 A single diagnostic setting can define no more than one of each of the destinations. If you want to send data to more than one of a particular destination type (for example, two different Log Analytics workspaces), then create multiple settings. Each resource can have up to 5 diagnostic settings.

 > Sending multi-dimensional metrics via diagnostic settings is not currently supported. Metrics with dimensions are exported as flattened single dimensional metrics, aggregated across dimension values. *For example*: The 'IOReadBytes' metric on an Blockchain can be explored and charted on a per node level. However, when exported via diagnostic settings, the metric exported represents as all read bytes for all nodes.
