Monitoring Nifi Throughput apart from UI any logs or best practices?

[#1]

Is there any way to monitor the throughput of Nifi i.e. how many messages it has processed in a second? Apart from Nifi UI and Ambari is there a way to monitor the throughput for Nifi please like logs as i cant find any detials regarding throughput in nifi logs or in any of the nifi repositories(content, flowfile,db) as well?

The NiFi UI has a Summary page from the top-right menu, as well as stats on each processor by right-clicking and selecting Status History. Both of those views show things like bytes read/written, flow files in/out, etc.

If you want to track this information somewhere else, you can implement a custom ReportingTask to send this information somewhere. This is how Ambari is able to display the stats/graphs, there is an AmbariReportingTask:
