how to change the in,out,read/write time in Apache NIFI?

Hello,

My NIFI flow is successfully run

After that I have seen that the In,Read/Write,Out in processor view

But after 5 min the all information is flush from processor view

I check the processor code, there is no code for flush information after 5 min

that is happen in every processor

I have to change that time, how can I do that

@Mitthu Wagh the 5-minute window is not currently configurable. However, NiFi does take a snapshot of these values (and several others) every 1 minute (by default) and when you right-click on a Processor, you can go to Status History. This will graph that value over time. By default it will grab those 5-minute statistics every minute for 24 hours. This can be changed by updating the "nifi.components.status.repository.buffer.size" and "nifi.components.status.snapshot.frequency" properties in nifi.properties. You could also get these values via a Reporting Task if you wanted to push them somewhere else such as Grafana for longer-term storage.

@Mitthu Wagh

There is no way to change the 5 minute running average on the processors.

What are you looking for?

You can still see the stats from the processor by hovering the cursor over the processor and right=click, then a menu pops up and you can see the Status History of the processor:

A new window opens with a choice of stats to view
