Shyam Rajendran commented on STORM-899: --------------------------------------- STORM-919 is being worked on as a related JIRA > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
