Hi Team, Memory usage increased to more than 90 while running Elastic search service on window machine. I am using elastic version 7.0.1 / my system RAM is 4gb. Can you please help me how to handle / what configuration need to use in elastic search config file. In the task-bar java JVM taking so much memory usage. Also try to set these setting in jvm.option config fileç ## You should always set the min and max JVM heap ## size to the same value. For example, to set ## the heap to 4 GB, set: ## -Xms2g -Xmx2g ---

Please format your code, logs or configuration files using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable. Or use markdown style like: ```` ``` CODE ``` ```` This is the icon to use if you are not using markdown format: ![image](https://us1.discourse-cdn.com/elastic/original/3X/7/e/7e6e239431ec2d71cbf1beef741f2e93e7cc762c.jpg) There's a live preview panel for exactly this reasons.

Hi David, Sorry for the wrong format. I am facing network issue, So I coudn't connect with the elasticsearch server right now. Once it get start working I will share all the details. Meanwhile can you share some general config setting which we need to take care for elastic search config to improve performance. ---

Hi @dadoonet, I have just uninstall & then re-install the elastic-search version 7.0.1 in my window machine. When I run this service. In the task bar the physical memory reserved by the Java(TM) Platform SE binary version (jre-8u201) is 93 %. File-beat service has been stop at this moment. I am not using any custom index to verify this issue. How can I control this ? I appreciate your help. Result of GET \_cat/health?v: ``` epoch timestamp cluster status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent 1558352777 11:46:17 elasticsearch green 1 1 2 2 0 0 0 0 - 100.0% ``` GET /\_cat/indices?v: ``` health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open .kibana_task_manager Ld6OEiyxTmqlqlyAUKPCkA 1 0 2 4 45kb 45kb green open .kibana_1 AALbkTVAQLa7XIAI87b5Yg 1 0 3 0 13.9kb 13.9kb ``` Output of GET /\_cat/shards?v: ``` index shard prirep state docs store ip node .kibana_1 0 p STARTED 3 14.2kb 127.0.0.1 DEV-APP .kibana_task_manager 0 p STARTED 2 45.6kb 127.0.0.1 DEV-APP ``` Let me know if you require more information. ---

> [@Sharma3007](#): > > When I run this service. In the task bar the physical memory reserved by the Java(TM) Platform SE binary version (jre-8u201) is 93 %. Can you share how much memory the jvm is using.? Also, I'd recommend using a more recent JVM. I believe that Elasticsearch now ships a default one with the distribution so I'd use that one instead. ---

JVM using 60% memory. So Ideally which version we need to use for 7.0.1 version? ---

Thanks for the support . Give me a half an hour. I am traveling to home now. The memory using by JVM is arround 2gb aprox. ---

That sounds correct as you set `2gb` in the configuration file. What is the problem then? ---

So you asked to use 2gb. It is using 2gb. What's wrong? ---

Its taking little bit more than 2gb. if I am not wrong. Issue is that While running elastic search it is consuming 97 % memory. Ok, Got it, If I stop running ELK the system taking 48 %. So If i use 1gb, Can we control this about to 70-80%? ---

> [@Sharma3007](#): > > Issue is that While running Elasticsearch it is consuming 97 % memory. That's inexact. It's not elasticsearch which is consuming 97% of the memory but Elasticsearch + all the other processes which are running on your machine. Proof is: > [@Sharma3007](#): > > Ok, Got it, If I stop running ELK the system taking 48 %. Yeah. You have yet half of the memory resources of your machine used by windows and other programs. My guess is that is not a production machine, right? > So If i use 1gb, Can we control this about to 70-80%? If you use 1gb, then elasticsearch will use 1gb. If other processes uses 3gb, then you will use 100% of the RAM. ---

Yes , its not a production env. If I use 1gb then cpu usage increase. I think 2gb is correct. What else we need to set in elastic search. ---

So if it's a dev environment, why do you care so much? Anyway it's always better (and a best practice) to isolate elasticsearch from any other process. Ie, only elasticsearch should be running on your machine. If you have only 1gb, then you should have a few number of indices / shards and not a big volume of data. ---

Thanks for your Support David, Actually I am new in ELK and its my responsibility to implement centralized logging in our application. so its a good practice to know about elastic search pros & cons before we move to the production env. Before we move on production We want to check all the area or gap. ---

That's a good idea to check that indeed. That looks a bad idea to draw conclusions on a system which is not the target though. To start quick and easy you can also think of using our [cloud.elastic.co](http://cloud.elastic.co) service. ---
