+### Processor Metric Response Nodes
+
+Each processor can have its own metrics. These metric nodes can be configured in the minifi.properties by requesting metrics in the \<ProcessorType\>Metric format, for example GetTCPMetrics to request metrics for the GetTCP processors. Besides configuring processor metrics directly, they can also be configured using regular expressions with the `processorMetrics/` prefix. For example `processorMetrics/Get.*Metrics` will match all processor metrics that start with Get.
