Smith Cruise updated SPARK-31987:
---------------------------------
    Description: 
I know in Spark 3.0, it supports Prometheus Sink. But I don't know where to get 
metrics about executors. I want to fetch realtime executor's 
*_filesystem.hdfs.read_bytes,_* etc.

 

I have tried several paths, but it doesn't work. Could you please tell me the 
Prometheus metrics path about all executors?
