The core Gravwell components require a 64-bit CPU and 64-bit Operating System. Ingesters can run on most popular Operating Systems and Architectures.
The core components (indexer, webserver, searchagent) require a 64bit Linux host with a kernel version 3.2 or better. An experimental ARM64 distribution for the core components is available upon request.
The core set of ingesters are open source and support a wide array of architectures and Operating Systems. However, only AMD64 is officially supported and distributed. Visit our ingester github page for build instructions. For a full list of supported architectures and minimum system requirements see https://github.com/golang/go/wiki/MinimumRequirements.
