--------------------------------------
Summary: What does AssignedMemory in Storm UI mean?
Key: STORM-4080
URL: https://issues.apache.org/jira/browse/STORM-4080
Project: Apache Storm
Issue Type: Question
Components: storm-ui
Reporter: Anand Hariharan
Attachments: Screenshot 2024-09-08 at 12.48.03 PM.png
I have a topology running in one machine with 3 worker nodes. In the storm UI,
Worker Summary shows some number in "AssignedMemory" column. What does that
mean? I observed that it has a linear relationship with the no. of executors.
i.e it is always 128 times the no. of executors. What am I missing?
storm.yaml
{code:java}
supervisor.slots.ports:
- 6700
- 6701
- 6702
supervisor.childopts: " -Xms512m -Xmx1024m -ea"
worker.childopts: " -Xms1024m -Xmx2048m -Xlog:gc:artifacts/gc.log -ea" {code}
Attached screenshot for reference.
PS: I understand that running one topology in more than one worker in one
machine doesn't make any difference. I am just experimenting.
