UPDATE (10/2/2021) Sumo Logic is now beta testing ARM64 support via a new collector based on Open Telemetry. You can find more information about this at https://help.sumologic.com/Beta/Sumo_Logic_Distribution_for_OpenTelemetry and the instructions to set it up at https://github.com/SumoLogic/sumologic-otel-collector/blob/main/docs/README.md.
Please contact support if you wish to be added to the Beta program for Open Telemetry.
The Sumo Logic collector installer doesn't support ARM(32/64) based architecture.
This is because Sumo Logic does not provide the Collector Source code as open-source and we do not have plans to supply a Collector specifically built, tested, and supported under the ARM architecture.
