*******************************************************************************
Platform test configuration file reference for Cluster Validation Suite (CVS)
*******************************************************************************

Run host check scripts to validate host-side configurations, such as model load balancing enablement, PCIe checks, kernel version, and ROCm version.

The following sample shows the ``host_config.json`` structure. Replace the values with your cluster's actual versions before running:

See :doc:`/how-to/test-suites/burn-in-diag/platform` for more information on running these tests.

Parameters
==========

The following parameters are available in the platform configuration file. Set each to the expected value for your cluster — the test compares the actual system state against these values.
