Property Value

The default value of this property is False.

When this property is false (which is usually the default), the producer will publish all metric data changes collected since last time the data was published. Consequently, there can be multiple entries for the same metric in the payload. Note that when the normal polling mechanism is used without further customization, metric data is only updated at most once during the poll, and therefore even with this setting, each metric appears no more than once in the generated payload.

When this property is true, the producer will only publish the last data known for each metric. Any previous changes made since the last publish are ignored.

If your code calls the PublishDataPayload method, and this property is true, the payload will be sent only with the last data for each metric. If this property is false, it will be sent "as is" (if there are multiple changes for the same metric, they will be all included in the payload).

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
