Recommendations are a list of recommended steps to be taken to resolve a problem or alert. The Actions capability within vRealize Operations allows the vSphere administrator to act on the Recommendation. For example, for the Recommendation Add CPU Capacity to a Virtual Machine, an Action that carries out this Recommendation is associated with it.
Out-of-the-box actions are carried out using the vCenter Python Actions Adapter. This runs Python scripts against your vCenter(s) to carry out the tasks defined by the Actions.
