-----------------------------------
Summary: Storm metrics feature improvement: support per-worker
level metrics aggregation
Key: STORM-2006
URL: https://issues.apache.org/jira/browse/STORM-2006
Project: Apache Storm
Issue Type: Improvement
Components: storm-core
Affects Versions: 1.1.0
Reporter: Jungtaek Lim
Assignee: Jungtaek Lim
Storm provides per-task level metrics which could be huge when topology has a
number of tasks.
Task level metric is useful for determining load balance between tasks, but it
doesn't need to be time-series fashion.
Before introducing topology level component like TopologyMaster for JStorm, we
can utilize SystemBolt to aggregate task level metrics to per-worker level
metrics.
We should provide options and this feature should be turned off by default to
keep backward compatibility.
