A tool for visually re-organizing process groups on a running Apache Nifi cluster. This tool uses the Nifi REST API to fetch the list of components in the process group, builds an in-memory graph of the components and invokes the Graphviz library to determine new positions for the components to re-organize them in a visually pleasing manner, and then updates components' positions using the Nifi API.

This project was developed using:

• Python 2.7.15
• The following Python libraries:
  • pygraphviz 1.5
  • nipyapi 0.11.0

Simply provide the script with the URL of the Nifi API on the Nifi instance, and the process group ID that you would like to organize, e.g.:

python organize-nifi.py localhost:9999/nifi-api c93b2b2f-ddce-41b9-bc0a-f6e633db86dc
