Policies are event triggers that monitor the activity of the system. Policies respond to predefined events issued by changes in the status or performance of certain defined objects.
Policies are a series of rules, gauges, thresholds and event filters that run certain workflows or scripts when specific predefined events occur in Orchestrator or in the technologies that Orchestrator accesses through plug-ins. Orchestrator constantly evaluates the policy rules as long as the policy is running. For instance, you can implement policy gauges and thresholds that monitor the behavior of vCenter Server objects of the VC:HostSystem and VC:VirtualMachine types.
Orchestrator defines the following types of policy:
Master policies. Policy templates are not linked to real objects. They are abstract sets of rules that define the behavior to implement if a certain abstract event occurs. You can see existing policy templates and create templates in the Policy Templates view in the Orchestrator client.
Policies are instances of a template or standalone event triggers that are linked to real objects, and that are triggered by real-life events. You can see existing policies and create policies in the Policies view in the Orchestrator client.
You can organize policy templates into folders, for easier navigation. The maximum number of policies supported by Orchestrator is 50.
