The System Insight forwarding agent allows you to stream metrics samples from a workflow to the System Insight service. This enables you to send any data that you are processing in a workflow as metrics.
System Insight is not built to store every single UDR processed by. It provides aggregate or sampled metrics, not exact values.
Note!
The greater amount of metrics samples from a workflow to the System Insight service, the more likely it is that performance of the workflow is affected.
