Which method allows for checking the health of a Nutanix cluster?

The method that allows for checking the health of a Nutanix cluster is the NCC tool. The NCC, or Nutanix Cluster Check, is a built-in tool specifically designed to assess the health and performance of a Nutanix cluster. It provides comprehensive diagnostics by running a series of tests that evaluate various aspects of the cluster's configuration, performance, and overall health.

NCC is particularly important because it helps administrators quickly identify issues such as misconfigurations, performance bottlenecks, and potential failures. The ability to run these diagnostic checks periodically or on demand supports proactive cluster management and maintenance.

While log analysis and API calls can provide valuable information about cluster activities and configurations, they do not inherently offer the systematic health checks that NCC delivers. Maintenance reports can provide insights into the overall operational status and planned updates but are not an active method for checking cluster health as NCC is. Therefore, utilizing NCC is the best practice for ensuring that a Nutanix cluster remains healthy and operates at optimal performance levels.
