@adhishankarit There is nothing you can pull form the NiFi Rest-API that is going to tell you about successful outcomes form processor execution on a FlowFile. Depending on data volumes, this also sounds like a resource expensive endeavor. That being said, NiFi does have a Site-To-SIte (S2S) Bulletin reporting task. When a processor throws an error it will produce a bulletin and this reporting task can capture those bulletins and send them via NiFi's S2S protocol to another NiFi instance directly into a dataflow were you can handle via dataflow design however you like. Only way you can get INFO level logs in to bulletins is by setting the bulletin level to INFO on all you processors. This only works if you have also configured your NiFI logback.xml so that all NiFi components log at the INFO level as well. Downsides to this: 1. Every processor would display the red bulletin square in upper right corner of processor, This makes using this to find components that are having issues difficult 2. This results in a lot of INFO level logging to the nifi-app.log. You mention edge nodes. You could setup a tailFile processor that tails the nifi-app.log and then send via a dataflow that log data via FlowFiles to some monitor NiFi cluster where another dataflows parses those records via a partitionRecord processor by log_level and then routes based on that log_level for additional handling/notification processing. Downside here: 1. Since you what to track success, you still need INFO level logging enabled for all components. This means even this log collection flow is producing log output. So large logs and logs being written to even when actual data being processed in other flows is not happening. NiFi does have a master bulletin board which you could hit via the rest-api, but this does not get you past the massive logging you may be producing to monitor success. https://nifi.apache.org/docs/nifi-docs/rest-api/index.html Hope this gives you some ideas, Matt
