Understanding Nifi Processors fields

elloyd — Sun, 18 Aug 2019 04:11:49 GMT

I know this may seem like a newbie question but I would like some understanding exactly of the fields on the Nifi processors.

The reason I want to know is because often times I have a large number sitting in the OUT field and I suspect that means its queued but then what is the purpose of the queue in the transfer between the processors if that is the case? Often times my data will stop being produced and I will have to refresh refresh refresh waiting for the OUT fields and queues to finally "unclog"

The "Out" number is the (5 minute rolling window) amount of data (count of flow files / size of flow files) that the processor has transferred (not that is queued). Check the Anatomy of a Processor section of the NiFi User's Guide, it has explanations of the statistics and other indicators on a processor.

That Matt. Im having a data loss issue I cannot figure out and this clarified that thinking they weren't in the "queue of the processor" isn't the culprit...
