             Summary: Zero Values for Assigned Mem (MB) in Topology Summary and 
Used Mem (MB) in Supervisor Summary
                 Key: STORM-3768
                 URL: https://issues.apache.org/jira/browse/STORM-3768
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-ui
    Affects Versions: 2.3.0
         Environment: Linux storm 4.9.0-15-amd64 #1 SMP Debian 4.9.258-1 
(2021-03-08) x86_64
OpenJDK 64-Bit Server VM (build 13.0.2+8, mixed mode, sharing)
Python 2.7.13 / Python3 3.5.3
            Reporter: Jonas Krauß

We have recently built storm 2.3.0-SNAPSHOT from git with commit hash 
4a1eea700766da2f175ac7eaba6064f0d7f0ff03 because we needed the bugfix in 
STORM-3652.

It seems in this built information about the sum of the used memory is lost (it 
was working before in 2.2.0, release version). Individual topologies/components 
still get their memory assignment displayed, but the total is missing. This 
affects the root view (*index.html*) of the UI, where information is missing in 
the *supervisor section* (displayed value for used mem is zero), as well as the 
topology view (*topology.html*, displayed value for assigned mem in *topology 
summary* is zero).
