ---

You have a space before `-Xms16g` and `-Xmx16g`, try to remove the space and start again as there should be no space. The space can make the config to not be taken in consideration. ---

Please don't post pictures of text, logs or code. They are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them 🙂 ---
