Hey Phil, There are two properties that control this:
nifi.components.status.repository.buffer.size=1440 nifi.components.status.snapshot.frequency=1 min The snapshot.frequency tells NiFi how often to take a 'snapshot' of the stats on your canvas and add to the 'Status History'. The buffer.size says how many of these to hold in memory. So the default is to take a snapshot every minute and keep 1,440 minutes' worth (which is 24 hours). If you want to expand this to a week, you can do so by making the buffer size larger or by making the snapshot frequency less often. Keep in mind, though, that there are a lot of stats being collected so if you have a lot of processors, the amount of heap/memory that gets used up can grow pretty quickly. I'd recommend changing the snapshot frequency to "5 mins" and the buffer size to 2016 to make 7 days' worth of stats. You'll also want to keep in mind that these stats are all stored in memory so if you restart NiFi, you will lose the stats that you've gathered. Of note, I am currently working on NIFI-5466 [1], which should significantly reduce the amount of memory needed to store the stats, especially for processors that are stopped. Hope this helps!

We are interested in seeing things that happen over the course of a week or so Thanks, Phil
