Ideally, {es} should run alone on a server and use all of the resources available to it. In order to do so, you need to configure your operating system to allow the user running {es} to access more resources than allowed by default.
The following settings must be considered before going to production:
By default, {es} assumes that you are working in development mode. If any of the above settings are not configured correctly, a warning will be written to the log file, but you will be able to start and run your {es} node.
As soon as you configure a network setting like network.host, {es}
assumes that you are moving to production and will upgrade the above warnings
to exceptions. These exceptions will prevent your {es} node from
starting. This is an important safety measure to ensure that you will not
lose data because of a malconfigured server.
