Hi @Abdelkrim Hadjidj These links were very informative. After reading these and doing some testing I think I have found what I need but it is not available in the version that I have. The option I am looking for is totalSizeCap. If I am reading the notes correctly is available in logback 1.1.8, and I am running Nifi 1.1.1 witch uses logback 1.1.3. Would you happen to know what version of logback is used by the newest version of Nifi? ... View more

This past weekend I had an issue and my nifi-app logs filed up my drive. I have address the issue but I am trying to find out how I can configure nifi to rotate the nifi-app files so it dose not file up my disk space again. Thank you ... View more

Matt, Thank you for your reply. It shows me that I still have a lot to learn about Nifi. 1. This explanation helped me. You mention the Cluster UI. Is that different than http://Node1:8181/nifi? I ask because when I have only one node running I only get a screen telling me "An unexpected error has occurred". 2. For my testing I have it set to run every 5 min. I have created a simple flow. Consisting of ExecuteScript->ExecuteStreamCommand->ExecuteScript-> ExecuteScript->InvokeHTTP. I have tried setting just the first one to “Primary node only”, I have also set them all to “Primary node only”. In these two tests after waiting 30 min. and not getting any data, I simply switch them to “All nodes”, and I start to get data within minutes. I think I should first get my cluster set up properly then come back to this issue. As they say baby steps. I see that you are recommending against using the embedded zookeeper. Do you know of a good link explaining where to get the zookeeper and how to configure it with Nifi? Do you need to have one nifi for each zookeeper? Thank you for all your help. Andre ... View more

I am new to Nifi and trying to learn how to use it. I have set up two servers with Nifi and configured them to be a cluster. I am currently having two issues that I think are related. 1 - If I take one server off line I can not access Nifi. 2 - If I set a work process to execute on "Primary node", it dose not run. If I set it to "All nodes" then I get two copes of the work. Any help would be appreciated. I have included what I think is the pertinent data from both servers for /conf/nifi.properties, /conf/zookeep.properties, and /state/zookeeper/myid. Thank you.
