-----------------------------------------
Summary: CPU/Memory/Network metrics collection
Key: STORM-899
URL: https://issues.apache.org/jira/browse/STORM-899
Project: Apache Storm
Issue Type: New Feature
Reporter: Robert Joseph Evans
There are many use cases where it would be great to know how much
memory/cpu/network a particular bolt/spout is using, and how much of that
network is being used to send data to specific bolt instances downstream.
This can be used to improve the scheduling of a topology, and also to provide
automatic elasticity to a topology.
Collecting these metrics is not too difficult, but being able to get them on a
per bolt.spout basis is difficult. Perhaps STORM-891 will make it simple for
us to support this.
These metrics should flow back to nimbus.
