@rahul_ars  You can use the "UpdateCounter" [1] processor to create counters and update the count on them (up and down).  The "Counter Name" property accepts NiFi EL, so you can use attribute son FlowFiles to dynamically update a counter uniquely by FlowFile traversing same dataflow path.  This will allow you to consolidate within your dataflow(s) to reduce the number of processors needed.  Fewer processors can lead to better performance through reduced resource utilization. The "Counters" UI is found under the NiFi Global menu in the upper right corner of the NiFi UI.
