Hi Bobby, I am using Storm 1.1.0. Oh, I forgot. F.Y.I, before I turn on the feature, the section is displayed. However, according to kishorvpatil's comment(https://issues.apache.org/jira/browse/STORM-1157?jql=text%20~%20%22Worker%20profiling%22) , it shouldn't. Is this a problem? In addition, in the first place, I forgot to sync storm.yaml to all worker nodes. After sync, the Storm cluster can be started but topologies can not run. So I checked logs and found there were a lot of errors about Netty. Connection is refused to some workers. And some of my workers have OpenJDK installed. I do not know whether there is causal link here. If I want to use a different profiler, how to set worker.profiler.command? Set to path relative to $JAVA_HOME/bin? And worker.profiler.childopts?

That should be enough. There might be a bug in the ui code though. What version of storm are you using? Also did you select any workers to profile? - Bobby On Tuesday, August 8, 2017, 8:53:10 PM CDT, ? ?? <wangchunc...@outlook.com> wrote: Hi, I want to enable Storm's worker profiling feature, but failed. The action buttons in Profiling and Debugging section are disabled. Below is the related configuration. If my configuration is wrong, would somebody tell me how to do this?
