Setting the Black List Properties

In some rare cases, the VMware Performance Agent can encounter ESX® hosts and virtual machines for which it cannot collect data. To prevent these problems, the VMware Performance Agent detects these entities, excludes them from data collection, and adds them to the agent black list.
Any metrics associated with these objects are not included in roll up performance metrics. When an entity is added to the agent black list, an agent message and alarm are generated makes you aware of the problem so that you can investigate it further in the monitored VMware® environment. When the issue with the entity is resolved, it can be removed from the agent black list. The next available performance collection includes this entity in the data collection request.
Each ESX host or virtual machine entry in the user black list should include the Managed Object Reference (MOR) value. The MOR value is assigned to monitored objects in the monitored VMware environment and is collected by Foglight for VMware. This value is stored in the Managed Object Reference property of ESX host and virtual machine objects. You can use the Data Browser to find out the MOR values for those ESX hosts or virtual machines that you want to exclude from data collection.

Collector Name: The name of the collector. A collector is a component that captures specific type of metrics. Existing collectors are: Relationship And Hierarchy Data, Inventory Entity Properties, Performance Metrics, and Events Collection.
Default Collection Interval: Contains the length of the default collection interval. The default collection intervals for the existing collectors are:
Time Unit: Contains the time unit for measuring the default collection interval: milliseconds, seconds, minutes, hours, or days.
Fast-Mode Collection Interval: Contains the length of the collection interval when the agent is running in fast mode.
Fast-Mode Time Unit: Contains the length of the collection interval when the agent is running in fast mode.
Fast-Mode Max Count: Contains the maximum count of entries when the agent is running in fast mode.
