Hi again, This is a bit more complex because I see some metrics change every time Prometheus is scraping (15 sec.) The following metrics is updated frequently: nifi_size_content_queued_total nifi_amount_items_queued nifi_amount_items_output nifi_amount_bytes_received
But if the rate of flowfiles is very low (1 every 5-10 minutes) nifi_size_content_input_total is showing the same value for 5 minutes. The value change then new files arrived to the process (about every 1 minutes) but the values looks like it comes from the 5 minutes stat. Not like the metrics above. kind regards Jens M.
