How can I find out size of a current queue in NiFi if I can't access UI ?

Explorer

Hello!

 

So I can't access NiFi UI because the server if probably down exactly because of amount of files that have been stuck at queue. So the question is how can I find out the size of the queue for the moment using may be logs or maybe there are some other ways to do so?

 

Thank you beforehand!

Details you can only get through UI or API , considering web endpoint is reachable, Seems in this case NiFi service is up but UI is not available or NiFi service is completely down , can be confirm by checking its process status. So you need find way to bring back the NIFI service along with UI in minimalistic load by stopping all flows by setting nifi.flowcontroller.autoResumeState to false and start the service, by doing this nifi will start with all the queued data but it will not do any processing, this can give you the UI but since you have said that are too much data so startup will take time.
