Hi! We have a stand alone  nifi server v1.15.3 deployed to Windows server 2019 data center edition. It runs on java 1.8.0_33. We recently noticed that the nifi service does not seem to pick up the log rotation and retention settings in C:\nifi-1.15.3\conf\logback.xml. We have received some help under https://community.cloudera.com/t5/Community-Articles/Understanding-how-the-logback-xml-configuration-in-NiFi/tac-p/361419#M6616 and tested the configuration that master guru tested under nifi 1.19.1; unfortunately, the log rotation did not happen. Here is the logback.xml I am using: <?xml version="1.0" encoding="UTF-8"?> <!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.
