### On-board Diagnostics
On-board diagnostics help ensure that the underlying infrastructure that runs MinIO is configured correctly, and is functioning properly. This test is one-shot long running one, that is recommended to be run as soon as the cluster is first provisioned, and each time a failure scenrio is encountered. Note that the test incurs majority of the available resources on the system. Care must be taken when using this to debug failure scenario, so as to prevent larger outages. OBD tests can be triggered using [`mc admin obd`](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md#command-obd---display-minio-server-obd) command.
