Hi, it works for me, but I am using AEM ... I am not an expert in this area, but looking at the code[1] it seems that it only reads existing data from the repository. But if you use the existing Oak class, you should have that editor already in place so that this data exists...
Maybe Thomas Mueller can help here? [1] https://github.com/apache/jackrabbit-oak/blob/trunk/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/index/counter/jmx/NodeCounter.java Am Mi., 3.
