Process –

Root Cause

The memory does not meet the installation requirements of the agent. You need to have more than 500MB of available memory to install it.

Solution

  1. Adding more memory to the server may affect its usage. It is recommended to backup the server before performing any operations and to do so at a convenient time for the business.
  2. Release idle memory on the server by executing "echo 3 > /proc/sys/vm/drop_caches". It is recommended to perform this operation when the business is idle.

Suggestions and Summary

The server on which the ES agent is installed should have at least 500M of remaining memory.
