@Matt Thanks for reply. My point behind "Nifi Slow Response" is UI gives slow response in some conditions i.e. 1. When I open configuration model window of any processor. 2. When I click on apply button after configuration. 3. When I am going to open controller services to configure one of my controller. 4. When I reload my Nifi instance. In all the above cases sometimes it works fine and respond me in a second or two but sometime it take 20 sec to 1 min or more then 1 minute. Now I want to know that I have enough memory still I am facing this type of response. And I use my NIFI with KYLO so I wont able to disable my processor, Is there any other way to solve this problem? Max Timer Driven Thread Count is set to 20 Max Cron Driven Thread Count is set to 50. Thanks in advance ... View more

Thanks Shu for quick response. According to you, I can disable all invalid processor but I won't able to disable all stopped processor as 90% stopped processor in my nifi are useful and I can run it on time to time. And there may be possibilities of increase in no. of processor. When I check memory usage using "system-diagnostics" rest api then it give me below output: {"systemDiagnostics":{"aggregateSnapshot":{"totalNonHeap":"831.29 MB","totalNonHeapBytes":871669760,"usedNonHeap":"796.05 MB","usedNonHeapBytes":834719376,"freeNonHeap":"35.24 MB","freeNonHeapBytes":36950384,"maxNonHeap":"-1 bytes","maxNonHeapBytes":-1,"totalHeap":"19.55 GB","totalHeapBytes":20992491520,"usedHeap":"8.25 GB","usedHeapBytes":8862073056,"freeHeap":"11.3 GB","freeHeapBytes":12130418464,"maxHeap":"19.55 GB","maxHeapBytes":20992491520,"heapUtilization":"42.0%","availableProcessors":8,"processorLoadAverage":10.91,"totalThreads":428,"daemonThreads":201,"uptime":"00:23:16.322","flowFileRepositoryStorageUsage":{"freeSpace":"314.39 GB","totalSpace":"1.43 TB","usedSpace":"1.12 TB","freeSpaceBytes":337573191680,"totalSpaceBytes":1572096000000,"usedSpaceBytes":1234522808320,"utilization":"79.0%"},"contentRepositoryStorageUsage":[{"identifier":"default","freeSpace":"314.39 GB","totalSpace":"1.43 TB","usedSpace":"1.12 TB","freeSpaceBytes":337573191680,"totalSpaceBytes":1572096000000,"usedSpaceBytes":1234522808320,"utilization":"79.0%"}],"provenanceRepositoryStorageUsage":[{"identifier":"default","freeSpace":"314.39 GB","totalSpace":"1.43 TB","usedSpace":"1.12 TB","freeSpaceBytes":337573191680,"totalSpaceBytes":1572096000000,"usedSpaceBytes":1234522808320,"utilization":"79.0%"}],"garbageCollection":[{"name":"G1 Young Generation","collectionCount":1471,"collectionTime":"00:05:30.811","collectionMillis":330811},{"name":"G1 Old Generation","collectionCount":0,"collectionTime":"00:00:00.000","collectionMillis":0}],"statsLastRefreshed":"20:06:22 IST","versionInfo":{"niFiVersion":"1.4.0","javaVendor":"Oracle Corporation","javaVersion":"1.8.0_77","osName":"Linux","osVersion":"3.10.0-514.el7.x86_64","osArchitecture":"amd64","buildTag":"nifi-1.4.0-RC2","buildTimestamp":"12/04/2017 19:55:41 IST"}}}} As you can notice that, I have provided max 20GB memory. So, I think this is enough memory to run nifi smoothly with 15k+ no. of processor. As there is no limit of no. of processor dragged on canvas then what can I don to run nifi smoothly with 15k+ or 20k+ processors. Please let me know as soon as possible. Thanks in advance. ...

Hello, Thanks for replying soon, It works fine. But I am getting one more problem with input port and remote process group. I have GetFile processor & RemoteProcessGroup inside Group1 & when I am going to connect both using input ports then I am getting drop down of all inpurt ports which are pl aced in root canvas. But I want to connect with "Group1_Port1" input port that are also placed inside my "Group1" process group. But I am not getting this input port in drop down when I connect GetFile processor with remote process group. Is there any way to connect GetFile processor with RemoteProcessGroup with port that are placed inside Group1 not on root canvas. I have also captured screen shot of my flows, Please check & reply as soon as possible. Thank ... View more
