-----------------------------------
Summary: Introduce 'filter' option to MetricsConsumer
Key: STORM-1700
URL: https://issues.apache.org/jira/browse/STORM-1700
Project: Apache Storm
Issue Type: Sub-task
Components: storm-core
Affects Versions: 1.0.0, 2.0.0
Reporter: Jungtaek Lim
Storm provides various metrics by default, and so on some external modules
(storm-kafka).
When we register MetricsConsumer, MetricsConsumer should handle all of metrics.
If MetricsConsumer cannot keep up with these metrics, only way to keep up is
increasing parallelism, which seems limited. Furthermore, some users don't want
to care about some metrics since unintended metrics will fill external storage.
Though MetricsConsumer itself can filter metrics by name, it would be better to
support filter by Storm side. It will reduce the redundant works for Storm
community.
If we provide filter options, it would be great.
