Lehel Boér commented on NIFI-9183:
----------------------------------

[~exceptionfactory] Thank you for your ideas! This feature is similar to 
diagnostics, which is also included in nifi.sh. I followed the pattern and 
added a new command to it. What benefits can we gain by wrapping it in another 
bash script? Regarding user experience it is easier to remember few scripts, I 
believe we should keep the number of them to a minimum. For the time being, a 
coarse granularity interval is sufficient.

> The status history can only be accessed via the nifi-api REST endpoint. Given 
> that these API calls are replicated across cluster nodes, we should add a 
> command-line option to save the status history of only one node.
