The Metrics service provides operation to list metrics. A metric is a fundamental concept. It means a measurable aspect or property. For instance, temperature, count, velocity, data size, bandwidth. Warning: This service is available as Technology Preview. These are early access APIs provided to test, automate and provide feedback on the feature. Since this can change based on feedback, VMware does not guarantee backwards compatibility and recommends against using them in production environments. Some Technology Preview APIs might only be applicable to specific environments.
