Prerequisites and System Requirements

Before installation, ensure your server or virtual machine supports Advanced Vector Extensions (AVX), which are required for optimal performance of OpenSearch and related components such as MongoDB (used by Graylog).

Run the following command:

lscpu | grep avx

• If no output is returned, your processor does not support AVX. In this case, consider:
  • Migrating to AVX-compatible hardware,
  • Hosting MongoDB on a separate compatible server,
  • Or exploring alternative deployment architectures.

Note: Lack of AVX support will cause MongoDB and Graylog installation failures.
