You sometimes see this if you have threads running for a while (e.g. long running processes like TailFile, or Listening processes). If you increase the number of concurrent tasks, you will also see this go up.</P> Wed, 24 Aug 2016 15:14:31 GMT sball 2016-08-24T15:14:31Z https://community.cloudera.com/t5/Support-Questions/What-s-the-meaning-of-the-number-label-on-NiFi-processor/m-p/117725#M80508 <P>Hi,</P><P>Maybe this is a newbie question, but what's the meaning for the number that appears on the upper-right corner of the processor in this creenshoot ?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="6916-screen-shot-2016-08-24-at-95639-am.png" style="width: 415px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/22997iE1FBFBB9A7235355/image-size/medium?v=v2&amp;px=400" role="button" title="6916-screen-shot-2016-08-24-at-95639-am.png" alt="6916-screen-shot-2016-08-24-at-95639-am.png" /></span></P><P>Thanks</P> Mon, 19 Aug 2019 10:47:51 GMT https://community.cloudera.com/t5/Support-Questions/What-s-the-meaning-of-the-number-label-on-NiFi-processor/m-p/117725#M80508 tim_david1954 2019-08-19T10:47:51Z https://community.cloudera.com/t5/Support-Questions/What-s-the-meaning-of-the-number-label-on-NiFi-processor/m-p/117726#M80509 <P>That is the number of threads currently running in the processor.

The number in the upper right corner may not represent a still running thread. In your screenshot above, the TailFile processor shows as having recorded the completion of 473,336 Tasks (Each task using a thread to complete) and a total cumulative thread time of only 2 min, 52 seconds and 334 milliseconds over the past 5 minutes.</P><P>Long running threads will show much different stats in the Tasks/Time field.</P> Wed, 24 Aug 2016 19:53:10 GMT https://community.cloudera.com/t5/Support-Questions/What-s-the-meaning-of-the-number-label-on-NiFi-processor/m-p/117727#M80510 MattWho 2016-08-24T19:53:10Z https://community.cloudera.com/t5/Support-Questions/What-s-the-meaning-of-the-number-label-on-NiFi-processor/m-p/117728#M80511 <P>What is a task in this context ? reading a line ?</P> Sat, 10 Sep 2016 23:51:45 GMT https://community.cloudera.com/t5/Support-Questions/What-s-the-meaning-of-the-number-label-on-NiFi-processor/m-p/117728#M80511 tim_david1954 2016-09-10T23:51:45Z
